My printer Brother MFC-420CN keeps showing the message, "Unable to Print," after it completes the start-up cycle. I'm able to use the Scan and Copy functions from the printer, and have whatever I scan or copy from this printer, printed out immediately on another printer connected to my computer. But I still can not print anything on my MFC-420CN. I went online and found a free service manual for the model MFC58 and learned how to put the printer on maintenance mode. I was able to get an error code, but since the manual is for the model MFC580 I was not able to learn the meaning of the code. The error code is 5A. Please any assistance with this matter will be greatly appreciated. Thank you.
I ham getting an "unable to print" message whenever I try to do anything, even turn the printer on. Prior to this there was a paper jam. What do I do?

I often have the same problem - The inks being put into the printer are seated very sensitively. The lever holding them in may be also acting as a pressure sensitive switch because when I wiggle it a little, the printer usually starts working again! Make sure the cartridges are pressed STRAIGHT DOWN, wiggle them and wiggle the plastic pressure lever. (I do not know what else to call it!) and I hope yours works again. It is a great little printer, but this is really annoying! Good luck!
BTW, if your inks are RE-FILLED, that may be your problem. It seems they are made to NOT be refilled. To avoid this problem, do not wait till they are empty to refill them. Check them monthly (depends on usage) and when they get 1/2 way, refill then. Do NOT put the hypodermic refilling tube in deeper than necessary to refill. I use a heated nail to make my hole in the plastic, going ONLY in as far as necessary to make the hole, and then I cover it with scotch tape. Then I wash off my hands with Lava soap! (Haven't mastered the knack of not getting the ink on myself, yet!)
Do you mean "unable to clean"?If it this follow this instruction. Unplug the printer from power cord.Press and hold the "menu" button, then plug the device.You'll see on the LCD screen a "machine error" code.If this code is 40,41 or 4F the print head is defective.If the error is 50 or 51 there is error in Purge unit and printer require service.If the error is 46 the waste ink tank is full.Follow this:Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If numberis over 6000, enter 2 7 8 3.This will reset the purge count value. Then restart the printer, hopefully without the annoying cannot clean message.
