Chapter 1. Technical Overview
Safety
Personnel hazard areas have restricted access with appropriate warning labels.
Catastrophic equipment failures are inhibited with protective functions in major
areas of overload potential.
Preventive Maintenance
The T61215 is designed to eliminate the requirement of scheduled maintenance
procedures, such as alignment, adjustment, or lubrication. Preventive mainte-
nance is limited to periodic cleaning.
Dust and paper fibers should be removed
periodically with a soft cloth and brush or a vacuum cleaner. Clean the printer
case with a damp cloth and soapy water.
DO NOT use any abrasive cleaners or
solvents, as they will damage the case.

The printer must be allowed to reach room temperature before operating. Three
hours out of the shipping container is usually enough time for stabilization. Com-
plies with NSTA Program 1 & 2.
Heat Load Contribution
The average heat load contribution to the environment is approximately 1075
BTUs per hour (315 Watts) with a maximum potential of 3000 BTUs per hour (880
Watts) under continuous full-load printing conditions.
