C.1 About TCC
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.
