The Color Laserwriter 12/600 PS and Color LaserWriter 12/660 PS printers uses a silicone based oil that can easily be cleaned up from the exterior plastic case using a lint free cloth and a mild non-abrasive household cleaner/degreaser such as Fantastik or 409. Spray a small amount of the cleaner onto the cloth and wipe the plastic case. Do not allow any cleaning solution to enter into the printer.
Oil that has spilled onto the photoconductor, transfer drum, or paper feed rollers can be cleaned by printing on lint free paper until all of the oil is absorbed. Usually anywhere from 5 to 50 sheets of paper will remove the oil. Do not use ammonia- or alcohol-based cleaners on or near the Color LaserWriter 12/600 PS or Color LaserWriter 12/660 PS printers.
To prevent damage to the photoconductor, do not touch or use any cleaning materials on the delicate gray roller that is the photoconducting surface.
The photoconductor may be damaged from scratches or contamination due to oil or fingerprints. Image quality defects in the printed output may result with areas of light print, scratches or banding that repeat vertically down the page every 5.07" (129mm). The defects are typically visible in areas that have toner applied to them.
