How to Replace the 9-Pin CISC on Epson Workforce C-5710 and C-5790

Q: How do I replace the black ink 9-pin CISC (PPO-EP-CSIC-9PIN) on the Epson Workforce C-5710, given the pins seem out of alignment? The C-5790 model seems to have a similar setup, as indicated in the picture I provided where the affected pins are pointed out.

Addressing the issue with the 9-pin CISC on the Epson Workforce C-5710 (and similarly on the C-5790), it's important to carefully handle the replacement to ensure proper function and recognition of the black ink cartridge. The pins you've mentioned are crucial as they connect the printer to the cartridge, enabling ink level detection and proper printing functionality.

The pins include tabs or "hooks" on both sides that secure them in place. Although I don't have direct access to a C5710 model for a hands-on demonstration, the general approach to resolving pin misalignment involves carefully applying force to adjust or replace the pin assembly. Based on the assembly image you referred to on our site (Epson Cartridge Chip Board Pins), you'll notice an arrow or hook on the lower left side. This is the tab that keeps the pin secured.

If working on this assembly vertically, I recommend finding a way to stabilize the bottom part of the assembly. Then, gently jiggle the assembly forward with your finger, aiming to release the hook. I will rock the assembly back and forth while maintain upward pressure from beneath, which should help the assembly to pop out. This method allows you to replace or realign the pins without causing further damage to the printer or the cartridge chip board.

Addressing printer issues, especially those involving delicate components like the 9-pin CISC, can indeed be complex. Each problem, from a simple clog to a "paper jam," has its unique set of potential causes and solutions. While we are committed to providing support through our resources at BCH Technologies, including detailed guides and video tutorials, certain situations require more direct intervention.

For hands-on assistance, we invite you to our local diagnostic facility for an in-person evaluation and repair service, available through BCH Technologies Printer Repair Service. Please understand that due to high demand, we manage requests on a first-come, first-served basis.
