Should You Leave Your Procolored 1800 Printer On to Circulate White Ink? A Detailed Answer for DTF Users

Customer Question:
Is it necessary to leave my ProColor 1800 printer powered on to keep the white ink circulating? I’ve been keeping it on continuously for that reason.

Answer:

White Ink Circulation – Necessary

Yes, it is essential to keep the white ink circulation system and mixer running continuously. White ink in DTF (Direct-to-Film) systems is particularly prone to pigment settling. If left stagnant for too long, the white pigment can separate and form clogs inside the tubing, dampers, or, in the worst case, the printhead. Continuous circulation ensures that the pigment remains suspended, maintaining consistent ink flow and preventing costly clogging issues.

Do You Need to Leave the Printer Itself On?

No, you do not need to leave the entire printer powered on continuously, provided that you’re performing what’s called wet capping correctly. Wet capping involves sealing the printhead properly using a moist cap station or introducing a cleaning solution to keep the nozzles from drying out. If this is done correctly, the printer can safely remain powered off for extended periods without incurring nozzle damage.

However, ensure that your white ink mixer and circulation unit (often located externally from the printer’s main power switch) remain powered independently. Some systems allow the circulation pump to run continuously or on a timer even when the printer is off—this setup is ideal for prolonging printhead life.

Additional Considerations

• Automation: Consider installing a timer relay or smart plug that controls the mixer, ensuring regular circulation intervals even when you’re away.

• Shaking Ink Manually: If you’re not printing daily, shake the white ink cartridges or bottles regularly as a preventive measure, even if circulation is working.

• Daily Maintenance: Run a nozzle check every day. Even if you’re not printing, this keeps the ink moving and identifies clogs early.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Given the high demand, we operate on a first-come, first-served basis. So, it might take a few weeks before we can get your printer to drop it off. Our services are structured to repair either a whole printer or specific parts, with clear instructions on how to proceed. However, we acknowledge that our rates aren't the most economical. Thus, we highly recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage (https://youtube.com/@bchtechnologies). Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be most efficient. Plus, YouTube might suggest relevant videos from other channels that could assist you.

Thanks again for your question and continued support of BCH Technologies. We’re always here to provide the best help we can and hope your printer continues to operate smoothly!
