Did you change the toner cartridge with a new genuine oem cartridge?
Do a report print <settings> page from the menu and check the 'Drum life' Bar graph. If close to, or at 0%, get a new Drum unit

Text missing when document is printed from Brother MFC-9840CWD


Hello,This issue may becaused by poor connection. Check to see if all interface connection cables arein the printer. If the printer doesn't establish good connection with thecomputer print quality will decrease.Second thing you can check are thesettings on the computer. Are they matching with settings in Brother MFC-9840CWD.This is issue is not caused from the toner cartridge or drum unit.

Printer gives warning that toner life is gone. I replace the toner twice . Each time it prints one page and then gives error message. Page that did print out has dark horizonal lines.


Check the toner cartridge, side gears, you can see a reset lever (that lever is very important) show in the next picture.(cartridge new)

Brother MFC-9840CDW not printing colours properly


Always use Brother toners. This is a common issue with cheap copies and remanufactured cartridges.

I have a Brother MFC 240C printer that will not print black ink. I just changed all the cartridges. All the other cartridges print. I ran the clean cycle many times. No error messages just blank paper.


I have a brother MFC 3240C. My Black ink stopped printing(initially printed horizontal faded lines and gradually got worse), the other colors were printing fine. I tried cleaning numerous time( 50 -100 times over 1-2 weeks ). Still no improvement. The way I print now is:
1. I go to Printer Properties
2. Change Media type from "Plain Paper" to "Inkjet Paper".
3. Change Quality to "Photo".

This takes a long time to print 1-2 minutes per page. However, this works for me since this is my Home printer and use it for printing only few pages here are there.

Good Luck

Brother 210C One colour cartridge empty, want to print a black and white fax


Yes, if you dont need the color anymore in future:

You can cheat with empty c/y/m carts by sticking some dark but very thin adhesive tape around the nose (see picture).

After that the printer logic expects the c/y/m carts always as full.

But you cant print any colors within the next 2 weeks anymore because air will dry out the print head (and destroy the color nozzels)!

See brother homepage for instructions on how to print in grayscale only!
