No need for part necessarily

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

Access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.
This will reset the purge count value. Then the printer will restart, try this step by step.without missing any thing. thanks

With some Brother printers you can try this.
Access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, and then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.
This will reset the purge count value. Then the printer will restart, hopefully without the annoying cannot clean message.
Some times this happens because of using cheap compatible ink cartridges if this is the case change the ink cartridges.
Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.
