Clean screan the glass is dirty how can i clean it

The cover plate is above the glass white surface of the scanner. If this is the same dirty stains will come out on copies.
The glass must be clean.
By feeding the original documents through the ADF, the scanner lamp is no longer the path to scan, the ADF is responsible for passing the original document over the scanner, while it remains still placed on the side under a thin glass is to a large glass side. This also must be clean, otherwise you will be black lines on each point or spot on the glass.
Good luck ...

Hi,
Did you try to clean beneath the copy glass?
On digital machines, when the copy glass or optics are dirty, copy becomes verry light.

How many copies do you have? pres 123 button.
It also could be that you need to change the toner station, by the book it goes 300000 copies.
But I bet on dirty copy glass and dirty scanner assy.Clean the glass with glass cleaner and polish it with dry cloth.

Hi,
Soft cotton cloth would be fine to clean front screen of TV. Do not use any liquid or detergent in cleaning.
Thanks.

The cause of this problem is usually a dirty scanning glass (there might be ink or white out on the glass). Check the glass really closely or the cause could be dirty optics or a bad CCD board. There are mirrors underneath the scanning glass. Dirty optics can cause lines when faxing or copying. If you can not access these mirrors, they would have to cleaned by a technician.

depends on type of unit,but most separate by opening oven door and removing the screws around the perimeter of the door, be careful reinstalling as to get inner and outer glass re-positioned right along with insulation,this is especially critical because the outer glass can't withstand self-clean temps and will break

Found the solution at http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=SupportDetailTabAct&fcategoryid=239&modelid=13170&kbpage=yes , then enter "clean platen glass" in the search window, and select item #1 "ERROR LCD: PLATEN GLASS DIRTY, CLEAN PLATEN GLASS ". This gives step-by-step instructions on how to clean the area dealing with the platen glass.

suggest you bring your printer to the nearest authorised repair center and have them do the cleaning...it will save you cost
