20 Most Recent Brother MFC-8480DN All-In-One Laser Printer Questions & Answers

Error 78 indicates a mechanical malfunction from within the printer. Not6 really anything you can do as the end user. I would recommend getting in touch with Brother or a printer technician.

I am a technician for brother printers. Yes it is your drum unit that is printing the grid on the unit. go our web site www dot tonerconcepts dot com and place an order for a drum from us. The drum your machine uses is the DR520/620 Our online price is $120.00 with free shipping

The FIXYA ****, as usual is just 'that' - **** - it has instructions for MILLIONS of different printers and they are just trying to sell Advertising - so you have to WADE THROUGH S**T to get to the real answer, which often is WRONG - as in this case - on Fixya, the instructions, when you search for "drum error 8480dn" say "Open the front cover and press the Options button and choose Yes to the prompt about replacing/resetting the drum" - only there IS *NO* OPTIONS BUTTON ON THE 8480DN model - instead,

Open the front cover.
Press the Clear/Back button AND the Menu button at the same time
Choose "Yes" when prompted to replace/reset the drum life count
Close the front cover.
Done!

Even BROTHER DOES *NOT* HAVE THESE INSTRUCTIONS, because they hope you do what we have been doing - see these continual DRUM ERRORS and then just REPLACE THE *ENTIRE* PRINTER! This is CLASS ACTION LAWSUIT material against Brother! Let's sue them! Thanks.

hi. this is all i could find,go to this link and the bottom of the page if you need more help. Microsoft has a printing troubleshooter that can help to identify problems.

There are periodical parts to be replaced - eg. laser, fuser & PF Kits. You can check from your display which is due. You can also reset the counter to continue using if printer/printout is normal by going to maintenance mode & 8, 8 , choose which counter to reset.

on most printers you have to reset the paper thickness for envelopes or it will read a jam

Hi, sounds like the settings were altered. I would suggest resetting the machine back to factory settings. You will lose all settings unfortunately (address book, network settings..) Press menu> 0,6, then ok, then choose reset> ok. Then choose yes then ok to reboot machine. Hope that helps.

Could be toner life end or laser unit is weak.
