The FreeJet 330-series of DTG printers has a Layer setting that is used to let the printer know if the print job sent to the printer is for a single color layer (for white shirts) or for two-layer prints, including a white underbase (for any shirt color other than white).
Single layer prints for white shirts should be run with the printer set to Layer ‘A’, while two-layer prints should be run with the printer set to Layer ‘B’.
The below video and following step-by-step instructions provide the details for changing the Layer setting.
Use the following steps to toggle the FreeJet 330-series Layer setting between the ‘A’ & ‘B’ settings.
Press and hold the Function button until the Status indicator light changes color and stops flashing.
Tap the Up or Down button to change the Layer setting.
Press Up to change from Layer ‘A’ to Layer ‘B’.
Press Down to change from Layer ‘B’ to Layer ‘A’.
Tap the Function button to save the Layer setting.
Use the recommended setting of ‘A’ or ‘B’ for the color of shirt you’re printing for the most efficient and trouble-free printing.
If you send a two-layer print job to the FreeJet when its Layer setting is ‘A’, simply tap the Stand by button when the printer has completely finished printing the white layer and becomes idle. Note that the Error light will be on, but the error condition will be cleared after you tap Stand by.
Properly mounting garments onto the platen is important to prevent movement of the garment during the printing process and ensure that your prints are straight with no distortion.
Use the patented TucLoc(R) feature to secure the garment in place, but avoid stretching the fabric when tucking it in. Printing on a stretched shirt can distort the printed design when the fabric is released from the platen.
The below video provides a brief overview of the mounting process.
Nozzle check test prints are used to determine whether or not ink flow is on track to deliver the outstanding print quality that OmniPrint products are known for. We use nozzle checks to avoid wasting consumable materials if the printer requires more preparatory steps before doing production work.
The below video demonstrates how to print a nozzle check test pattern on a Freejet 330-series printer.
Cleaning the printhead of Freejet printers is automated and can be done from the printer’s control or from its driver software. Running head cleanings is part of the production day startup process and is also useful to keep print quality high in larger production runs.
The below video demonstrates how to perform a head cleaning on Freejet 330-series printers.
White ink pigment is heavier than the pigment of the CMYK colors. Gravity will cause the white pigment to settle at the bottom of ink lines and bottles if the printer is idle for more than a day or two.
The below video demonstrates how to prime the white ink lines in a Freejet printer to flush out separated white ink and fill the white ink lines with opaque white ink to deliver a strong underbase and vivid colors in your prints.
The below video demonstrates the startup process for Freejet 330-series printers that are fully installed and already being used for production work.
This video includes a demonstration of the white ink circulation feature of the 330TX PLUS. This feature minimizes the need for priming the white ink lines for separation.
For both the 330TX and the 330TX PLUS models, it is helpful to shake the white ink bottles regularly to thoroughly mix the white pigment and to counter the development of sediment on the bottom of the white ink bottles from pigment settlement.
It’s recommended that this be done during the shutdown process, but if the printer has been idle for several days then it’s recommended to mix the white ink before starting up the printer, waiting at least 15 to 30 minutes before starting up so any bubbles introduced from shaking the ink can first dissipate.
When finished, use a clean cloth to wipe away any ink that appears to be blocking the breathing holes in the center of the bottle caps.
This video demonstrates and explains the initial ink line filling, priming, head cleans, and nozzle check test of a new printer.
Note that although the printer in this video has its ink lines full of ink at the beginning of the initial startup process, the directions are provided for a first-time startup of a new printer with ink not yet in the ink lines.
The Quick Reference Guide is a handy collection of information targeted to new customers, and it is also a great resource for more experienced customers who need a quick reminder of how to reach OmniPrint, the steps in starting up the printer, etc.
The Maintenance Log sheets are particularly valuable to anyone & everyone who uses a Freejet printer, to make sure the required preventative maintenance is being performed on the recommended schedule.
