    My printer was working fine then, my yellow said it was low, which I replaced; also it said that it was unable to print to check troubleshooting and maintenance in my manual. I cannot get it to acknowledge that there is a new yellow I am at wits end. It wont clean or anything

    My printer also says "Unable to Clean...See Routine Maintenance Section in Owner's Manual." I have completed every cleaning method in the section and it still does not work.

    My Brother MFC 420cn will not print. the LCD read-out states "UNABLE TO PRINT" and directs to "see user's manual".. suggestions there are useless. I've checked for obstructions, jammed paper, and even powered down for 5 minutes...
    Anybody else have any ideas?

  • rachaelpaint Mar 30, 2009

    Same problem. I'd like to know the solution so I know whether to spend $ to get a new printer of it's a cheap fix.

You need to reset the Purge Counter.

To reset purge counter
1) Enter machine maintenance mode (on MFC240C 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.

Problem with my printer Brother MFC-240C "Print unable 4F"

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
