Inspection guide
The purpose of this inspection guide is to aid you in identifying the intervals, based on page count, at which
parts must be inspected (for visible physical damage), cleaned, or replaced.
If any unsafe conditions exist, find out how serious the hazard could be and if you can continue before you
correct the hazard.
As you service the machine, check for the following:
• Damaged, missing, or altered parts, especially in the area of the On/O switch and the power supply
• Damaged, missing, or altered covers, especially in the area of the top cover and the power supply cover
• Possible safety exposure from any non-Lexmark attachments
Use the following table to determine when specified parts should be inspected:
