Cleaning the Print Head
If the nozzles are clogged, faint colors, banding, or unintended colors appear on printouts. When such print quality
problems occur, print nozzle check patterns and check for nozzle clogging. When the printed patterns show the
nozzle clogging state, run a head cleaning.

Printing Nozzle Check Patterns
If the nozzles are clogged, faint colors, banding, or unintended colors appear on printouts. When such print quality
problems occur, print nozzle check patterns and check for nozzle clogging.
Note
The nozzle check pattern is printed to fit the paper width set on the printer's operation panel.
However, if the printer detects that the actual paper width is narrower than the set paper width, the
nozzle check pattern is printed to fit the actual paper width.
Media Forms that Can be Used for Nozzle Check Pattern Printing
❏ Continuous paper
❏ Full-page label
❏ Die-cut label with a length of approximately 112 mm {4.41 in.} or more*
❏ Tag*
2
*1: If the die-cut label is less than approximately 112 mm {4.41 in.} long, some portions of the nozzle check pattern
will be printed onto the backing paper.
*2: Since the pattern cannot be printed avoiding the holes in the tag, part of the pattern may be printed on the
platen through the holes.
