HP Designjet 4000 Printer series - Manual (Page 173)

Caution Do not use commercial cleaners or abrasive cleaners. Do not
wet the platen directly because you will leave too much moisture behind.
Do not wet the rubber wheels at all (not even with the cloth).
6. Clean the cutter ramp with the damp cloth.
7. Clean the exposed part of the wheels with a dry cloth. Ideally you should clean
the whole circumference of these wheels.
How do I 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
Printheads > Replace printheads now. 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.
3. Open the window and apply a few drops of oil from the Maintenance Kit to the
pads on either side of the carriage.
