Epson WF-7710: Fixing the 'Cover is Open' Error: Glass Blocked Sensor Compatibility and Solutions

Question:

An Epson WF-7710 printer occasionally shows a 'Cover is Open' error on the LCD screen. I came across the Epson Cover Open Sensor for WF-3640 (https://bch-youtube-fan-store.myshopify.com/products/epson-cover-open-sensor-for-wf-3640) and wanted to know if it would be compatible with my WF-7710. If not, do you have the proper part for this printer?

Answer:

Regarding your question, the 'Cover is Open' error can very well caused by a defective cover open sensor on the Epson WF-7710, but there are a few other possibilities:

Possible Causes and Fixes:

Faulty Cover Open Sensor:

A faulty sensor for opening the lid could also be to blame! If this is the problem, the error will be resolved when the sensor is replaced.

The WF-3640 sensor will not work with the WF-7710. Unfortunately, we do not currently have the exact cover-open sensor for the WF-7710, but it can also be sourced from third-party suppliers.

The wire is broken, or the connection is loose:

If there is a short wiring between creating a connection to the sensor, sometimes it can lead to a broken or loose connection, producing intermittent errors.

Examine the wiring for any apparent damage and ensure all connections are tight.

Damaged Pin on the Mainboard:

If the sensor and wiring look alright, the problem might be with the mainboard connection.

If the mainboard pin reads the sensor is damaged, replacing the sensor will not work.

Next Steps:

• If the sensor is faulty, obtain a WF-7710-specific cover open sensor from a trusted supplier.
• If you suspect wiring problems, carefully re-seat or remove any damaged cables.
• If the mainboard is bad, then you'd need a much more sophisticated repair.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we cannot 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).
