PH window cleaning

• The PH window, if contaminated, blocks the path of the laser beam and the surface of the
photo conductor can no longer be exposed properly. This could result in image problems,
including white bands or white lines on the print image.
• The PH window is provided with a cleaning mechanism that prevents any image problem
caused by a dirty PH window from occurring.
A. PH window cleaning procedures
• Slowly pull to the front the PH window cleaning tool provided for the PH window of each
color and push it back into the original position. This allows the cleaning material
mounted on the PH window cleaning tool to remove any foreign matter from the surface
of the PH window.
• The machine is not equipped with any mechanism that automatically cleans the PH win-
dow. This makes it necessary to clean the PH window manually at regular intervals.
B. PH window cleaning timing
• Clean the PH window of each color when the drum unit/K is replaced with a new one.
