Black lines on copy come from toner cartridge, or drum unit, or fuser unit which is in the back. check drum and see if you can see line, back of machine with flash light you may be able to see line on fuser roller. Be carefull Fuser is hot.
A copy that is good and then starts to get lines usually the drum unit...

Ink tends to overflow at the bottom guide rollers and the roller gets coverd in ink and causes the black line!The best will be to take it to a dealer and have it cleaned!Good Luck!

try to include cleaning all the roller, that's cause also for a print line under it.

Hi,

There are problem in your toner, in toner there is a drum which are scratched, you have to replace this drum.

Problem will be resolve.

Are the lines vertical or horizontal?

vertical lines can be caused by several things.
Since you said that cleaned the rollers, then here are other options
1: Most common is a bad toner cartridge.
2: try cleaning the fuser entrance guide.
3: could be a defective formatter - formatter replacement the fix.
4: worn fuser. fuser replacement is the fix.

horizontal lines are probably repetitive down the page, and are usually caused by a defective toner cartridge or fuser assembly. occasionaly a transfer roller will cause it as well.

Toner loves to get baked onto the fuser and cause all kinds of print problems. Not much you can do but to replace the fuser when this happens.

1. Charge – Print Quality (PQ) -- The charge roller evenly distributes a negative charge on the photoconductor (PC) drum. This evenly distributed charge acts as the film that is discharged (exposed) by the laser to create the latent image.
a. Print Quality effected: Faint, Entire Black background, Grey Fog/Haze
b. Parts Involved:
i. Drum -- A drum cartridge is coated with a photoconductive material that allows electricity to pass when exposed to light. As an example of why this can be the failure, if you leave a drum out in light long enough, you will get dark backgrounds or just black pages. However, drums do wear out over time too; specifically the photo material the drum is coated with. As this degrades, more of the positive electricity on the inside of the drum gets through and grabs toner, as if the laser wrote to every square inch of it. A damaged or defective PC drum can cause black streaks/lines, voids, speckles and various other print quality problems.
ii. Charge Roller – Also known as the BCR or Bias Charge Roll. The charge roller pulls double duty. It energizes the outside of the drum with negative energy and as a result it cleans any previous latent images. If the charge roller were failing to energize either due to the HVPS or the charge roller itself, it wouldn’t clean any previous unused toner deposits from the last revolution would start to accumulate and appear on paper more and more causing haze. A missing charge roller causes completely black pages.

iii. HVPS – High Voltage Power Supply -- Responsible for charging components such as the inside of the drum, the charge roller, and transfer roller. If the HVPS does not give enough to the charge roller it can fail in erasing the drum, causing entirely Black pages to be printed.

Most likely cause by the drum unit. Replace drum or upgrade printer.

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 paper.

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 the seals.

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
