Canon imageclass MF 6550

There is dirt on the ADF glass. Normally to the left of the flat bed glass, there is a thin glass strip. Clean it with a damp cloth.

Does this problem appears when you use the page feeder? Yes, then you have to clean the platen glass using a cloth dampened with water. See upside of your printer for more information.

Hi,
you have problem with laser shuter on laser unit. It needs to be fixed or replaced.
This is canons factory fault, and if the machine is under waranty call service.

Hope that helped!

Did you clean beneath copy glass ( adf copy glass and platen )?Did you clean scaner also?
Clean the laser unit.
Not genuine toner isnt best solution.

Try to print something.If the print is OK, then the problem is in copy glass and scaner.

I mean can you scan a text document with the "photo" option and see if you are still encountering problem. And check this out, he tells how to reset to factory and test scanner. http://www.fixya.com/support/t342579-just_started_printing_blank_pages

Does it do it on prints aswell as copies?

If so open up the Left hand side door if you peer inside at the fuser (hot bit) can you see any damage. if so needs replacement.

Also could be the drum, look in the same area at the green/blue cylinder, these do up to approx 30,000 pages.

Hope this helps.

We have a photocopy canon MF 6530 and on the screen appeared information Platen glass dirty , clean platen glass.
I have clean glass there we put paper for copy , but it seems that is not this problem, Photocopy stoped copy or print it use just paper.
Could you please let me know what do I need to clean.

Yours sincerely

If your copies are clean when you scan them by opening the top and laying the original on the platen, you need to check the scanner for the ADF (automatic document feeder). It's a narrow strip of glass to the left of the scanning platen glass. Clean it with a soft cloth dampened with clear water. (Look for some type of deposit that aligns with where you see the line on the page.)

Clean the heads, the printer is not reading cartidges. Is yours a model that needs the ink levels reset to funtion correctly, then do this too.

Clean the platen glass and make sure the isn't any debris or ink on it, especially by the roller. If you make a copy thru the ADF while the ink is still wet it will deposit on the glass.
