Brother MFC 5840CN "Unable to Clean" Message

Orion,

Thanks for your posted insights on this machine....I cleared out the purge counter per your suggestions....and still have the error code message.

How do you disassemble the machine to get to the purge box to accomplish the following:

Comment by orion, posted on Aug 27, 2008 Your purge box is nearly full. You can remove it and rinse the sponges with water until they run clear, let them dry, and reinstall. The procedure that I listed above resets the counter. Comment by orion, posted on Aug 27, 2008 Be sure to put tape over the top of the purge box were the plastic is to prevent ink splatter. I really appreciate your help and any suggestions here!

    Machine was working fine and then all f a sudden the "unable to clean" message stated appearing in the LCD display.



    What options to repair myself do I have before trashing the unit and buying a replacement?



    Thanks for your help.

    I have the same problem.  Was printing happily then "unable to clean" message appeared.  Tried cleaning the white runners and glass etc as directed.  Checked no paper stuck.


    Don't know what to do next.  Don't want the get the engineer in.  Costs more than a new printer would.  Shame to bin it though.


    Please save my hair.  I am pulling it out.

My brother 5840CN. lit says unable to print. the manual says to take the jam out - there was no jam. Turn it off, then on. i did that. It still says unable to print, look at troubleshooting page


errr.....No, no it does not. The Manual says that "unable to clean" means one of two things.....
1. The MFC has a mechanical problem.-OR-2. A foreign obstacle, such as a clip or ripped paper, is in the MFC.
but regardless, I don't believe it *IS* a 'cleaning' problem per se.Try resetting the power purge counter.



Press menu > Mono Start > 4x Arrow up after another. All lights will flash.
1. Power clean - Press 7>6>4 >Mono? Start.
2. Power Purge: 7>6 >3 >Mono Start.
Press 9>9 to exit maintenance mode. Run a print quality test print.

Mfc 5840cn problem


Machine Error 46 – Purged Ink Box Full MFC620CN/420CN/410CN/210C and FAX2440C

The machine counts all purge (cleaning) operations in order to prevent the internal ink absorber box from overflowing with purged ink. An “initial purge”, for example, advances the purge counter by 187 + 420 = 607. When the purge counter approaches 6400, an internal "Machine Error 46" is generated. Further purge operations are prohibited, and therefore the printer becomes unuseable.

When an internal Machine Error 46 is generated, the user will see an “Unable to Clean” external message and will be unable to use the printer. The “Unable to Clean” external message can relate to many different internal error codes however.

The user can establish the internal Machine Error Code as follows: pull the mains cable out of the machine (power off), hold down the Menu/Set key, re-insert the mains cable into the machine (power on). The internal Machine Error Code will be displayed.

If there is a Machine Error 46, it is necessary to dismantle the printer, replace the ink absorber box (or possibly break the ink absorber box open and clean its absorbent sponges under a tap), re-assemble the printer and reset the purge counter to zero.


Resetting purge counter MFC620CN/420CN/410CN/210C and FAX2440C

1) Enter machine maintenance mode (on MFC210C all four photo/copy/fax/scan lights flash in maintenance mode). Care is needed in maintenance mode, otherwise critical settings may be inadvertently corrupted.

FAX models with numerical keypads: Press the Menu/Set, *, 2, 8, 6 and 4 keys within two seconds. (if you fail to complete the correct key sequence within two seconds, press the Stop key to try again).

Other (non-FAX) models: Press the Menu/Set and Black Start keys. Next press the “up arrow” key four times to enter the maintenance mode).

2) Press the 8 then 0 keys in the initial stage of the maintenance mode to call up the machine's log information list (function code 80).

3) Press the Black Start key several times to scroll through the log information list to reach the purge counter. The purge counter is the 25th item in the list.

4) Press the 2, 7, 8, and 3 keys in this order to reset the purge count to zero.

5) Press the Stop/Exit key to return to the initial stage of the maintenance mode.

6) Press the 9 key twice to return to the standby state.

Carry on printing !!

Unable to clean


Hi lobispo41,

If you are getting "Unable to clean" message from your Brother printer kindly refer on the steps below to address the concern:

1. Turn off the machine.

2. Turn the machine ON while you are pressing the MENU button. wait until leds flash. This time you're on maintenance mode.

3. Press 80.

4. Then, press MONO START button until you see "purge:xxxx".

5. Afterwards reset the purge counter by pressing 2783. Purge:0000 will appear.

6. Press STOP button.

7. Finally, exit the maintenance mode by pressing 99.

You can now go ahead and use the printer once again. The prompt should be gone after doing these steps.

Hope it helps.

Thank you for using FixYa,

My Brother MFC-5840CN.Is showing Unable to clean


Mechanical problem with the machine.
The purge unit needs to be replaced.
Check www.brother.ca and you can find a service center.

The repair is at least 50$, may not be worth repairing.
I recommend looking for another inkjet on sale and just replace this one

The ink absorber box and the flushing case will need to be replaced. Then the purge counter and the flushing counter will need to be reset to 0.

Error 46 Unable to Init.


No need for part necessarily
SkipperOz solution pasted below

MFC-5440CN saved from the tip!
"Unable to Clean" message - found TrickyDicky's sltn 4 for various printers.
Went into maint mode as per sltn 4 - verified error 46.
"The user can establish the internal Machine Error Code as follows: pull the mains cable out of the machine (power off), hold down the Menu/Set key, re-insert the mains cable into the machine (power on). The internal Machine Error Code will be displayed."

Keyed in 80 - stepped through the items with "down" key and located Purge Counter.
"Press the 2, 7, 8, and 3 keys in this order to reset the purge count to zero
Press the Stop/Exit key to return to the initial stage of the maintenance mode.
Press the 9 key twice to return to the standby state."


This worked brilliantly - no need to tamper with any parts of the printer. Purge Counter reset did it all. Fully functional printer.

Thanks TrickyDicky for info on verifying the error code and purge reset
