Replacing the Ink Cartridge

See the sequence of figures on page VI (1f to 4f) for the
monochrome print head and on page VII (1g to 5g) for
the color print head and also the indications on the
template on the inside of the cover.
When replacing the ink cartridge, take care not to touch
the print head carriage shaft nor the area under the print
head carriage.
Any document inserted for printing will be expelled if
you remove the color ink cartridge.
When the ink cartridge in either of the print heads runs out
of ink, an "end of ink" condition is signaled: printing stops,
both ON LINE and POWER light indicators on the printer
operator panel start flashing alternately and an error
message is displayed on your PC screen.
To substitute the empty ink cartridge:
1. Open the printer cover.
The print head carriage will move automatically to the
head loading/replacement position of the empty print
head.
If you do nothing within the next 40 seconds, the print
head carriage returns to its rest position. To return to
the loading/replacement position, press ON LINE.
2. Release ONLY the ink cartridge from the print head
casing, pulling gently outwards the lateral lip on the print
head casing; do not release or remove the print head
casing from its chamber in the printer.
3. Remove the cartridge from the print head casing, pulling
it upwards.

4. Open the sealed ink cartridge container and remove the
instructions leaflet (which should be kept for future
reference).
5. Remove the ink cartridge from the container, holding it
by the thumb and finger grip.
6. Remove the protective tape/capsule from the new ink
cartridge.
Do NOT touch the ink pad area on the cartridge.
7. Insert the new cartridge in the print head casing
immediately, pressing in until it clicks into place.
8. BEFORE CLOSING THE COVER , press and hold
PAPER and press POWER for at least two seconds to
reset the ink counter.
The POWER light indicator will flash three times to
confirm that the counter is reset and a sheet of paper will
be inserted automatically and a nozzles test printed.
9. Close the printer cover.
If your printing operation was interrupted, it will now
resume automatically from the point at which it stopped.
If you have not inserted the new ink cartridge correctly,
the light indicators on the operator panel will continue to
flash. You must repeat the entire replacement operation.
If the quality of printing is not optimum, try cleaning the
print head (see Print Head Care in this section).
After replacing the ink cartridge several times, you must
replace the entire print head (complete with outer casing).
