Question:
Your Epson WF-7610/WF-7620 uncasing video helped me. Do you have a video showing how to change the circular encoder?
Answer:
Thank you for contacting BCH Technologies, and I apologize for the delayed reply. Printer problems are urgent, and we want to give you a careful, detailed answer before suggesting disassembly. Thank you for supporting BCH and our YouTube channel.
I cannot confirm a BCH video that shows the circular encoder replacement for your exact printer. The video linked to your question covers uncasing the Epson WorkForce WF-7610 and WF-7620. Please confirm which model you have before following a replacement procedure, because access, part positioning, and reassembly details can differ. The circular encoder disc is part of the paper-feed position sensing system, but your question does not include an error code or symptom that would establish the disc as the failed part.
Before buying an encoder, turn the printer off and unplug it. If you are comfortable opening the printer, inspect the disc and its nearby sensor for visible ink, dust, scratches, a bent edge, or a disc that is rubbing or sitting outside the sensor slot. Keep the printed markings clean and dry. Do not touch them with oily fingers, scrape them, or apply lubricant. Use only a model-specific service procedure for removal, and photograph cable and gear positions before disturbing them.
A dirty or misaligned disc, a sensor issue, or a cable or drive problem can produce similar paper-feed symptoms. A replacement encoder will not cure a damaged sensor or a mechanical bind. If the printer is showing an error, send the exact model, the complete code, and when the fault appears. That information can narrow the checks before you remove the paper-feed assembly. If the disc is damaged or the fault persists after safe visual checks, a technician can inspect the encoder alignment and sensor and decide whether parts or board-level diagnosis are needed.
Search the BCH Technologies YouTube channel [https://youtube.com/@bchtechnologies] for "WF-7610 PF encoder" or "WF-7620 circular encoder" and compare the demonstrated model with the label on your printer. For help with a difficult teardown, contact BCH Technologies about repair service and include photos of the printer label, disc, and sensor area.
