Black spots on printouts.

We have a Cannon MFC multi color laser printer, we changed the black print cartridge and when we print black/White , the printouts have black spots and other letters in the background. Can anyone please let us know if they had the same issye and what they did to fix it.

 

Thanks

Re: Black spots on printouts.

Thank you nvenktesh,

 

Your paper, toner cartridge or the need to clean an internal unit can factor into the issue.  Please first ensure that supported paper is being used: Paper drawer/16 to 32 lb (60 to 120 g/m2); Stack Bypass Tray/ 16 to 47 lb (60 to 176 g/m2).  Note:  Highly textured, very smooth or shiny paper do not print well.


If print or image quality is affected, and when replacing your Canon toner cartridge, cleaning the Fixing Assembly is very useful.  Visit the link and select the article "Cleaning the Machine" for details on cleaning the assembly.
