what model machine what color

control panel - printers- highlight printer but dont select - top right printer preferences - maintance- clean printer heads etc clean with all options available. should fix the problem.

You may be able to spray a clear coat over the print. There may be a slight color change.
Try a few types to test.

If by smearing you mean the print is also rubbing off? Then you definately have a fuser unit issue. The fusing unit is the assembly that heats up and "fuses" the toner onto the page. When these start to go bad, usually on one edge or the other the print will smear/double image/wipe off of the effected area. One test you can do to verify a fuser problem is to print a page and then when the page is about half way thru the prcess, shut the printer off. Open the top and remove the toner cartridge, pull out the page and see if the lower part is not smeared. Basically what your checking is to see if the print is ok BEFORE it goes thru the fuser. Based on your description I would suspect your fuser is going bad.
Good Luck and Thank You for using Fixya.

I think you need to change the tranfer belt assm.
If all the colors are smearing .

Or all of your toners are bad and leaking,
Hope this helps

Okay, this was the problem I posted a few days ago. It's fixed now, so in case you have the same problem with smearing, here's what the help desk from Canon suggested: Open the cover and remove the ink cartridges. There is a gray lever in front of the cartridges. Lift this lever and the printhead can be easily removed.
Our printhead had a buildup of black ink on the surface. I carefully removed this with rubbing alcohol. I let the printhead dry and replaced everything. No more smearing. Imagine a help-desk that actually helped!

uninstall the driver of your machine .reinstall again use the cd driver to update

Our Dell AIO A940 stopped printing black ink (it went throught the motions but he paper came out blank). Finally got it to print by selecting:

PRINT, PROPERTIES, PAPER SETUP, SPECIALTY PAPER, PHOTO/GLOSSY

Maybe it will work for you! Good luck!
