Brother Printer Error Code 22: How to Fix It

Q: Why does my Brother printer say cover open when it is closed?

This usually happens because the small plastic tab on the cover that presses the internal sensor is not making proper contact. It can be caused by debris buildup around the latch, a slightly warped or misaligned cover, a worn actuator tab, or a faulty sensor. Try opening and firmly re-closing the cover until you hear a click, and clean around the latch area with compressed air.

Q: Can I print with Error Code 22 on my Brother printer?

No. Brother printers are designed to stop all print functions when Error Code 22 is active because it indicates an open cover. This is a safety measure to protect both the user and the printer's internal components. You must resolve the error before printing can resume.

Q: Which covers trigger Error Code 22 on a Brother printer?

Depending on your Brother printer model, Error Code 22 can be triggered by the front cover, the ink cartridge or toner access cover, the drum unit cover, the rear paper feed access panel, or the duplex tray cover. Check every door and panel on your specific model and make sure each one is firmly closed.

Q: How do I fix Error Code 22 on a Brother laser printer?

On Brother laser printers, the most common cause is the front or top cover not being fully latched, or the toner cartridge and drum unit not being properly seated. Open the front cover, remove the drum and toner assembly, reinsert it firmly until it clicks, then close the cover with even pressure until it latches. If the error persists, inspect the cover sensor tab for damage or debris.

Q: Is there a cover sensor replacement part for Brother printers?

Yes, cover sensor switches and actuator tabs are available as generic replacement parts for many popular Brother printer models. To find the correct part, you will need your exact printer model number, which is printed on a label on the bottom or back of the printer. Search for your model number along with 'cover sensor' or 'cover switch' to find compatible parts. If you are not comfortable replacing internal electronic components yourself, have a technician do the repair.

Abstract

Brother printer Error Code 22 means the printer has detected that one or more of its covers or access panels are open or not fully latched shut. The printer will refuse to print until all covers are securely closed and the sensor confirms they are properly seated. This is a safety feature to prevent printing with exposed internal components, but it can also trigger when a cover latch, hinge, or sensor is dirty, damaged, or misaligned.
