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

Hi Jason,

We have a canon color imageclass MF8450 c multifunction machine. Thanks

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.

Please contact us if further assistance is needed.

This is an 11 year old thread, our website has changed since then. Additionally, the imageCLASS MF8450c is an older model which we have retired. While that means that Canon USA no longer offers direct support for it, your friends here in the Canon Community are welcome to offer suggestions!

You can also speak with a Canon Upgrade Program specialist to help you score a modern replacement that would meet your current needs at a discount. You can reach them weekdays and Saturdays at 1-866-443-8002.

Hope this helps!
