When you see your print is polluted with a clear ink stamp coming from the guide plate, you must clean the guide plate and replace the foams and roller assy.
Use Colorado M-series prescribed:
Microflex gloves for handling ink
Lint free cloths and swabs
Cleaning liquid (IPA)
For information on the prescribed maintenance materials, see List of Colorado M-series maintenance materials.
Wear the prescribed gloves when contact with ink or maintenance materials is possible. Gloves should always overlap sleeves. Follow the Safety Data Sheets (SDS) guidelines carefully in order to ensure maximum safety.
If necessary, dampen the cloth with the cleaning liquid to remove any remaining ink.
Use the prescribed cleaning liquid. Do not use any other cleaners.
