How to Fix Epson L1800/DTF Printer Spitting Ink and Clogged Waste Tubes

Question:
My DTF 1800 printer is spitting ink, and I suspect the waste drain tubes are clogged. I've tried suction from both the back and top but had no success. I'm frustrated because I bought this printer second-hand, and the seller claimed it was only six months old-but I'm beginning to doubt that. Do I need to call or FaceTime for help to get it running again?

Answer:

From your description, the issue is not actually with the waste tubes themselves but with a clogged capping station. The capping station is responsible for sealing the printhead during idle times and for drawing ink through the head during cleaning cycles. When it becomes clogged, ink can back up, spitting out or leaking instead of draining into the waste tank.

Here are some key points and solutions:

1. Unclogging the Capping Station

   • The most common cause of backup is dried ink or debris inside the capping pad and tubing.

   • Flushing the capping station with cleaning solution can sometimes help, but if the clog is severe, you may need to remove and clean or replace the unit.

2. Installation and Maintenance

   • If you're comfortable with repairs, you can remove the capping station, rinse it thoroughly, and reinstall it. If the process seems too complex, especially since it involves partially uncasing the printer, it may be best to have a professional do it.

   • Once cleaned, regular maintenance is important to prevent recurrence. Keeping the capping pad moist with a cleaning solution and avoiding long idle periods will extend its life.

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 demand, we work on a first-come, first-served basis, and it may take a few weeks before your printer can be serviced. Our repair options include either full printer service or specific component repairs, with clear instructions provided for each. However, since our rates may not be the most affordable, we encourage self-help first. The fastest way is to search our YouTube channel (https://youtube.com/@bchtechnologies) using the search bar next to "About" for videos on your exact problem. YouTube may also suggest other helpful tutorials from the wider community.
