I found a solution on your website giving a list of replacement parts to solve the problem. Unfortunately, I did not write down the site or the list of parts. In the end, I located a printer repair website that uses local technicians to repair the copier. I am waiting for a reply from them giving me a list of references in my area. So, the copier is not fixed - yet. I may be contacting you for your help so I've saved your email to me.
Thanks. You did help me in the past to fix my car cd changer. The dealership wanted to replace the unit for $600.

Line thru the documents when using top feeder

you didn't state model #, but raise your feeder up and look for the "skinny" piece of glass on left side of your large glass and make sure you clean it well.

Cannon MF6580 fax machine says check document. i have tried everything, any suggestions?

Open the top cover of the document feeder and look inside where the paper goes into machine. There is a flag that comes loose and the machine thinks there is paper in the feeder. You have to remove the top cover carefully(just a tab on each side of the cover). After removing the cover there should be another cover on that cover remove a couple of screws and take it off. Put the flag back into its holder and put everything back together....Carefully!!!

Scanning a legal size document

Move the document feeder front guide towards the rear of input tray, line up with 8 1/2" marking. This should inform the machine to register for 8 1/2 x 11 or 8 1/2 x 14 originals>fed lengthwise.

I have a WorkCenter M20 and I am unable to use the document loader on the top of the machine... why is this? I try to load the documents and press start, but then onlty a blank sheet is spit out, because...

What you want to do is this. Turn the machine off, then go to the back of the machine and unplug the document feeder, There is a white connector with 2 thumb screws holding it in place. loosen the 2 thumb screws and unplug the plug. With the feeder unplugged turn the machine back on and let it come to ready. Once it comes to ready turn the machine back off, then plug the document feeder back on and turn the machine back on. That should re detect the document feeder and work fine. The M20 for some reason just forgets it has a feeder and you have to force the plug and play portion of the software to detect the machine not having a feeder then seeing that is has one. I don't know why, not even the newest versions of firmware for the machine resolves that issue. Odd,,,,,
