Maintenance Recommendations for Your CORVUS RR330DTF Printer

Desktop DTF (Direct-to-Film) printers are frequently used in the textile and advertising industries. Regular maintenance is essential for these machines to operate efficiently over time. Here are some crucial tips for long-term precise and efficient use:

1- Continuous Ink Flow:

It’s vital to maintain a continuous flow of ink from the print head; DTF ink can become elastic if it remains static for some time, leading to clogs and irreversible damage. To prevent this, it’s necessary to print daily. If you can’t print daily, you should print a test page with all CMYK colors on tracing paper every day. If any issues are noticed during the test print, the print head should be cleaned immediately.

2- Lubrication and Cleaning:

For efficient operation, the machines should be lubricated and cleaned at certain intervals. This is especially important for printers since cleaned and well-maintained machines produce more precise and high-quality results. You can follow these weekly maintenance tips to avoid any decrease in print quality:

– Unlock the print head and switch it to free mode.

– Lubricate the felts on the right and left of the print head (at the points where it connects to the metallic-colored shaft that allows it to move) with WD-40. Be careful to only lubricate the felts and wipe away any excess oil with a tissue. After lubrication, move the print head back and forth 3-4 times.

– Move the head to the far left, clean any residual ink around the cleaning unit located under the head on the far right. During head cleaning, use a plastic tool to remove and dry the rubber piece that scrapes the ink off the head.

– Tear off two sheets of paper towel, dampen the tip with a little isopropyl alcohol, pull the head from the left to the center, and wipe the bottom of the head with the alcohol-dampened towel.

– Move the head from the center to the far right, clean the transparent encoder strip above the shaft and the yellow belt with a soft glasses cloth, and repeat this process by moving the head to the far left. (The encoder strip helps determine the position of the head during printing; if the strip has ink or oil on it, it should be cleaned with isopropyl alcohol.)

– The waste ink tank should be emptied weekly. The best method to dispose of the ink is to pour it into plastic bottles and throw them in the trash. If you do not empty the waste ink tank, the system will shut down when it’s full and will only restart after the tank has been emptied.

3- Ink Level Checks:

Depending on usage intensity, ink levels should be monitored; a decrease in ink levels could cause air to enter the dampers.
