Cleaning the Print Head
If you encounter printing quality problems, run the self print tests which are
described in Chapter 2. This test will demonstrate whether the print head
nozzles are operating properly or not. If you find that there are problems,
perform the following steps. The following section applies to both monochrome
and color print heads.
To clean the print head:
• Remove the print head from the printer.
• Clean the electrical contacts on the print head and on the print head carriage
with the brush supplied with the storage box.
CAUTION: If there are traces of ink on the electrical contacts, you MUST
NOT use the brush, otherwise you may permanently damage them. Instead
use an absorbant material, such as blotting paper, to remove the ink traces
from the contacts.
• Insert the print head in the printer and run the print test again.
If you are still unable to make the print head operate correctly, do the
following:
• Dampen a paper tissue and then squeeze it to remove excess water.
• Remove the print head from the printer.
• Holding the print head with the printing nozzles facing downwards, blot it
against the paper tissue, pressing lightly. Repeat this on different areas of
the paper tissue until the ink nozzles are clean.
• Insert the print head in the printer and run the print test again.
If the print head still does not operate correctly, you must change, or if it is
monochrome, prime the print head (see the specific sections in this chapter).
