Routine Service and
Diagnostics
Overview
This chapter discusses general cleaning, running diagnostic tests, and
understanding fault messages.
The printer requires no routine maintenance beyond regular cleaning.
Periodically remove excess paper chaff and dust from the ribbon and paper
paths. If print quality or paper motion deteriorates seriously even after
cleaning, contact your IBM service representative for prompt attention.
Cleaning Requirements
Periodic cleaning ensures efficient operation and clear print quality. If the
printer is located in a dusty area or is used for heavy duty printing, clean it
more often.
Cleaning The Outside Of The Cabinet
Clean the outside of the cabinet with a soft, lint–free cloth and mild detergent
soap. (Dishwashing liquid works well.) Do not use abrasive powders or
chemical solvents. Clean the windows with plain water or mild window
cleaner.
ATTENTION
Always apply the cleaning solution to the cloth; never pour cleaning
solution directly onto the printer.
<2> Switch off printer power and unplug the printer power cord
before cleaning the printer.
