Setting Up a New Omni DTF Mini
Ease of setup is one of the benefits of the Omni DTF Mini system. In this article we’ll walk step-by-step through the process of getting your equipment positioned, fully assembled, and loaded with film so it’s ready for your training session.
For demonstrations of the steps, see the embedded videos covering the equipment assembly & setup details and use of the Powder Keeper in their respective sections below. Note that there is also a link to our Unboxing the Omni DTF Mini article and video at the bottom of this page.
Preparing the Space
Power requirements
The Omni DTF Mini’s oven must be powered from its own dedicated 20 amp circuit, while the printer’s more modest power requirements allow it to be used on circuits shared with other devices, including the air purifier. All of the equipment should be powered through surge protectors, rather than plugging directly into an outlet. As with any electronic equipment, damage caused by electrical storms or any irregular power problems is not covered by the warranty, since such damage is not due to a defect in parts or workmanship.
Equipment | AC Voltage | Peak Current |
---|---|---|
Omni DTF Mini printer | 110-120 VAC | 2.5A |
Omni DTF Mini oven | 110-120 VAC | 19.5A |
Air purifier | 110-120 VAC | 1.65A |
Space requirements
It’s necessary to be able to move around the printer and oven to ease doing things like loading new rolls of film, circulating the white ink, cleaning the undercarriage, refilling the powder hopper, and removing completed prints.
Assembly & Setup
Demonstration video
Positioning & Leveling the Printer & Oven
When selecting a desk or bench for the printer and oven, keep in mind that the top surface of the oven’s table or bench should be 16″ to 22″ below the top surface of the printer’s table. This provides a sufficient drop to support the film advancing consistently. Greater distances may result in poor transfers and durability issues due the ink drying too much before powder is applied.
The printer’s four feet are mounted onto bolts which can be rotated to lengthen or shorten their length.
These should be adjusted so that the printer is level, while the feet supporting the film roll bracket (also shown below) should be at their minimum length.
While leveling, keep in mind that the printer’s feet should elevate the bottom of the printer at least 1″ above the surface of the table or bench that it rests on.
The oven assembly’s feet also have adjustable length bolts for leveling the equipment.
Removing the Carriage Lock Bracket
The printhead carriage is locked in place to prevent potential damage due to motion during shipment. Be sure to remove the locking bracket prior to connecting to power and turning on the printer.
The bracket attaching the left side of the printhead carriage to the carriage frame is removed by taking out the two screws that hold it in place.
Loading the Film
First, attach the factory-assembled film roll support bracket to the back of the printer. Remove the five Allen head bolts, line up the bracket with the holes those bolts were removed from, then reinstall the bolts to attach the bracket.
Install the left & right chucks onto the rods and mount the film roll’s core onto the chucks with the roll oriented so that the fill feeds from the top of the roll, passes under the tension bar, then feeds into the rear of the printer.
Lift the white-handled lever at the left-rear corner of the printer to raise the printer’s feed rollers, feed the film under the rollers and center it on the platen, then lower the lever to drop the rollers and secure the film in position.
Hold the end of the film while releasing the rollers again with the lever, feed the film straight through the oven, and tape the end of it to the back of the oven until we’re ready to attach it to the takeup roll core.
Attaching the Takeup Roll Assembly
The following parts are used to assemble the DTF Mini’s takeup roll assembly:
- Mounting brackets (2, left & right)
- Round crossbar
- Rectangular crossbar
- Passive chuck (left)
- Motorized chuck (right)
- Empty roll core
- Philips head bolts (8)
Mount the brackets to the sides of the DTF Mini oven, then insert the round & rectangular crossbars into their respective holes in the brackets. (You may need to loosen the preinstalled lock screws above the brackets’ holes if a crossbar can’t fit through easily.)
Temporarily pull the crossbars out of one bracket side and “thread” the chucks onto the round crossbar and mount it onto the rectangular crossbar with the motorized chuck on the right, then plug in the motor’s cable to the lower jack on the side of the oven.
Finally, install the empty roll core onto the chucks, pull the film under the tension bar and core, then pull it taut and square it before taping the end of the film to the core.
Attaching the Fan Assembly
The fan is packaged with its two mounting brackets and attachment hand-screws.
The four black Allen bolts used to attach the brackets to the oven frame are packaged in a separate bag with other misc. hardware.
Attach the two brackets to the oven frame with the four Allen bolts, then attach the fan to the brackets and connect it to the upper jack on the oven as shown.
The Powder Keeper
The Omni DTF Mini is now set up and ready for your training session.

Omni DTF Mini Daily Startup
Follow the steps demonstrated in the below video or described in the following text each time you start up the Omni DTF Mini to ensure that your first print and every print is top-quality.
Video Demonstration
Startup Summary
- Check the level of the waste ink bottle and empty as needed.
- Check the level of the ink bottles and refill as needed.
- Stir the white ink manually, especially at the bottom of the bottle.
- Turn on the printer power
- The printer will stir the white ink for an additional minute.
Note that this automated stirring is in addition to the manual stirring done in the previous step.
- The printer will stir the white ink for an additional minute.
- Rotate the white ink circulation pump control fully clockwise.
- The white ink will circulate for 5-minutes.
- Turn off the white ink circulation switch after it completes its 5-minute cycle.
- The white ink will circulate for 5-minutes.
- Open & reposition the ink clips.
- Run two head cleanings.
- Print and evaluate a nozzle check.
- Run additional head cleanings if needed to acheive a 90% complete or better nozzle check test pattern print.
Daily Startup Illustrated Details
- Check the level of the waste ink bottle and empty as needed.
- Check the level of the ink bottles and refill as needed.
- It’s important keep the ink level between the minimum & maximum levels shown above to maintain good ink flow and avoid the risk of getting air into the ink lines. It’s recommended to also equalize the levels.
- It’s important keep the ink level between the minimum & maximum levels shown above to maintain good ink flow and avoid the risk of getting air into the ink lines. It’s recommended to also equalize the levels.
- Stir the white ink thoroughly, especially at the bottom of the bottle where the automated stirring mechanism cannot reach, using a non-porous and non-metallic spoon or stirring stick. A non-porous plastic spoon, knife, or stirring stick will work fine. Just be sure to remove the stirring tool when finished stirring. Don’t leave it soaking in the ink.
- Turn on the printer’s power.
- The printer will automatically stir the white ink for 1-minute immediately after being turned on.
- Open the printer’s right-side access panel door and rotate the white ink circulation pump control to its fully-clockwise position.
- The white ink will automatically circulate for 5-minutes immediately after the white ink stirring cycle is completed.
- Turn the white ink circulation controller to its full counterclockwise position (OFF) after its 5-minute cycle completes and before proceeding to the next step.
Failure to turn off the circulation before opening the white ink clips can cause waste ink and air to be pulled into the white ink system. If this happens a significant amount of white ink will be wasted to prime the air out of the white ink system.
- Open the ink clips, after turning off the white ink circulation controller.
- Reposition the ink clips after opening them so they will clamp in a different position when closed.
- Roll the ink tube between a thumb and finger to round out the ink tube if it is somewhat collapsed where it had been clipped.
- Run two head cleanings.
- Print a nozzle check from the Omni DTF Mini UI software.
- If each channel of the nozzle check (cyan, magenta, yellow, black, and 4 white boxes) is 90% complete or better, you are ready to turn on the oven and begin producing prints.
- Run additional head cleanings and nozzle check prints if needed to acheive a 90% complete or better nozzle check test pattern print on each color channel.
- If each channel of the nozzle check (cyan, magenta, yellow, black, and 4 white boxes) is 90% complete or better, you are ready to turn on the oven and begin producing prints.

OmniDTF: Hardware Controls Brief
The OmniDTF has a robust set of hardware controls, making it simple and convenient to operate most routine functions directly from the printer itself. Here’s a brief rundown on the position and function of each of these controls.
Printer Controls
Control Pad
This is the set of pressure-sensitive buttons on the front of the printer, to the right of the platen.
Feed Adjustment: Adjust vertical feed between print passes (use only as directed by Omniprint staff.)
Printhead Cleaning: Run a Light printhead cleaning on both printheads.
Nozzle Check: Print a test pattern to confirm that ink flow is optimal and ready to deliver quality prints.
Cancel Print: Stop printing and remove the remaining print job from the printer’s memory.
Pause: Temporarily stop printing. Pushing Pause a second time will prompt you to continue printing.
Margin Reset: Change the right margin from the default of 10mm (use only as directed by Omniprint staff.)
Carriage Left / Carriage Right: Move the printhead carriage to the left or to the right of its current position. Hold the button for continual movement.
Reverse Feed / Forward Feed: Feed film forward (toward the front of the printer) or backward.
Enter: Submit responses to prompts on the display panel or move the printhead carriage to the Home position (above the capping stations) if there is no prompt
Front Panel Switches
There are three switches positioned directly below the Control Pad. Two of these can generally be thought of as set it and forget it, and the third is essentially an emergency kill-switch. Here are the details.
White Ink Circulation: When toggled to the ON (1) position, white ink is circulated for 1-3 minutes.
Vacuum: This rotary switch turns on and adjusts the suction of the platen’s vacuum. We recommend turning it on and adjusting it to its lowest level for optimal film feeding and platen temperature stability.
Emergency: This red “kill” switch immediately shuts off power to the printer’s electronics when depressed. Once depressed this latching switch will remain engaged and prevent the printer from operating until it is rotated clockwise about ¼ of a turn. It will then pop out and normal operation will be restored.
Heater Controller
The Heater Controller is used to adjust and provide status of the OmniDTF printer’s two film heaters. One heater sits behind the platen, to preheat the film as it enters the printer chassis. The second one is under the platen, to keep the film warm as it is being printed on. Heating the film helps the ink set quickly, so the white layer can be applied just seconds after the color layer.
Front Heater & Back Heater: The Front Heater and Back Heater numeric displays report each heater’s current temperature in Celsius. When changing the temperature setting, the displays show the changes being selected.
Power: The Power button turns both heaters ON or OFF, toggling their current status. The heaters automatically turn off when the printer is switched off. If the heaters were on when the printer was switched off then they will automatically turn back on when the printer’s power is turned on.
Select: To change a temperature setting for a heater, that heater must first be selected by pushing the Select button, after which the numeric display of the currently selected heater will flash. The first press of the Select button selects the Front Heater. A second press selects the Back Heater. A third press of the Select button exits the temperature adjustment mode.
Temp: The Temp (+) and Temp (-) buttons are used to raise or lower the temperature setting of the currently selected heater.
Dust-Curing Machine Controls
The Dust-Curing Machine has its own power cord and switch, so is plugged into a separate outlet from the printer. While the two pieces of equipment are powered and controlled independently, they form a single, complementary system.
Most of the controls on the Dust-Curing Machine are found on a single control panel on the right side of the equipment. We’ll detail each of those first and then move on to the exceptions.
Control Panel
Here you’ll find switches for Power, Dusting, Shaking, Curing, and an Emergency off switch. In addition to these switches, there are also granular controls for setting the dusting speed, shaking speed, and curing oven temperature.
Power Switch
The Power switch in the lower-left corner of the Control Panel is the master power for all other switches and functions of the Dust-Curing Machine. When this switch is OFF, all other switches and controls of the Dust-Curing Machine are inoperable because there is no power being supplied to any part of the unit.
Emergency Switch
The round, red Emergency button above the Power switch will immediately shut off power to the Dust-Curing Machine when depressed.
This is a “latching” switch which, once depressed, will prevent the Dust-Curing Machine from operating until the switch is released. If you ever find that the Dust-Curing Machine won’t turn on from it’s power switch, make sure this switch is not depressed.
To release the switch, rotate the handle clockwise for approximately ¼ turn. Once the switch is rotated clockwise, a spring will push it back out and power will then be restored to the Dust-Curing Machine if, or as soon as the Power switch is in the ON position.
Dusting Switch & Speed control
There are two Dusting controls used to add DTF Powder onto the film as it passes through the powder application chamber.
Dusting switch: This switch toggles the power to the rotating Dusting blades in the DTF Powder Feeder to sweep powder into position to cascade onto the film through narrow slits in the bottom of the powder feeder.
Dusting Speed dial: This dial is used to adjust the rotational speed of the DTF Powder Feeder. The further it is turned clockwise the faster the feeder will rotate and sweep DTF Powder into position to be dusted onto the film.
Shaking Switch & Speed control
There are two Shaking controls used to remove excess DTF Powder from the film after it has been applied by the Dusting feature.
Shaking switch: This switch toggles power to the rotating Shaking spindle with short plastic straps that shake the film as they rotate, shaking any excess DTF Powder back onto wet ink or into the Powder Recycle Bin.
Shaking Speed dial: This dial is used to adjust the rotational speed of the Shaking spindle. The further it is turned clockwise the faster the straps will shake the firm to knock excess DTF Powder loose.
Curing Oven Temperature
There are two controls for the Curing Oven. Remember that using a temperature that will effectively cure the ink and melt the DTF Powder is an important part of the DTF production process. We recommend starting with a setting of 120 Celsius and adjusting from there as needed.
Curing switch: The curing switch turns power for the Curing Oven and the Curing Temp Controller ON and OFF.
Curing Temp Controller: The Curing Temp Controller is used to set and monitor the oven temperature, using four buttons and two numeric displays.
When the Curing power is switched on, the upper display shows the current oven temperature, and the lower display shows the temperature setting.
Changing the temp setting
Set button: Push and hold the Set button until the lower numeric display begins to flash.
◄ button: When in the temperature setting mode (having been activated by the Set button), the temperature setting display shows a cursor in the rightmost column of the setting number.
We recommend making temperature adjustment in 5-degree increments, so for most temperature changes you’ll want to adjust from this rightmost position. To change the setting in increments of 10’s, use this button to move the cursor one digit to the left – to the 10’s position.
▼ button: Use this button to reduce the temperature setting at the cursor position.
▲ button: Use this button to increase the temperature setting at the cursor position.
Take-up Roll Motor Switch
This 3-position switch is set to the down position to enable the motor to rotate the take-up roll counter-clockwise (from the perspective of the side of the Dust-Curing Machine controls.) The center position turns the motor off, and the top position is for reverse feeding film backwards, toward the oven and printer.
Transferring a DTF Print
Transferring a finished print to a garment is simple and can be done immediately after DTF printing and curing, or up to a month later. Longer storage times may be possible if carefully stored in an air-tight container and in a climate-controlled environment.
- Prepare your heat press for a DTF image transfer.
Fabric Type | Temp (F) | Pressure | Transfer Press Time | Peel Delay (cold peel film) | Finish Press Time |
---|---|---|---|---|---|
Cotton | 300◦ to 320◦ | 50-70 PSI Stahl’s 5-7 | 20 sec | 60-90 sec | 10-20 sec |
Polyester | 260◦ to 280◦ | 50-70 PSI Stahl’s 5-7 | 20 sec | 60-90 sec | 10-20 sec |
- Cut out the image that you want to transfer to a garment from the film roll or sheet.
- Place the garment to receive the image transfer onto the heat press.
- Place the DTF print on the garment, with the ink & glue side of the film directly against the fabric, positioned exactly where you want it transferred.
- Verify that the collar, shoulders, and any seams are draped off the side of the heat press to ensure proper pressure at the transfer location
- Place a silicone sheet or kraft paper on top of the film.
- Press the transfer onto the fabric using the above table for temperature, pressure, and duration.
- Remove the garment from the heat press, and lay it on a clean, flat, hard surface.
- When using cold peel film, delay this step for a minute or so, until the inked area of the garment has cooled down to room temperature. Carefully peel the film away from the garment at a moderate rate.
- Place the shirt back on the heat press with a sheet of parchment or Kraft Paper or a white silicone sheet between the shirt and the top of the heat press, then perform a final “finish” press for the duration shown above at the same temperature and pressure as the transfer. This further cures the surface of the print and creates a smoother transition between ink & fabric.
The transfer process is now complete!
Print Pro: Setting Up a Print (video)
Print Pro provides a rich set of features to set up a print job using one or more images to automate the creation of “gang run” layouts, making the most efficient use of your film effortless. This article is intended to supplement your Omniprint training as a handy reference to refresh your memory and to use as an annotated checklist of the process steps.
View the below videos or see the following instructions for all the basics of loading & configuring images, then creating and positioning the images onto a Layout.
Loading Images
Loading your images is the first step in creating a print job. You can either use the Print Pro ‘File Browser’ or click on the Print Pro printer icon in the top-left corner of the program’s window and select ‘Open…’ to navigate through the Windows file system and select image files to load.
The latter option is recommended because it lets you make your selection from thumbnails of images, rather than just their filenames.
Whether you’re printing a single design or multiple different images for a print job, you’ll want to load and configure each image individually.
Setting the Image Configuration
As each image is loaded, set the following parameters using the Q Rip tool.
Size the Image
Size the image in the Q Rip window, using the 3rd (bottom) option to rescale the image if needed, ensuring that the width does not exceed 14.25″ for the OmniDTF or 12.5″ for the Omni DTF Mini.
When resizing, be sure the padlock icon option is checked to lock the aspect ratio and prevent distorting the image (see red box in the image).
Position the Image
The default settings of ‘Left’ and ‘Top’ are always used in the Q Rip tool (see green box in the above image.) Changing this setting has no effect on where the image will be positioned on the layout. This is because Print Pro will find the earliest (topmost) point in the layout where each image can fit as they are being added to the print job, maximizing the efficiency of linear film use.
Create a White Underbase Choke
After configuring the image in Q Rip, click on the Image menu tab and then on the White Underbase Choke tool.
Click the ‘OK’ button to accept the default Choke Width value of 2.0.
The image is now configured and ready to be loaded onto a Layout.
If you want to print a Layout with a combination of various images on it, repeat the above steps to open a file, set image parameters, and create a white underbase choke for each image before proceeding.
Creating and Configuring a Layout
Now that any images that we want to print have been loaded and their parameters have been set, we’re ready to create the Layout that the images will be placed onto, using the following steps.
If the Page Layout window isn’t already open, select Open Layout from the Home toolbar
Create a New Layout
Whenever we create a new layout we must also tell the Print Pro software which Environment we want to use for printing the new layout. These Environments are a collection of “presets” that OmniPrint provides to simplify and streamline configuring print jobs.
Click on the Layout menu, then select New, then hover over Omni DTF and select the desired Environment from the list that appears.
The Layout window is then loaded and preconfigured with the parameters of the selected Environment.
Put Opened Image(s) onto the Layout
Images opened and configured using the above steps will appear as thumbnails with their filenames under the Page Layout window’s Opened Image(s) header.
Double-click on any item in the Opened Image(s) list to add it to the Layout.
You can repeat the above step any time to load more images from the Opened Image(s) list onto the layout, or to load more copies of a single image. But there’s a better way to load many copies of an image once it is on the layout.
Duplicating Images on a Layout
Once an image is on the Layout, you can create additional copies of that image on the layout by clicking the Ups option in the toolbar…
…then enter the number of additional copies you want to add to the Layout into the dialog box that pops up and click the green checkmark.
The additional copies of the image will now appear on the Layout.
Note: You can scroll down in the Layout window if you want to confirm the number of copies if they don’t all fit in the window’s view. You can also zoom out and in on the layout by using Ctrl+’-‘ (to zoom out) and Ctrl+’=’ (to zoom in).
That’s how to load images, set their properties, select an Environment for and create a new layout, and place the images onto the layout in Print Pro!
Printing a Layout
To print the Layout, click the Print menu item, then select Print Layout from the toolbar, or just press Ctrl+’p’….
…and make sure your printer is selected in the Print dialog before clicking the ‘OK’ button.
