Maintaining the Product
Document Glass and Constant Velocity Transport Glass
To ensure optimum image quality at all times, clean the
document glass and constant velocity transport glass monthly,
or more often if needed. This helps avoid output with streaks,
smears and other marks that transfer from the glass area when
scanning documents.
Control Panel, Keyboard, LCD Display
Regular cleaning keeps the Control Panel, Keyboard and LCD
Display free from dust and dirt. To remove finger prints and
smudges, clean the control panel, keyboard and LCD screen
with a soft, lint-free cloth, lightly dampened with water.

Use a cloth moistened with water to clean the Document
Feeder, Output Tray, Paper Trays and the outside areas of the
WorkCentre Pro 421.
To clean the glass areas, use
a lint-free cloth, lightly
dampened with water or
Xerox Lens and Mirror
