Tip & How-To about Brother MFC 8440 All-In-One Laser Printer

Brother MFC 8440 showing error code MACHINE ERROR 6A or 6E

Hi.

Both errors are signalling a temperature problem in fuser assembly.

The solution below applies to several Brother models. Depending on the model, the reset procedure may be different.

Brother Error 6A means that the thermistor located in the fuser assembly did not detect that required temperature had been reached in valid time.

First you can try entering in maintenancemode and clearing the error. If that does not work, that means that the thermistor, the lamp, or the whole fuser assembly must be replaced.

Error 6E is similar. 6E is diplayed when thermistor detect that the fuser temperature is not going up at least at 2°C every for 5 seconds.

As for 6A, first reset the code. If the error does not clear the fault can concern the thermistor, the fuser lamp or the power supply to the fuser assembly.

To reset the error code follows these steps:

1. Press MENU *,2,8,6,4 . Press keys within 2 seconds.
2. The machine beeps and display shows “maintenance".
3. Look for Init or Reset on menu, and enter the corresponding parameter.
4. To exit press 99.

This procedure above usually works on MFC-8xxx model. On other models you may need to do the following:

1) Unplug machine.
2) Hold down menu key. Plug in machine.
3) Release menu key.
4) Enter 91
5) Enter 99

or:

1) Disconnect the printer power cord.
2) Hold down the menu key while plugging in machine at same time.
3) Enter 99 while holding down menu key
4) After menu says " wait" push the stop/exit button to get out of the maintenance mode.


If that does not work, it means that the fuser assembly must be replaced. Here the part for MFC-8440: Genuine Brother Mfc8440 Fuser Assembly.


Regards.

Ricoh Aficio SP 4210N- Code SC 543


This is a common error code for Ricoh copiers, Savin and Gestetner copiers that need service. Recently Ricoh has purchased Lanier and now is naming all their new machines Lanier instead of Gestetner, Savin and Ricoh. However, the copier service error codes have remained he same.
When you get this copier printer service code it means the fuser or fixing assembly (same part) has thermistor problem. The copier fuser's thermistors help regulate the temperature of the fuser assembly. The fuser assembly on all copiers including Canon, Kyocera, Ricoh, Sharp and other brands is the part that melts the toner onto the page.
Getting back to the repairing the copier on Ricoh, Savin, Lanier and Gestetner models that have the fuser or fixing code error. The majority of the time the fusers' thermistors (Middle and read) need to be replaced. Just cleaning them will not solve the copier repair service code.
It is usually, depending upon the machine, its a 1 to 2 hour copier repair job because the copier repair service technician will need to dissemble the fuser, insert the two new thermistors, re-assemble, reset the error code and test the copier machine repair. Also, ask the copier technicians to to do a copier cleaning maintenance while on site.

Wrinkled copies


Fuser unit is about the only thing in this model of printer that WILL cause wrinkling/creasing of the paper. So most likely, yes you are going to need to replace the fusing assembly.
