Item Function Bottom Spittoon This part acts as an ink reservoir when spitting and nozzle health operations are performed. It contains diapers that prevent the ink becoming liquid. Top Spittoon This seals the reservoir and completes the main body of the service station. 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.
