Daily Maintenance, Ink Cartridge
Prior to shift startup, the cartridge orifice array should be cleaned of any
debris or ink build up.
Requirements:
•
Deionized or distilled water (DO NOT USE TAP WATER) for
POROUS INK
ONLY
•
Sponge Swabs (p/n: 5760-832)
Procedure:
1. For
POROUS INK ONLY
cartridges, lightly dampen sponge swab
with deionized water.
2. For
NON-POROUS INK ONLY
cartridges, hold sponge swab
against orifice array of cartridge. Press and hold the purge button
on the rear of the print head for at least ten seconds. This will fire all channels of the ink
cartridge and dampen the swab with ink. The ink will act as its own solvent for cleaning.
3. Rub up and down across the orifice face with light force several times with one side of
the sponge swab.
4. Turn the swab over and make one final light rub stroke top to bottom.
5. Immediately press and hold the PURGE button on the rear of the print head for 5-10
seconds to reprime the orifices. Because ink will eject during the channel purging, a
piece of paper, cloth, or comparable material can be held in front of the orifice array.
Do NOT hold the ink catch material against the orifice array as print quality will be
degraded.
6. If print quality becomes unsatisfactory during any shift repeat this procedure.
Wipe pen
cartridge face up
and down
several times.
Immediately
press and hold
the purge button
for 5-10 seconds.
