The black print head has a few blocked nozzles.
Inkjet printers need to be used frequently to prevent ink drying out and blocking the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages, then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer than replace the print head.

Is it a white or black line?There can be a piece of paper in the drum cartridge or the drum is damaged!Scratched!Try replacing the drum cartridge!Good Luck!

f print quality does not improve by the standard cleaning of the Print Head, clean the Print Head deeply. Cleaning the Print Head deeply consumes more ink than the standard cleaning of the Print Head, so clean the Print Head deeply only when necessary.

2. Clean the Print Head deeply. (1) Press the (Maintenance) button repeatedly until y appears.
(2) Press the Black or Color button.
The machine starts cleaning the Print Head deeply. Do not perform any other operations until the machine completes the deep cleaning of the Print Head. This takes about 2 minutes.

When the deep cleaning is completed, the LED returns to the copy standby mode. To check the print head condition, print the nozzle check pattern.

See " Printing the Nozzle Check Pattern".

If the problem is not resolved, turn off the power and clean the Print Head deeply again after 24 hours.
If the problem is still not resolved, replace the FINE Cartridge with a new one.

See " Replacing FINE Cartridges".
If the problem is still not resolved after replacing the FINE Cartridge, contact the service center.

Printing the Nozzle Check Pattern
Print the nozzle check pattern to determine whether the ink ejects properly from the print head nozzles.

NOTE If the remaining ink level is low, the nozzle check pattern will not be printed correctly. Replace the FINE Cartridge whose ink is low.
See " Replacing FINE Cartridges".

try to change the color ink. horizontal banding (the pink or other color lines appearing means horizontal banding) when there is a problem on one of the heating element of the printer head. since almost all canon printers have head built in the inks, replacing the faulty ink will solve the problem. if not then the controller of printhead on the carriage and mainboard needs to be checked.

You don't need to do head alignment, because it is for vertical banding in printout. Vertical banding can be minimized by disabling high speed option without doing head alignment. If your printout have horizontal white lines, do check nozzle and head cleaning, or you can minimize white lines by printing in best quality (photo).

Check for scratches on the drum surface. If you have ran a lot of copies on there, its a good time to get it serviced. It could be the cleaning blade on the drum as well.

I was getting a verticle black line and I had to clean the glass, the long white bar above the glass, and the white and black rollers before my problem was solved.

White lines through copies White lines can appear on a copy in either a horizontal or vertical direction. How the white line appears on the copy will determine the cause and solution. Horizontal lines Horizontal white lines usually indicate the ink cartridge is running out of ink or has some clogged ink nozzles. Try the following steps: 1. Some of the ink cartridge ink nozzles may be clogged with dry ink. Use the ink cartridge cleaning service to try to clear them. Follow the steps below: 1. Verify that there is plain white paper in the Input tray. 2. Press Setup. 3. Press or to select Tools and then press OK. 4. Press or to select Clean Print Cartridge and then press OK. The unit prints a test page. 5. Examine the test page. If the print quality of the page is good, stop here. If the print quality appears to be getting better, run the Clean Print Cartridge utility again 2. If the self test appears better, Increase the copy quality setting (Normal or Best) and try copying again. If the quality is still poor, continue to the next step. 3.

If the ink levels are not low, clean the cartridge face and electrical contacts at the back of the print carriage. 1. Open the front of the unit to access the ink cartridges. 2. After the ink cartridges are at the center, unplug the power cord from the back of the unit, and remove the ink cartridges. The power cord must be removed to ensure that the unit is not damaged during the cleaning process. 3. Clean the cross-hatched area of the ink cartridge with a soft clean cloth that is slightly dampened with clean water to remove any build up. Avoid cleaning the ink cartridge nozzle plate. Cleaning this area can force foreign matter into the ink nozzles and plug them. Figure 2: Cleaning the ink cartridge 1 - Clean in the cross-hatched area only 2 - Do not touch the nozzle plate 3 - Clean the copper-colored contacts 4. With a soft lint free cloth slightly dampened with clean water, clean the copper-colored contacts on the back of the ink cartridges. 5. Allow the cartridges to dry before reinserting them. 6. Close the unit, and plug the power cord back in. 7. Print a self-test page to check the results. Follow the steps below to print a self-test page. 1. Press Setup. 2.
