How to Fix Back Cover Open Error Message From Brother DCP 7020 Printer

Answering a readers request to solve the following Error problem: "My Brother DCP 7020 laser printer won't work. It keeps saying the back cover is open, please close it. But the cover is closed! What's up with that? "


If the Brother DCP 7020 was turned off and then turned on again with a paper jam in the back of the machine, you’ll find a message in the LCD saying: “Back Cove Open”. So in order to solve the problem follow this steps:




Step 1: Open the front cover
Step 2: Pull out the drum unit and toner cartridge assembly.
Step 3: Open the back cover.
Step 4: Pull the tab toward you to open the rear chute cover.
Step 5: Pull the paper jammed inside out of the fuser unit. If by any chance it cannot be pulled out easily, push down the tab with one hand as you gently pull out the paper with the other hand.
Step 6: Close the back cover.
Step 7: Insert the drum unit and toner cartridge assembly back inside.
Step 8: Close the front cover.


This should clear the error message, but in case it is not power off the Brother DCP 7020 laser printer.

Note: This message may appear even if you don’t have a paper jam. The reason is that you probably installed a new toner cartridge or drum unit wrong. So reinstall your toner cartridge and or drum unit properly.


However obviously that might not clear the problem completely so here is another thing you can try….

There is a black guide plate that opens partially when you open the back door, there's a sensor flag on that cover that goes through the right side to a sensor, the arm on the guide needs to move freely, and the flag on the right must pass through the sensor inside a hole on the right... so go back to the back door and try to look for the sensor, it has a small lever that goes back and fort check if it is not misaligned.
