For the error code "7a" to be fixed permanently, you need to ensure that the main PCB is fine and is working in good condition.
If the error code is caused due to malfunctioning of the main motor, then you need to check the whole setup by connecting it with another motor.
In this case, make sure that there is no mechanical load present on the main board.
While fixing this error code, you will notice that the motor runs slowly initially and then picks up the speed later.

Just installed a new drum unit in my Brother DCP1000, and it's still reading "Replace Drum soon"


heya!
this stands for brother mfc-8440 as in the title.
you need to reset the "drum counter" of your printer..
to do so try one of those

Brother Laser Printers:

After replacing the drum unit, keep the front cover open (make sure the power is on). Press and hold the "GO" button until all four LED's are lit. Once the four LED's light up, close the front cover. Make sure the drum LED is off. The counter is reset!

Brother Fax Machines:

Open the front cover. Press the CLEAR/BACK button. Press 1, when the display shows accepted.

Brother MFC-8440 Machine Error Code 7A - tried to print something and machine stopped, beeped and gave me this code. No resolution from Brother other than to have a tech come look at it. Any insight...


Hello thanks for using FixYa
Error code 7A occurs in different forms and they are linked directly to errors caused due to calculations as detected by GPU, however, it is still doubtful what exactly cause these GPU errors in hardware and the errors in WU. Keep in mind that this error code could also suggest that the main PCB is broken.

For the error code 7A to be fixed permanently, you need to ensure that the main PCB is fine and is working in good condition. If the error code is caused due to malfunctioning of the main motor, then you need to check the whole setup by connecting it with another motor. In this case, make sure that there is no mechanical load present on the main board. While fixing this error code, you will notice that the motor runs slowly initially and then picks up the speed later.

Canon fax machine says "cover open" and won't do anything till the msg is cleared. How do I clear this msg when my cover is in fact closed?


You may need a new hinge, the one in the left rear breaks and gives that error when the scanner cover doesn't go all the way down. the hinge is part #
LP2403001.
