Black line down the page
Is the line on the front of the page or on the back? If on the back,
you need to clean the platten which is the piece of plastic under the
If its on the front, and you say "It lools like a rubber cover
may be missing off of one of the rollers", could you upload a picture
of this roller? I don't recall any covers on rollers in Canon printers.
Try this, print out a blank page. If line is still there, print
out 10 blank pages. If line is still there and has not faded, this is
unusual and may need servicing. There may be a problem with the encoder
strip (it's a clear plastic strip with black lines running the length
of the printer slightly behind the head), Try cleaning it on both sides
with a little windex on a q-tip. It's delicate so be careful.
If the line looks faded after printing 10 blank pages, some ink has
dripped onto something that is contacting the paper. This could be a
roller, the bottom of the head carriage or even a hair or piece if dust
that is stuck in the machine or on the bottom of the head. In this
case, I would recommend cleaning everything. Revove the head (tell the
machine you're going to replace ink, and when it moves the head into
the centre position unplug the power cord.
Remove the head and clean off any dust or hairs on the bottom. Run a
Q-Tip along the bottom of the carriage assembly wherever you can. Clean
any accessable rollers. If you can get at it, clean the wiper on the
purge unit (the unit the head sits over when it is parked), as well as
Reinstall the head and ink, close the lid, power up and retry printing.
I hope this helps. If not, there could actually be a fault with the printhead or one of the circuit boards
