10.4.2 Cleaning ink cartridges by hand
Caution! Inexpert cleaning can damage the ink cartridges and render them
useless. Heed the following hints to avoid damage to the print system:
• In case of print quality issues, always run the cleaning functions of the
franking machine accessible from the M
ENU first. Read chapter 10.4.1 on
page 88.
• You should manually clean the ink cartridges in exceptional cases only
where intensive cleaning fails to restore the normal print quality.
• For cleaning, make sure to use a soft, lint free cloth moistened with
demineralized water. Small fibers could clog the nozzles. Too hard or dry
cloths could scratch the nozzle plate. Such scratches make the ink
cartridge useless because they prevent the ink-jet from being correctly
positioned during printing.
• Never use any chemical cleansers either.
Move the ink cartridges into the change
position.
• Open the M
ENU.
• Choose P
RINT SYSTEM.
• Choose C
HANGE CARTRIDGES in the
submenu.
Removing the cartridges
• Remove one cartridge as usual
(see page 83).
Cleaning
• Moisten a lint free cloth with demineralized
water.
You can also use distilled water or normal tap
water if demineralized water is not at hand.
The minerals contained in tap water could,
however, leave residues in the print head.
