Restore proper cover detection with the GC Original Access Cover Unit Switch (Part No. QM8-0763) for Canon MAXIFY GX3000 and GX4000 series printers.

Refurbished/pulled original cover switch unit, tested before dispatch — a reliable, cost-effective repair solution.

📝 Product Description

The GC Original Access Cover Unit Switch – Part No. QM8-0763 is a replacement part designed for the Canon MAXIFY GX3000 series and GX4000 series printers.

This switch detects whether the access cover (used for ink tank refilling or maintenance access) is open or closed, communicating this status to the printer’s control board. The printer relies on this signal to know when it’s safe to operate the carriage and print mechanism.

A faulty or misaligned access cover switch can cause a persistent “cover open” error even when the cover is closed, the printer refusing to start a print job, or the carriage failing to move properly.

Replacing the access cover unit switch restores accurate cover detection and normal printer operation.

Value For Money — Pulled from a working printer and tested before dispatch, offering a cost-effective alternative to a brand-new switch.

7 Days Warranty

Ideal for printer technicians, service centers, dealers, and printer repair professionals.
