Examine the Nozzle Check Pattern on a PIXMA MG3620

Learn how to understand the nozzle check pattern on a PIXMA MG3620 to see if a print head cleaning is needed.

To see if you need to clean the print head on your PIXMA machine, you must first print a nozzle check pattern.

Once the sheet prints, examine the pattern to determine if the print head should be cleaned.

Examine the nozzle check pattern

The nozzle check sheet will print, and will look something like this:

1. Review the pattern in A:
   • Are there any missing lines? (In the sample below, D looks good, but E has missing lines.)

     

   • If there are missing lines, clean the print head.

2. Review the horizontal rows in B:

• Are there any white streaks in the pattern? (In the sample below, F looks good, but G has white streaks.)

  

• If there are horizontal streaks, clean the print head.

 In the first image, (C) represents the total number of sheets printed so far on the printout of the nozzle check pattern (shown in increments of 50).
