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/Off 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
• Printer and input options are sitting flat (for example, not sitting on cables or hanging over a ledge)
• Printer is properly set on any input options
Use the following tables to determine when specified parts should be inspected:
