Question about Brother DCP-7065DN

Open Question

How to clear the error "print unable 7A" and "print unable EC"?

Scenario 1: We have (1)one machine with a physical damaged drive motor. We bought a replacement and installed it. After switching it on, an error appeared "print unable 7A". We've done Step 1-3 except Step #4, based on the service manual SM_HL2280DW_DCP7060D_DCP7065DN_MFC7360N_MFC7460DN_MFC7860DW.pdf Scenario 2: We have another machine with no problems, with no errors on it. Good as new! We tried to replace the PCB board from the machine stated on Scenario #1, using the PCB Board of the machine from Scenario 2 then an error disappeared. So we returned the working PCB back to its original state. It should work right? It didn't as expected and an error appeared "print unable EC". Both machines are now having different error codes. Machince on Scenario 1: "print unable 7A" Machince on Scenatio 2: "print unable EC" Is there way we can clear this error? Thanks in advance!

SOURCE: error message print unable 50

the encoder strip which gives the printhead the position is out of place (error 50). You have to open the printer and reinsert the strip:

Stick a 1.5 inch tape onto the printhead cover where the strip runs thru. This will prevent this accident in future!

The printers memory may be full depending on the type of documents they are printing. The first and most simple step is to unplug the power cord from the back of the unit for 30 seconds, put your finger on the stop key while plugging the unit back up and continue holding the stop key until the time and date are back on the display of the Brother unit.

If that does not work unplug the USB cable from the PC. Unplug the power cord from the unit again. Put your finger on the menu key first and then plug the unit back up. You want to hold the menu key unit the until the LCD says maintanence and all the lights are flashing. Let the menu key go and press the number 82 and will give you an error code. If the error code is 00 then there are no errors. If there is an error code record it and contact brother or check a service manual if you have one. Most laser products all have the same error codes with Brother.

To reset the unit press stop and then 91, this will reset the unit and all faxes or print jobs will be lost. This should clear the issue.

If it is on copying it can be a build up of ink on the scanner glass. Open the cover in which the the original is scanned. There will be glass strip that can be cleaned also check the white plate that sits above the scan glass.

If it is recieved faxes and prints as well the problem is going to be the drum has worn out. You have two machines, try interchanging the drums to see if the lines that are present on one machine travels to the next. That way you can see if it is definately the drum. If so change the drums on the machines and they should be fixed.

Machine error 7a on brother mfc8640d


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.

KENMORE HE2T WASHING MACHINE


"F25" is a tachometer error. If the control unit is unable to detect the proper motor speed, the machine will shut down. You can attempt to unplug the washer for at least 30 minutes to reset the computer. Sometimes this is all that is required to correct momentary glitches. If the error reappears, the manufacturer recommends the following:

1. Check the wiring harness between the Central Control Unit, Motor Control Unit and Drive Motor to ensure they are all connected properly and not broken or loose. This would be connections L2 and N1 at the MCU and connector MS2 pins 1 and 2 at the CCU. (There is a wiring diagram inside the washer behind the lower kick panel).

2. Verify the Drive Motor is turning and the motor windings are good. Resistance checks at the drive motor connector acros Pins 1 to 2, 2 to 3, and 1 to 3 should all read about 6 ohms.

I hope this helps you.

PS I believe the tachometer is a physically attached to the drive motor.
