Item Function
Top Spittoon This seals the reservoir and completes the main body of the
service station.
Wiper Shuttle This mobile part is propelled by the motor that contains the Wiper
and Cap. Depending on the position, spitting, wiping, capping, or
priming can take place:
Spitting: The printhead “spits” a little ink into the spittoon to get
the nozzles conditioned and ready for the next swath of printing.
Wiping: A physical action to pass the rubber wipers through the
printhead nozzles.
Capping: Parking the printhead to maintain nozzle heath during
printer inactivity, with a surrounding seal.
Priming: Squirts ink through the nozzles to clean and unblock
them.
Notes and considerations
The service station is oered as a complete service part for full replacement. The failures from this
subsystem are usually related to the mobile parts: motor or encoder failures that prevent the shuttle from
reaching the positions for capping or uncapping.
With the life primer system, tube pinching can present an issue (although it is designed to function for the life
of the printer).
When the Service Station is replaced, it is mandatory to reset the Preventive Maintenance Kit for the Service
Station, this will trigger a simple calibration that is done with the Service Station on the next printer startup.
The calibration measures the length of the Service Station (shuttle front bump to shuttle rear bump), which
ensures a correct capping position.
Electronics
All the controlled movements for the Service Station are done from the Printer Bundle Board located on the
right-hand side of the printer. Issues with the Service Station can also be related to this control board.
Ink system overview
The ink system consists on the Ink Supply Station to pump ink from the supplies and the Ink Tubes to carry ink
to the printhead.
