what you probably brushed over was the transfer roller(black and spongy?). first try running 20 or 30 blank copies through the machine. If that doesnt work take a dry paper towel and gently wipe and rotate that black roller. that should take care of the problem. If the roller needs replaced you should have a technician do it. You could break the machine beyond repair.

It's under the small fold down cover situated front right.
Just above and to the right of the canon logo.

Hello,
on analogue copiers, if You have dark copies, that means that You need to clean optics ( mirrors and lenses - maybe some toner get to them ) or check/clean/replace the fixing film!
Regarding poor copy, clean/vacume/change the transfer roller ( beneath the drum unit - on paper path from drawer/bypass, before fixing unit ).
Hope that helps!

yes that it 's the most possibillity.
but you must be assure that :
- the paper is not moist. (it makes pale copies)
- the glass has you cleaned up. (it makes black background uneven)
- the transfer unit is not dirty. (it makes black background)
