Item Function
Absorber Base This is made of foam and is located under the service station
on top of the printer structure. It works as an additional diaper
in case ink spills out 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 offered 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 remote-controlled board located
on the right-hand side of the printer. Issues with the Service Station can also be related to this control
board.
Paper path and Cutter
Functionality
The paper path
This comprises all the elements of the printer in contact with the paper, designed to hold, move, and
manage it in a controlled manner in order to print.
Paper can be loaded using a roll, which is mounted on the rear spindle, or single sheets loaded from
the Multi-Sheet Tray, or single sheets loaded singly.
The paper passes from its source (Roll, Single Tray, or Multi-Sheet Tray) until it touches the Out-Of-Paper
Sensor, when the printer detects the presence of the paper and proceeds to load it.
