Question:
I recently acquired an Epson WF-3540 printer that was labelled as non-functional. After cleaning it thoroughly and replacing the printhead, the printer still produces blank pages despite the ink levels dropping during priming. It also displays a CxC0 error and intermittently fails to recognize the black cartridge. Could this be due to a faulty E6754 mainboard, or is there another underlying issue?

Let’s break down your issue and explore potential solutions:
Diagnosing the Problem
-
Blank Pages Despite Ink Usage:
The dropping ink levels after priming indicate that the ink is reaching the printhead but is not being dispensed onto the paper. Possible causes include:
- Clogged Nozzles or Ink Lines: Even with a new printhead, dried ink in the ink lines or dampers can restrict ink flow. Could you look over the lines with a flashlight for obstructions?
- Air Leaks in the System: Air bubbles in the ink system can cause priming to fail.
-
CxC0 Error:
This error often stems from a communication problem between the printhead and the printer’s mainboard. The likely culprits are:
- Faulty CSIC Board: Check the board for visible damage, such as burnt areas, corrosion, or poor contact points.
- Damaged Ribbon Cables: Ensure the cables connecting the CSIC board to the mainboard are intact and properly seated.
-
Black Cartridge Not Recognized:
If the black cartridge is repeatedly unrecognized:
- Cartridge Compatibility: Even new cartridges can occasionally be defective. Test with another cartridge to rule out this possibility.
- Cartridge Slot Contacts: Clean the contact points with isopropyl alcohol and a lint-free cloth. Verify that the spring-loaded pins in the slot are operational.
Suggested Fixes
-
Flush the Ink System:
Residual ink from previous use might clog the system. Use a syringe and tubing to manually flush the ink lines and dampers, ensuring they’re free from obstructions. -
Manually Prime the Printhead:
A vacuum tool can help pull ink through the nozzles, ensuring an even flow. -
Inspect the Cartridge Slot:
You can temporarily swap the black cartridge for another colour cartridge. If the black slot works with a colour cartridge, the issue may lie with the cartridge rather than the slot. -
Evaluate the CSIC Board:
Cleaning the CSIC board was an excellent first step. Double-check for bent pins, loose connectors, or any physical damage. -
Consider the Mainboard:
If all else fails, the E6754 board (part of the mainboard) could fail. This would require sourcing a replacement and might involve advanced technical skills or professional help.
