MAINTENANCE
Dryer Cleaning
To clean ink and debris from the dryer, use a lint-free cloth dampened with water.
Clean all external surfaces with the exception of the underside of the dryer.
Reseat Connectors on Main PWA and Carriage Boards
Integrated circuits may become weakened or damaged by electri-
cal discharge. Do not touch or work near integrated circuits with-
out wearing an ESD wrist strap.
Ribbon connectors can be easily damaged if incorrectly handled.
Observe extreme caution when handling the ribbon connectors to
avoid damage.
Many problems can be corrected simply by removing and reseating connections
found in circuit assemblies. This process helps to clean the contacts and can
dissipate any static electrical charges that might have developed.
