Cleaning the Printer

The printer has a 25-pin connector option with the following pinout
designations and signal mnemonics:
Periodic cleaning helps maintain the appearance and reliability of the
printer. When cleaning the printer, inspect both the outside and the
inside for signs of damage or wear.
Glass cleaners containing ammonia will cause permanent
damage to the printer cover.
Do not use abrasives or solvents (acetone, ketone, toluene, or
xylene) to clean any part of the printer or permanent damage to
the printer will occur.
Note: Micro Clean II (P/N 901-438-xxx) is the only cleaner
recommended for the printer case. Other cleaners can damage the
printer case. Contact Intermec Inside Sales at 1-800-255-6292 to
