Print head care and precautions
•
Always keep the print heads and ink
cartridges sealed until they are to be used.
•
Remove the ink cartridge from the print head
ONLY to replace it. Do NOT remove and then
reinsert it.
•
Remember to remove the protective tape
before inserting the print head/ink cartridge in
the printer. Take care not to get ink on your
clothes; the ink in the head/cartridge stains.
•
Do NOT attempt to refill the print head/ink
cartridge with ink, as this damages the print
head and the printer.
•
DO NOT shake the print head; it is not a
fountain pen. If it does not print, do the
cleaning operations described in “
Cleaning
the print head ”.
•
If you think that the number of pages printed
with the current print head/ink cartridge is
fewer than usual, try cleaning it. If the “end of
ink” condition persists, the print head/ink
cartridge is empty and requires replacing.
Always make sure that the print head is in its rest
position BEFORE switching off your computer.
Switching off your printer before your computer
will guarantee this. When the printer is powered,
the print head carriage will automatically return
to its rest position and go into standby mode
after approximately two minutes of inactivity.
q Cleaning the print head (Clean)
The print heads are cleaned automatically at
regular intervals while the printer is powered.
This operation clears the print head nozzles,
guaranteeing the ink flow. If you have a problem
with the printing quality that is not solved by this
automatic nozzle clearing operation, you can do
the same operation, using the “CLEAN” function
in the Printer Care tab in Printer Monitor (see the
specific paragraph in “
Preparing the printer using
the printer monitor ”).
If you have a problem with the printing quality that
is not solved by the nozzle clearing operation
described above, try cleaning the print head, as
follows:
1. Open the printer cover.
2. Position, release and remove the print head
that is causing the problem.
3. Clean the electrical contacts (gold part) 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.
4. Re-insert the print head in the printer and
close the cover.
If there is still no improvement in the print quality,
try cleaning the print head nozzles.
