If you are using a generic toner, replace it with cartridge from Brother. Many of these are caused by using a refilled cartridge or a generic cartridge. Use a cleaning sheet and run it though a couple of times, if this does not clear it up you need a new cartridge.

Are the supplies you are using OEM ( original equipment manufactured ).... or is it remanufactured? I've had issues with some of the remanufactured products ( or rebuilt ). I would also take the toner out and inspect the paper path for toner and clean it out with a 3m vaccuume and a lint free wipe. Other than that it might need a new fuser.

Hi, this error shows when the corona wire is dirty, some times I clean the corona wire with a small screw driver pressing the corona wire down and slide the screw driver to the both sides also once you clean in the up I press from the side and slide the screwdriver after that with a cotton swab with isopropyl alcohol slide from side to side, or replace the drum unit and reset, if you install a new toner, there is a mechanic control for reset the printer toner counter, this only works the first time that you install the cartridges, for example If you install the cartridge in 1 printer and then move to other printer the other printer keep the counter for the old cartridge, if you are sure that your cartridge is new you need to open a return the gears to is original position in order to install in another printer.

you can try to clean the pick up rollers with a piece of cloth with isopropyl alcohol, if that don't work you need to replace the pickup roller , it cost about 20 dollars

f it's not doing this to a regular plain paper, then you need to tell the printer you're printing envelopes. Envelopes are thicker than letter paper. When you tell it to print, make sure you click on "Properties" and set the job for "Envelopes".
Also, make sure the guides are set to fit the envelopes snugly.

You will need to use the manual feed slot which is above the paper tray.

The manual feed is meant for labels and envelopes
