Print Head - NEC SuperScript 100C User Manual

Position the print head carriage in the head loading position, open the top
cover, release and remove the print head (see the specific sections in this
chapter).
Clean the electrical contacts on the print head and in the housing on the print
head carriage with a slightly damp lint-free cloth, taking care not to touch
the print head nozzles.
Re-insert the print head in the printer, close the top cover and press any key
to return the printer ON-LINE.
If there is still no improvement in the print quality, try cleaning the print head
nozzles.
This operation MUST NOT be repeated systematically, as it will damage the print
head. It should ONLY be attempted as a last resort, before changing the ENTIRE

print head.

Dampen a tissue handkerchief with distilled water; squeeze it slightly to
remove any excess water.
Remove the print head from the printer (see the specific section in this
chapter).
Holding the print head with the nozzles facing downwards, blot it against the
handkerchief, pressing lightly.
Repeat the blotting operation a few times on different areas of the
handkerchief, to clean the nozzles.
Reinsert the print head in the printer and print the "demo" page to check the
quality of printing (see the specific section in this chapter).
