Paper Path Grit Roller Inspection
The three paper path grit rollers must be inspected every month.
1. Inspect the print rollers for ink residue and debris. If none is found, proceed to the
next PM task. If residue is seen, perform the following steps to remove it.
2. Lightly moisten a toothbrush with a small amount of DI water.
3. Gently scrub the grit rollers to remove any ink or paper dust. Manually rotate the
rollers to ensure that they are completely clean.
4. Use a shop towel to dab the rollers and remove any excess moisture. Do not rub
the towel back-and-forth or fibers will be left on the grit rollers.
