C.1 About TCC

The Total Call Concept (TCC) procedure is performed in concert with the Start

FIP which is found in Section 4.1. When you perform the TCC procedure

you enhance the reliability of the printer and reduce the number of service

calls that are required to support the printer. Return to the Start FIP for

troubleshooting information.

The Start FIP is a tool that you use to isolate a malfunction and ﬁnd the

speciﬁc FIP to turn to for further testing and repair.

C.2 Cleaning and Inspection

Damaged, worn, or broken printer components cause intermittent problems

and accelerate the aging of mechanical components. Vacuum the toner, paper

dust, and dirt from all rollers, bearings, and gears. Inspect, clean, or replace

all rollers. Look for ﬂat spots, surface glazing, splitting, or dust and toner

impregnation. Look for loose or missing screws; cracked, broken or bent paper

path guides; nicked or frayed wires; and missing E-rings and disconnected

springs.

If you are uncertain that a component is worn, broken, or contaminated but

suspect that it is, replace it anyway. This preventive action will reduce the

number of service calls over the lifetime of the printer.

Caution: Always use the special vacuum cleaner shown in Table D–2 for

cleaning up toner. The toner powder can pass through the bag or ﬁlter of a

conventional vacuum cleaner and cause damage.

Thoroughly inspect and clean the following parts of the printer:

• Inside and outside of both cassettes

• All paper path guides

• Fixing unit entrance and exit areas

• Exit rollers

• Exit stacking tray

• Remove and clean the case of the print drum cartridge. Inspect but do not

clean the surface of the print drum.

• Remove and clean case of the developer cartridge

• Walls and ﬂoor of the empty print drum and developer cavity

• Inspect and clean the inside of the printer and look for toner spills, paper

dust, or foreign objects.
