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.
Example of the nozzle check patterns with gloss black ink
Normal Clogging
When the printed patterns show the nozzle clogging state, run a head cleaning.
Printing Nozzle Check Patterns
Clogged nozzles cause blurred or streaky printing or printing in unintended colors. If you are experiencing print
quality problems, print a nozzle check pattern to see if the nozzles are clogged.
c
Important
When printing a nozzle check pattern, load a sheet of paper at least 21.5 mm (0.85") wide and 38.6 mm
(1.52") long.

Note
Printing the nozzle check pattern with black mark detection enabled may increase the amount of

Paper width is 108.0 mm (4.25"), paper length is 174.8 mm (6.88"), and gap between labels is 3.0 mm (0.12")
Note
When printing nozzle check patterns on die-cut labels, the amount of remaining paper required
depends on the paper width, paper length, and gap between labels. Since some combinations require
a maximum paper length of 531 mm (20.9 inches), it is recommended to use continuous paper,
full-page labels, or the included roll paper.
