Ink Jet Print Head

This section describes how to replace the ink jet print head
and the ink cartridge (see the sequences of figures on pages
VI - VII), how to clean the print head and preserve optimum
print quality.
It also describes how to obtain the print test (page XI).
Your printer comes with a monochrome print head with a
replaceable ink cartridge. A colour print head with
replaceable ink cartridge is available as an option (see
specific paragraph in this section).
ALWAYS use manufacturer-original Ink Jet Print Heads.

Replacing the Print Head

See the instructions embossed on the inside of the front
cover.
When the printer is not powered, idle or in standby mode, the
print head carriage is locked in its rest position (at the
extreme left).
Do NOT try to move the print head carriage manually.
The carriage lock is released by an internal motor prior to
any printer operation.

Print head removal

The print head is removed to replace the ink cartridge
when an "end of ink" condition is signalled, to repeat
insertion in the case of faulty printing or to exchange it
with a colour print head.
•
With the printer powered, press CARTRIDGE to position
the print head carriage in the head loading position.
•
Open the front cover.
•
Pull the black lip on the front of the print head housing
slightly towards you (see the traced arrow in the figure on
page VI); the print head will be released.
•
Holding it by its casing, remove the print head from the
printer.
Monochrome print head with replaceable ink
cartridge
The monochrome print head supplied with your printer has a
replaceable ink cartridge. This cartridge can be substituted
several times before you have to change the entire print
head.
To substitute the empty ink cartridge (see the sequence of
figures on page VII):
•
Remove the print head from the printer, as described in
the previous paragraph.
•
Holding the print head vertically, with the nozzles facing
downwards, remove the ink cartridge from the print head,
pulling it upwards.
