Checking and Cleaning the Print Head
If your printed image shows a color shift or horizontal lines, you should
check the print head to see if any nozzles are clogged or deflected. If one or
more nozzles is clogged, you can run a cleaning cycle to clear the nozzles.
Checking the Print Head
Check the print head by printing a nozzle check pattern, as described below,
and then examine it to determine whether the print head needs cleaning.
1. Make sure roll paper or letter- or A4-size cut sheet paper is loaded in the
printer. If you need to check the white ink nozzles, use film to ensure
that the ink is visible.
2. Press r Menu .
3. Press d until TEST PRINT is selected, then press r .
4. Make sure NOZZLE CHECK is selected, then press r.
5. Select PRINT WITH WHITE INK or PRINT NOW , then press r.
• Select PRINT WITH WHITE INK if you think there may be a
problem with the white ink nozzles. This option ensures that white
ink is included as part of the test pattern. If necessary, the printer
will replace cleaning liquid with white ink in the print head before
printing the pattern.
• Select PRINT NOW if you know the white ink nozzles are working
properly and you don’t need to check them. The printer may
include white ink as part of the test pattern, but only if it’s already
loaded in the print head.
6. Press OK to start printing the nozzle check pattern.
Note: The printer
automatically checks the
print head and cleans it if
necessary, but you can
adjust the settings (see
page 86).
Note: You can have a
nozzle check pattern
automatically printed on a
regular basis. See
page 86.
Note: The printer
normally replaces white
ink with cleaning liquid
when it’s shutting down.
