Brother Error Cover is Open — What It Means & How to Fix It
By Ryan Green · Updated August 2026 · Independent guide · PrinterCare USA LLC (not affiliated with any printer manufacturer)
This error appears on your Brother printer's display even though you can see the cover is completely closed and locked. It is frustrating because the printer refuses to print, scan, or function normally until it thinks the cover is properly secured.
The good news is that this is almost always a mechanical or sensor issue, not a software problem, and most fixes take less than 10 minutes to attempt at home. We will walk you through the most common causes and the exact steps to resolve them.
How to fix it — step by step
- Power cycle the printer completely. Turn off your Brother printer using the power button on the front panel. Unplug the power cable from the electrical outlet and wait a full 30 seconds. Plug the cable back in and power the printer on again. This clears temporary sensor errors and resets the cover detection circuit.
- Open and close the access cover slowly and deliberately. Locate the main access cover on your Brother printer, typically on the front or top panel depending on your model. Open it completely until it stops naturally, then close it slowly until you hear a distinct click sound. Push firmly on the cover to ensure it is fully seated and locked into position.
- Clean the cover sensor contact points. While the cover is open, locate the small plastic sensor switch on the inside edge of the cover or on the printer frame where it meets the cover when closed. Use a clean, dry cotton swab or soft cloth to gently wipe away any dust, paper fibers, or toner residue from the sensor and its surrounding area. Be careful not to bend or damage the sensor switch itself.
- Inspect the cover latch mechanism for damage. Close the cover and examine the latch and hinges visually for any cracks, breaks, or obvious damage. Look for bent plastic clips or hooks that should hold the cover in place. If you notice cracks or broken pieces, the cover assembly will likely need replacement through Brother support or an authorized service center.
- Check the sensor bracket alignment. Open the cover again and look at the small plastic bracket that holds the sensor switch. It should be positioned directly in line with where the cover makes contact. If it appears bent, pushed inward, or out of alignment, it may need to be gently straightened with a plastic tool or replaced entirely.
- Test with a thin object to trigger the sensor manually. With the cover open, look for the small protruding sensor switch or lever. Gently push or press it with a clean finger or plastic stick to see if you can manually trigger the sensor. If the error clears temporarily when you press it, the sensor is working but the cover mechanism is not fully compressing it, indicating a latch or bracket problem.
- Remove and reinstall the toner or drum cartridge. Open the cover and remove the toner cartridge or drum unit that is installed. Close the cover and check if the error message appears. If it does, the cartridge may be preventing the cover from closing fully. Reinstall the cartridge, ensuring it sits flat and clicks into its slots completely.
- Contact Brother support or schedule a remote repair session. If none of these steps resolve the error, the sensor unit or cover assembly likely requires professional replacement. You can reach Brother support for parts pricing or schedule a remote diagnostic session for forty nine dollars that may identify whether repair or replacement is needed. Many issues at this stage require factory service or parts shipment.

Frequently asked questions
Why does my Brother printer keep saying the cover is open when it is clearly closed?
The cover sensor switch has either failed, become dirty, or lost alignment with the closing mechanism. The printer cannot distinguish between an open and closed cover because the sensor is not being activated properly when you push the cover down. This is a physical hardware issue, not a settings or driver problem.
Will clearing the error by itself damage my printer or cause it to malfunction later?
No, attempting these fixes will not harm your printer. The sensor error prevents printing as a safety feature, but the printer itself is not damaged. However, if the underlying cover or sensor problem is not fixed, you will continue to see this error every time you power on or try to print.
Can I print anything at all if the cover error message appears on the display?
Most Brother printer models will not allow any printing, copying, or scanning functions while the cover error is active, even if you override or dismiss the message. The printer is designed to stop operations until it detects that the cover is fully closed and the sensor confirms this condition.
Should I buy a new printer or try to repair it if the sensor is broken?
Sensor replacement is usually affordable and worth attempting through Brother support before considering a new machine. The sensor bracket or switch assembly typically costs between twenty dollars and fifty dollars in parts and labor. If your printer is older or has other issues, you can request a quote before committing to repair.
