But the 440 seems to have a different cover arrangement so even after removing the screws to 'lift off' the top cover, it still doesn't want to budge. It looks like the whole cover wraps around the printer.

Re: Brother MFC-440CN Error 50
The cover on the 440CN is tough to get off. I have removed many. I will tell you that the cable from the scan (black mylar [plastic]) is fragile. I destroyed one of the printers by killing the connector end of the cable. That being said, on the 440 you have to remove the push button panel before the cover. There are 3 screws in the back. The cover then snaps off but feels like you are breaking it and it will snap as it comes off. I did not break this part on any of the printers so.... you should not worry too much. After that there are clips on the front that keep the top cover on. You must release these with a screw driver. You can insert the screw driver and twist. While twisting apply some upward pressure and it will release. You also have to remove a number of connectors, ground wire to get it apart.

WASTE TANK ALMOST FULL
or FULL ERROR MESSAGE PROBLEMThere is explained how to get rid of the error message very easy, and how to clean the waste ink pad manually. The latter seems not to be necessary, though.
1. Press CANCEL JOB to clear the print job from
the printer memory. 2. Turn the printer off, and then turn the printer
on. 3. Try printing a job from a different software application. If
the job prints, go back to the first application and try printing
a different file. (If the message only appears with a certain software
application or print job, contact the software vendor for assistance.) 4. If the message persists with different software applications and
print jobs, disconnect all cables to the printer that connect it to
the network or printer. 5. Turn the printer off. 6. Remove all memory
DIMMs or third-party DIMMs from the printer. (Do not remove the firmware
DIMM in the lowest DIMM slot.) 7. Remove all EIO devices from the
printer. 8. Turn the printer on. 9. If the error no longer exists,
install each DIMM and EIO device one at a time, making sure to turn
the printer off and back on as you install each device. 10. Replace
a DIMM or EIO device if you determine that it causes the error. 11.
Remember to reconnect all cables that connect the printer to the network
or computer. 12. If the error persists, replace the firmware DIMM.
13. Replace the formatter.
Dear KDBALANE, If you got this error-41 ,then its mean that Printer head is End of life. there is no solution for this error.is your printer in warranty or out of warranty? if this is in warranty then , contact to Brother , they will replace you printer .
**, it is not fixed. I followed instructions on Brother web site and was able to find a piece of paper near the printhead, so I removed it. The printer makes a grinding sound when it tries to print and the same paper jam error returns and can't be cleared. I beleive that the printer repair cost will be more expensive than replacing it with a different printer, and it won't be Brother brand. I probably would not be able or have the tools to do any complicated repair job.
