SCP 5 Subsystem Maintenance
Subsystem Maintenance contains information regarding the component life of the machine.
Procedure
WARNING
Switch off the electricity to the machine. Disconnect the power cord from the customer
supply while performing tasks that do not need electricity. Electricity can cause death or
injury. Moving parts can cause injury.
1. Clean the Pick Rollers on every call.
2. Use the Control Panel to check maintenance item counters.
3. Compare the counter values to those listed in Consumables.
4. Advise the customer of any routine maintenance items that are approaching or over the
service limit.
Inspection
Rollers
Replace the Rollers when you see any of the following defects:
• Flat spots
• Out of roundness
• Cracked rubber
• Loss of traction (tackiness) causing pick or feed failures
Gears
Replace Gears that show any signs of wear or damage. Look for these problems:
• Thinned gear teeth
• Bent or missing gear teeth; check especially where a metal gear drives a plastic gear.
• Fractured or cracked Gears (oil or incorrect grease on a plastic Gear can cause the Gear
to crack).
Belts
There are rubber belts in the printer. Inspect the belts for wear. Look for these problems:
• Loose rubber particles below the belts indicate a worn belt.
• Missing teeth in the belts.
• Cracking or moderate fraying; a small amount of fraying is inevitable, so look for other
signs of wear before replacing the belt.
Lubrication
The printer is lubricated during assembly at the factory and does not require periodic lubrica-
tion. Some parts require lubrication following replacement. These parts are identified in the
replacement procedures. When lubricating during replacement, use the grease approved for
all Phaser printers.
CAUTION
Plastic parts will deteriorate when unspecified grease and chemicals are used. To avoid dam-
age to the printer, use only Rheolube 768 grease.
