How to Identify and Fix Common Problems ?

Check the nozzle check pattern you printed. (1) If lines of this pattern are missing, the print head nozzles need cleaning. (2) If these patterns have white streaks, the print head nozzles need cleaning.
Streaks and unwanted lines could mean that the printer heads are out of alignment. There`s an alignment tool in the printer`s control panel. If that`s not the issue then the printer is dirty. Printer ink stripes may appear along the edges of the paper, which means there`s ink on the rollers and other parts.
Laser Toner or Drum Cartridge

The drum either forms part of the toner cartridge or installs as a separate consumable. In either case, scratches on its photosensitive surface can cause stripes or lines in output. Most cartridges include a spring-loaded shutter that opens when you insert the consumable into the printer.

If your printouts are blurry or smeared, try these solutions: Make sure your paper is not damp, curled, old, or loaded incorrectly in your product. Use a support sheet with special paper, or load special paper one sheet at a time. Make sure your paper meets the specifications for your product.
If you notice white or dark lines in your prints (also called banding), try these solutions before you reprint: Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if necessary. Make sure the paper type setting matches the type of paper you loaded.
What Is Banding? Banding is a defect in inkjet printing that will appear as horizontal or vertical lines, streaks or bands in the printed output. Everyone will eventually experience some type of banding with their inkjet printer.
A possible cause may be that appropriate paper is not used or the amount remaining in toner cartridges is running low.
One of the most common reasons behind color printing issues in the Canon printer is an empty cartridge. You should first check whether your cartridge still has ink. First, open the printer`s front door and remove the cartridge slowly and carefully. Look out for its ink levels.
There are four primary causes for horizontal banding on prints from inkjet printers, (1) nozzle clogs, (2) mis-aligned print heads, (3) low quality print settings (4) incorrect paper thickness settings. Below we will describe each of these causes for horizontal banding as well as ways to try and fix them.
Ever wonder why your prints sometimes appear faded or streaky? It`s usually because the printhead inside your printer is clogged or dried out. Like with most printers, Canon printheads can clog due to ink or dust drying up and collecting in the nozzle.
Go to the printer panel, click on Maintenance, then Paper Feed Adjust, then Adjust Print Quality, then select AUTO . Run another print after the pattern prints and scans. If the banding does not disappear you may have to go back through these steps and instead of AUTO, run the Manual Adjustment.
Vertical lines in prints are an early warning sign of a low ink cartridge, which may show up before the printer`s low ink alerts start. You can fix the problem by replacing the low cartridge. Gently shaking the drained cartridge a bit may help to get another few prints out of it without vertical lines.
