Question about Brother MFC 420CN All-In-One InkJet Printer
See Troubleshooting and routine maintenance chapter in User's Guide.
I have done everything twice that it says in the User's Guide and it still will not work.....HELP!
Machine error 46 ("Unable to Clean") indicates the wasteink "sponge" as full, which disables the machine's ability to clean. To fix this, you could get the needed part from a Brother parts dealer and enter the servicemode to reset the counters. However, the more reasonable thing to do would be to just change to another machine. You could also have the machine sent to service, but that most likely would not be worth the trouble. The error is pretty common on old Brother inkjets, so it'll come back eventually even if you replace the part. Newer machines should not have this problem.

Testimonial: "Thank you for the site info! i looked for a long time, wish i had asked and followed your advice the first thing as it went right to it."
Unable to clean means the ink absorber box is full. You will need a shop to replace the waste ink absorber box and then reset the waste counter in service mode.

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.
