Preventive Maintenance

This chapter describes procedures for printer preventive mainte-
nance. Following these recommendations can help prevent prob-
lems and maintain optimum performance.

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

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 of the machine.
