OmniDTF DirectRIP Environments

Download the file at the bottom of this article (or by clicking here), then use the following process to update the Environments in your installation of DirectRIP for the OmniDTF printer when directed to do so by OmniPrint staff, as needed.

Installing the Environments

The installation process of the Environments is quick and easy.

  1. Download the Environments file to the PC on which you’ve installed DirectRIP.
    1. Extract the OmniDTF.kiee file from the downloaded zip file.
      1. Placing the file on the Windows Desktop is recommended to ease access.
  2. Run DirectRIP.
  3. Navigate in Windows File Explorer to the location in which the OmniDTF.kiee Environments file has been extracted.
  4. Click & drag the Environments file onto the DirectRIP workspace, but not in the Queue Manager subwindow (anywhere within the green box in the below image).

  5. Click the Yes button when prompted with a message of “Already ‘Omni DTF-720×3600’ environment exist.” (The actual environment name will vary.)
  6. When prompted to Select environment settings to use, select ‘Use new environment settings only’ and click OK.
  7. Click OK on the window message of “Media packages imported successfully.”
  8. Exit out of the DirectRIP program, then restart it.

The OmniDTF Environments have now been installed or updated and are now ready for use.

OmniDTF Shutdown Maintenance and Wet Capping

Properly shutting down your OmniDTF printer is very important to ensure that it will be ready to print the next time you start it up. Fortunately, the process is very easy!

Take about 5 minutes to go through these simple steps when you’re finished with your print job.

Curing Oven Shutdown

If you haven’t already done so, start by turning off the Curing Oven’s main power switch. This is a master switch that will cut power to the Duster, Shaker, and Oven — so shutting off any other switches is optional.

Printer Shutdown Maintenance

  1. Press the Printhead Cleaning button on the printer’s control pad to flush any pooled ink out of the capping stations.

  2. Empty the waste ink bottle
  3. Press the Carriage Left button to move the printhead carriage to approximately the center of the printer, easing access to the ink line clips and exposing the wiper blade and capping stations.

  4. Reposition all 8 ink line clips slightly up or down on the ink lines, then clamp them shut.

  5. Use the Carriage Left button to move the printhead carriage to the far left end of its travel, so it is no longer positioned above the heated platen.
  6. Wet an anti-static foam swab or a clean, lint-free cloth with Super Cleaner to thoroughly clean:
    • The full length of the wiper blade
    • The rubber seals surrounding both capping stations

  7. Remove any bits of dried ink on the capping station sponges or seals with tweezers.

Wet Capping the Printhead

  1. Fill both capping stations to the brim with Super Cleaner.

    The wiper blade and capping station seals should now be free of any ink build-up and the capping station sponges completely submerged in Super Cleaner, up to the top of their seals.
  2. Click the WetCap button under the Settings tab in the OmniDTF Windows program.

    This will send the printhead carriage to its docked position and raise the capping station seals to press against the bottom of the printhead plate, bathing it in Super Cleaner within an air-tight seal.

The printer can now be turned off from the power switch on the right side, near the back of the printer.

Power and Ethernet ports

That’s all there is to it.

Congratulations! The printhead maintenance components have now been cleaned and the printhead is wet capped.

OmniDTF Daily Startup

The daily startup routine for the OmniDTF system is very straightforward and can be made even simpler by following a few tips that we’ll include in this brief overview of the process.

Before starting up the printer you’ll want to first run the OmniDTF program on your PC, to establish a connection between the PC and printer when the printer is turned on.

Preliminary Steps

Note that the connection icon in the lower-left corner of the window will flash red until the printer is turned on.

Also, empty the waste ink bottle at the right-rear corner of the printer (left if viewing from the back) if it contains any ink before turning on the printer.

Waste ink bottle

Always check your ink levels before printing and fill the bottles up to the top of the bracket holding the bottles. Be careful not to overfill the bottles because if the ink level reaches the bottle’s fitting where the ink tube enters the bottle as this can cause leakage. Also, check your ink levels throughout the day if you’re doing a lot of printing, and refill as needed.

It’s important to never let the ink level in the bottles get too low, as this can impact ink flow and also risks introducing air into the ink lines.

The final step before turning on the printer is to confirm that the white ink lines are clipped shut. This should definitely be the case since that is an important step of the shutdown procedure, but it’s advisable to double-check now.

Starting up the OmniDTF printer

  1. Turn on the printer using the power switch on the right side, near the back.

    Power and Ethernet ports

  2. Circulate the white ink by turning on the White Ink Circulation switch on the front of the printer if it isn’t already on. It will run for 1-minute when switched on.

  3. Confirm that the rotary Vacuum switch, shown above, is on (not fully counter-clockwise.) It’s recommended to keep this at its minimum strength, which provides plenty of vacuum power to keep the film against the platen without cooling the platen heaters.
The White Ink Circulation and Vacuum switches can be left on at all times so that they automatically engage when the printer is turned on.
  1. Open all eight of the ink clips
  2. Press the Printhead Cleaning button on the printer’s control pad to run a head clean.

  3. Once the control pad display indicates that the head clean is finished, press the Printhead Cleaning button once more to run a second head clean.
  4. Press the Nozzle Check button on the printer’s control pad to print a nozzle check test pattern.

    • If the nozzle check isn’t at least 90% complete on all 8 channels, additional Printhead Cleaning should be done to achieve that standard.
    • Be careful to keep an eye on the fluid level in the waste ink bottle if running multiple head cleans, and be sure to empty it before it gets beyond 2/3 full.
  5. Turn on the curing oven assembly’s main Power switch, along with the Curing switch to begin heating the oven.
  6. Confirm that there is an appropriate amount of powder resting on the film loop and add more as needed.
The previous oven settings will be retained so typically won’t need to be adjusted as part of the daily startup process.

The printer is now ready and you can proceed with production work!

Production Notes

Monitor the status of the following items periodically when printing to ensure trouble-free operation and optimal print quality:

  • Film Alignment: To avoid a possible head strike, ensure that the film running through the printer, across the bridge, and through the oven assembly is now skewed. Pause printing and adjust as needed to correct any skewing.
  • Powder dusting: activate as needed to maintain sufficient powder on the film
  • Powder shaking: activate as needed to remove excess powder from the film
  • Oven temperature: maintain a temperature of 100-120 degrees Fahrenheit
    • Lean towards the higher end of the range for lower quality prints when the film is moving more quickly through the oven due to the higher print speed
  • Waste ink bottle: monitor the fluid level and empty before it exceeds 2/3 full
  • Ink bottles: Refill before the level drops to 1/2 full to maintain optimal ink flow and prevent air from entering the ink lines
  • Head cleaning: For optimal print quality, run a head clean every 10 full-size (approximately 12″x12″) prints, or a roughly equivalent amount of printing
  • Powder: If the powder dispenser supply is depleted, turn off the applicator rotation and recycle powder from the catch tray to the dispenser.
