Cleaning The Print Head; Transporting The Printer - Olivetti JP 90 User Manual

•
The rest of the print test contains a print-out of the printer
SETUP (currently selected operating parameters), the
currently selected Character set and the FONT TEST with
the resident portrait or landscape fonts, depending on the
value of the "Orientation" parameter. The contents of this
part of the print test will vary according to the emulation
selected.
In most cases, the operating parameters will be determined
by your printer driver, and will override the internal printer
set-up. If you wish to modify your printer set-up, see the
section Using Software .

Cleaning the print head

The print head is "primed" periodically while the printer is
powered. This operation clears the print head nozzles,
guaranteeing the ink flow.
If there is a problem with the printing quality that is not solved
by the automatic nozzle clearing operation, remove the print
head from the printer and clean it, as follows:
•
Press CARTRIDGE to position the print head carriage in
the head loading position.
•
Open the front cover, release and remove the print head
(see the specific paragraphs in this section).
•
Clean the electrical contacts on the print head and on the
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 front cover
and press CARTRIDGE to return the print head carriage to
its rest position.
User Guide - Ink Jet Print Head
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 print head.
•
Dampen a tissue handkerchief with distilled water; wring it
slightly to remove any excess water.
•
Remove the print head from the printer.
•
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 run a print test to
check the quality of printing (see the specific paragraph in
this section).

Transporting the printer

Always make sure that the print head is in its rest position
before moving or transporting the printer. To ensure this,
always switch off the printer BEFORE switching off the PC
(or other host) to which it is connected.
