All pages print with a gray shadow - Brother MFC-7440N Laser Printer

Are you using a reconditioned cartridge?

If so use a real Canon cartridge

If the paper really is being burnt then there is a fault with the fuser roller temperature control. This would also make a smell. If this gray sheen is made of toner then this may be the laser unit not putting out enough power. The optics could be dirty. One thing to try before attempting repair- Reduce the print density to minimum in the printer advanced settings. This increases the Laser power. Good luck

Repetitive ghosting defects like this are caused by either a bad drum in the cartridge or a damaged or worn fuser assembly. Try a different cartridge first, but make sure you print at least 50 pages to make sure that any toner residue is cleaned of the fuser in the printing process. If the defect is still there then you will need to either repair or replace the fuser.

This solution is unconventional but it worked for me. The black roller on my MFC had irregularities on it and was creating horrible printouts. I pulled out the drum and cartridge and cleaned the large black roller. I used furniture polish to make the roller very smooth. Now it prints really nice.

This is called backgrounding. It is a common issue with this machine when you print past the reccomended out or use inferior remanufactured carts. This is usually either a poorly adjusted doctor blade in the cartridge, or if it is an HP cart, it has a prematurely full waste bin and is transferring waste toner to the page. Either way, replace the cartridge.

your cartridge is defective.. just replaced a new one.

Hi fa1103:
Gray background
1. Do not use media that has already been run through the printer.
2. Try using a different type of media.
3. Print a few more pages to see if the problem corrects itself.
4. Turn over the stack of media in the tray. Also, try rotating the stack 180°.
5. Open the Configure Device menu at the printer control panel. On the Print Quality
submenu, increase the TONER DENSITY setting. See the user guide.
6. Make sure that the environmental specifications for the printer are being met.
try these steps to see if they work for you.

hello

this sounds like a bad black ink cart, or the fuser rolls built into the printer are dirty.

you can swap out a black cart to test that theory, you can also just print a single blank page (no text or graphics) onto a piece of glossy paper and see if there is anything there after its gone thru the printer.

if the piece of paper has stuff on it it had to come from the rollers inside the printer.

service required,unless your comfortable changing out parts in your printer.

norm

maybe the scan unit need to clean first you most sure that the toner cartridge is original and new then start clean th scan unit reflector

i would redownload latest drivers 1st ok then dop a nozzel clean up then maby cheak status of black use only oginal ink parts not generic
