If you’ve experienced horizontal banding or a color shift in your inkjet prints, it’s likely there’s a clogged printhead nozzle. Here’s a step by step video that shows the quickest way to perform a nozzle check on a Canon large format inkjet printer to determine if you have a clogged nozzle. The nozzle check is the first step in the troubleshooting process for banding and color shift.

The nozzle check will print a grid. Any breaks in the pattern usually indicate a clogged nozzle. If you find that there is one, the next step is to perform a head cleaning (video to come soon). Then, check your results after a head cleaning with another nozzle check just to be sure it worked.
