Troubleshooting Blank Page Printing Problems with Epson L1800 Printers

Question

I have an Epson L1800 DTF printer that suddenly stopped printing colors. I performed multiple printhead cleanings, and the nozzle check shows that all colors are printing correctly. However, after printing one design successfully, the next print only showed white ink. What could be causing this issue?

Thank you for reaching out to us at BCH Technologies, and I apologize for the delayed response. We understand that all printer issues are urgent, and we want to address your concern with the detail and thought it deserves. We appreciate your engagement with our services and YouTube channel BCH Technologies YouTube Channel [https://youtube.com/@bchtechnologies]. Your feedback helps us improve our technical expertise and content.

Now, regarding your Epson L1800 DTF printer issue where only white ink prints after a successful design print, several factors could be causing this:

1. F1 Fuse Issue: The first step is to check the F1 fuse. If this fuse is damaged, the printer may still operate mechanically, but there will be no ink output, even if everything else seems normal. Replacing this fuse may restore the color printing functionality.

2. Clogged Printhead: Even though your nozzle check shows colors, the printhead may still be partially clogged. Sometimes, the cleaning cycles performed may not be sufficient to fully unclog the head. Consider performing a manual clean using a printhead cleaning kit to ensure there are no blockages.

3. Clogged Capping Station: The capping station is responsible for sealing the printhead and ensuring it remains moist, preventing clogs. If this station becomes clogged, it may not be providing the necessary suction during cleaning cycles, which could result in only white ink being printed. Inspect and clean the capping station if necessary.

4. FFC Cable or Mainboard Issues: The FFC (Flat Flexible Cable) connects the printhead to the mainboard. If this cable is improperly seated or damaged, it can disrupt the signal transmission between the mainboard and the printhead, resulting in a lack of ink output. Inspect the FFC cable for any visible damage and ensure it is securely connected to both the printhead and the mainboard.

5. Damage to the Printhead Membrane: Performing hard cleaning cycles, whether manually or through software (like the Power Clean function), can sometimes cause damage to the printhead membrane. This damage may result in a rupture or delamination, which can cause the printer to print blank pages even if the ink is flowing through the nozzles correctly. If this is the case, the printhead may need replacement.

6. Avoid Overuse of Ink Charge or Power Cleaning: Epson advises against excessive use of the Ink Charge or Power Cleaning functions as these place significant strain on the printer. If you need to run an Ink Charge, wait at least 12 hours before attempting it again. However, even with this precaution, there is still a risk of causing irreparable damage. I refer to this as the "Armageddon mode" because of its potential to cause serious harm to the printer. Use these options only as a last resort if all other troubleshooting methods fail.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. Therefore, we're unable to provide remote troubleshooting or support for printer repairs. We offer an in-person evaluation and repair service through our local diagnostic facility [https://bchtechnologies.com/printer-repair-service]. Given the high demand, we operate on a first-come, first-served basis, so there may be a few weeks' wait before you can drop off or mail in your printer. Our services include repairing the entire printer or specific parts, and we provide clear instructions on how to proceed if you choose mail-in or local drop-off options. We understand that our rates may not be the most economical, so we highly recommend self-help via online research. You can start by exploring our YouTube channel's homepage BCH Technologies YouTube Channel [https://youtube.com/@bchtechnologies]. Use the search icon next to "About" on the right-hand side of the menu bar to find relevant videos. Given the hundreds of videos we’ve created over the past nine years, this search function is the most efficient way to locate specific content. YouTube may also suggest helpful videos from other channels.
