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
Individual maintenance part expected life
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.
The motor drive FRUs contain the proper lubricant in the FRU. Use only the lubricant included.
Lubrication for replacement motors
When you install a motor drive assembly, you must grease the posts and gears to ensure proper performance
from the printer.
