Checking for clogged nozzles
We recommend that you check the nozzles for clogs
each time you print to ensure quality results.
Ways to Check for Clogs
There are two ways to check for clogs.
❏
Print Nozzle Pattern
At specified intervals, the printer prints a test
pattern at the start of normal printing. When
printing is complete, you can visually inspect the
pattern to determine whether there may be faint or
missing colors in the preceding or following
printout.
