Service Station Removal and Cleaning
Summary: Procedure for removing/re-installing and cleaning the service station
Applicable Products: iJetColor Press
Tools/Parts Required: Small Philips screwdriver
Cleaning/Replacing Service Station Items
The Service Station contains separate areas/devices that are used to perform the following tasks.
 Cleaning. The Wiper Roller cleans the Printhead nozzles of excess ink and debris.
 Printing/Purging. The Printing Platen acts as a base to support media during printing. It also contains a purging area;
which captures and absorbs ink that is purged, to help keep nozzles clear.
 Capping. The Capping Station seals and protects the printhead nozzles when not in use.
 Evacuating Waste Ink. In addition to the function of supporting the above items; the Service Station Tray is lined
with wicking material that absorbs the waste ink and transfers it out of the Tray and into the “waste ink trough”.
This waste ink then flows from the “trough” to the “Waste Ink Tray”, which is located behind the Ink Tank Door.
As the above components become worn/dirty, from use, they can lose their ability to perform as intended.
If you experience print quality issues that are not resolved by performing the steps found in the Troubleshooting Section
under “Print Quality Issues”; it may be time to have the Service Station, or components within the Service Station,
cleaned or replaced.

seconds for the print engine to power off (all control panel light’s off). Then turn the Main Power Switch OFF.
WARNING
If the Printhead Cartridge is still installed; when you remove the Service Station, the
Printhead will remain un-capped. This can cause dehydration of nozzles and printing
issues. If you want to reduce the chance for printhead nozzle dehydration; it is highly
recommended that you eject the Printhead and follow the procedures described under
“Printhead Cartridge Storage and Handling”, before you begin this process.

Cleaning the Service Station
Caution: Please be sure that you are using proper cleaning techniques to clean items that come in contact with the
printhead. Use only distilled or deionized water and lint free cloths. If you don’t follow this rule, you will introduce
contamination into the printhead; which can damage the printhead and ink system.
Wiper Roller Removal and Cleaning or Replacement
Tip: Although the wiper roller can be cleaned; this process is time-consuming. When you factor in labor costs; you may
find it more cost-effective to replace the wiper roller instead. We also recommend that the wiper roller be replaced
whenever a new printhead is installed.
Removal:
1. Lift up, about one inch, on the Wiper Motor Assembly; to expose the latch
retaining screws [C] (one at each end).
NOTE: Early versions of this assembly did not have retaining screws.
2. Carefully loosen the two small screws retaining the wiper roller latches.
Tip: To avoid losing these screws; don’t remove the screws. You only need to back-
out the screws far enough so the latches can be opened.
3. Release the two latches that secure the wiper roller.
4. Remove the Wiper Roller from the Wiper Motor Assembly.

Station from the Tray; as described on the previous pages.
2. Wipe the Tray with a damp, lint-free cloth to remove the major ink buildup. Be careful not to damage/peel-off
the wicking material; from the surface of the Tray.
3. Then rinse the Tray using tap water.
4. Allow the tray to dry.
NOTE: If the Tray shows signs of wear or damage (wicking material torn or coming loose from surface of tray)
the Tray should be replaced. If the Service Station is more than one year old, depending on monthly volume, it
may be worthwhile to replace the entire Service Station instead of replacing components.
5. Reinstall the Service Station Printed Circuit Board, Wiper Motor Assembly, Printing Platen and Capping Station,
into the Tray; as described on the previous pages.
Suggestion for High Volume Users:
For printers that are being used at high volumes (over 200,000 pieces per month), we recommend purchasing a second
service station to reduce down-time for Service Station Maintenance. The new/clean service station can be swapped
with the dirty one. Then the dirty Service Station can be cleaned according to the above instructions and made ready for
the next time Service Station Maintenance is required.

You don’t need to open the Print
Engine. Shown for clarification purpose
10. GENTLY push in on the Service Station with one hand, while slowly turning the “Large Gear” clockwise with the
other hand. It should be easy to turn this gear and the service station should start to drive into the print engine
squarely.
Once the Service Station moves about ¼ inch past the “Bar” (shown in previous step), stop turning the gear. Do
NOT manually drive the Service Station into the print engine beyond this point.
NOTE: The “Large Gear” is located on the non-operator side of Print Engine; as shown below. You don’t need to
open the Print Engine to access this gear.
11. Turn the printer’s Main Power Switch ON; then press the control panel’s ON/OFF button.
After printer initialization (~45 seconds) the Print Engine will automatically pull the Service Station the rest of
the way in.
NOTICE: If the Service Station should get jammed during this process (you hear motor stall noise or gear slipping
noise); immediately turn OFF the printer’s Main Power Switch. This is one of the only exceptions for turning off
the printer using the main power switch, before properly powering-down the print engine. Remove the Service
station by turning the Large Gear counter-clockwise. Re-check that the Wiper Roller is properly installed and
latched at each end. Then re-install the Service Station starting from step 8 above.
Tip: The “Eject Service Station” button, located in the M Series Toolbox, should be used if the service station
needs to be removed in the future.

12. Verify that the wick, located on the bottom of the Service Station, is hanging into the
waste ink trough; as shown (as viewed looking into the Service Station Slot, from the
exit end of the printer).
13. Close the Ink Tank Door.
NOTE: If using an older printer you will need to re-install the Exit Roller Cover
plate, using the 4 screws, before closing the Ink Tank Door.
Make sure the cover is installed in the proper orientation.
TIP: Since the Exit Roller Cover is also an integral part of the frame structure;
you may need to push in on the outer frames to get the screw holes in the
Exit Roller Cover to align.
14. Close the Top Cover
15. Power the printer on and Test for proper operation.
Still Experiencing Print Quality Issues?
If you still experience print quality issues, after performing all the cleaning processes, outlined in this section, please
refer to the “Troubleshooting Guide” for additional help. If you have exhausted all cleaning and troubleshooting options,
and you have replaced the Printhead Cartridge and Wiper Roller; then this may indicate that the printer requires
technical service.
WARNING
Waste-ink from the Service Station flows through
wicking material and out the hole, located on the bottom
of the service station. If this wicking material is not
directed into the trough; waste-ink will build up on the
base of the Service Station Slot. This misdirected waste-
ink will eventually find its way onto the Ink Tanks, inside
the body of the printer and even under the printer;
causing damage to the system.
