The maintenance module (MM) is a sled that contains stations for wiper, cap/spittoon,
and print zone platen.
To position the correct station into place, a stepper motor moves the sled horizontally,
and a
DC motor moves the sled vertically. The maintenance module:
Cleans the printhead of excess ink and debris.
Keeps the printhead protected and hydrated while not in use.
Provides a safe place to spit ink that is used to keep the nozzles clear.
Provides a suitable base for supporting the media during printing. This is done with the
print zone platen station.

The maintenance module should be replaced as part of annual maintenance or after
printing one million inches.
NOTE:
The maintenance module is not intended to be end-user serviceable, although it is
a service part for technicians.
