6. Preventive maintenance

This chapter describes procedures for printer preventive maintenance. Follow these recommendations to help
prevent problems and maintain optimum performance.

Safety inspection guide

The purpose of this inspection guide is to aid you in identifying unsafe conditions.
If any unsafe conditions exist, find out how serious the hazard could be and if you can continue before you
correct the hazard.
Check the following items:
•
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

Lubrication specifications

Lubricate only when parts are replaced or as needed, not on a scheduled basis. Use of lubricants other than
those specified can cause premature failure. Some unauthorized lubricants may chemically attack
polycarbonate parts. Use IBM no. 10 oil, P/N 1280443 (Approved equivalents: Mobil DTE27, Shell Tellus 100,
Fuchs Renolin MR30), IBM no. 23 grease (Approved equivalent Shell Darina 1), and grease, P/N 99A0394 to
lubricate appropriate areas.
