C.4 TCC Procedure
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.
A slight increase in MTTR results in a large increase in MTTF. The customer
and you win in the end.
Use the historical information from the maintenance log to analyze the
reliability of the printer and of a component within the printer. 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.
Damaged, worn, or broken printer components cause intermittent problems
and accelerate the aging of mechanical components. Pinched or frayed wires
can randomly short circuit. Paper dust, dirt, and toner on rollers, bearings,
and gears cause premature failures. Replace any rollers that have flat spots,
surface glazing or cracking, or dust and toner contamination.
C.4.1 Cleaning and Inspection
Clean and vacuum toner, paper dust, and dirt from the following areas of the
DEClaser 1100 printer:
Caution:
Always use the special vacuum cleaner in Section D.2 for cleaning
up toner. The toner powder can pass through the bag or filter of a conventional
vacuum cleaner and cause damage.
• Inside and outside of the cassette and optional feeder
• Feed roller assembly
• Remove and clean the EP-L cartridge
• Paper path guides
• Fixing unit entrance and exit areas
• Facedown delivery rollers
