6. Use a clean, absorbent lint-free cloth, slightly dampened with isopropyl alcohol, to wipe off loosened
ink deposits from the platen.
NOTE: Isopropyl alcohol is not provided in the Maintenance Kit.
CAUTION: Do not use commercial cleaners or abrasive cleaners. Do not wet the platen directly
because you will leave too much moisture behind.
7. Clean the cutter ramp with the damp cloth.
8. Clean the exposed part of the wheels with a dry cloth. Ideally you should clean the whole
circumference of these wheels.
Lubricate the printhead carriage
The printhead carriage occasionally (about once a year) needs lubrication to slide easily along the slider
rod.
1. To gain access to the carriage, go to the front panel and select the icon, then Printhead
management > Replace printheads. The carriage will slide into the middle section of the printer.
CAUTION: If the carriage is left in the central part of the printer for more than seven minutes. it
will try to move back to its normal position in the right-hand end.
2. Take the bottle of oil from the Maintenance Kit that is supplied with your printer. A replacement kit
can be ordered if necessary.
