8.1.2 How to clean an ink cartridge
Damage to the ink cartridge
Wrong cleaning leads to damaged ink cartridges and bad print
quality. Please stick to the described cleaning instructions of this User
Manual.
Please do not use chemical solvents or any cleaning agents. Furthermore do not use paper
towels, toilet paper, sponges, dry cloths or any other textiles with small abrasive fibers for
the cleaning of the cartridge nozzles.
Recommended cleaning utilities
• Use only fiber-free tissues for cleaning the ink cartridge nozzles
(see chapter 9.1 Consumables, on page 164). Please follow the
instructions below.
• Use only pure distilled water to damp the cleaning cloth. The water
can etch dried ink residues and may reactivate clogged nozzles.
Cleaning the
nozzle plate
• Dampen the cleaning cloth with a small amount of distilled water.
• Cautiously press the cartridge nozzles onto the tissue and wait
until the cloth soaks up a small amount of ink.
• Slowly wipe the cartridge nozzles on the tissue surface, in the
direction of the nozzle rows (see Figure 64).
• Optional: Insert the cleaned ink cartridge into the printer and use
the CLEAN HEADS function (Quick + Arrow down ) to purge
the nozzles.
Cleaning the
contacts
• Dampen the cleaning cloth with a small amount of alcohol.
• Do NOT bring the alcohol in contact with the nozzle plate (see
Figure 65)!
• Carefully wipe the contacts with the cloth.
• Check if all contacts are free of ink stains. If not, continue wiping
the contacts until all are shiny and stain free.
• Optional: To check if all contacts are completely clean, use the
following menu: SERVICE > HARDWARE TEST > Cartridge. If this
test shows MISSING DOTS: no for each cartridge, the contacts are
completely clean.
