Step 1: Clean the CVT Glass and the Printhead Lenses

Before you perform the Print Calibration Process, it is important to clean the CVT Glass and the Printhead Lenses.

To Clean the CVT Glass:

  1. Crumple up a piece of paper and, with moderate pressure, use the paper to remove any particles that might be stuck on the CVT glass. Then use a damp, lint-free cloth to clean the glass. Only use Xerox Cleaning Fluid or Xerox Anti-Static Cleaner to clean the glass. Do not use water. Pour the cleaner on the cloth. Do not pour it directly on the glass.
