General Cleaning

The printer requires periodic cleaning to ensure efficient operation and clear print quality. Clean the printer approximately every three months or after 250 hours of operation. If the printer is located in a particularly dusty area, or is used for heavy duty printing, a shorter cleaning interval is recommended.

The following cleaning procedures are applicable for pedestal and floor cabinet model printers.

WARNING

Disconnect the power source before cleaning the printer.

WARNUNG

Vor dem Säubern des Druckers ist die Netzverbindung zu unterbrechen.

Exterior Cleaning

Clean the cabinet exterior with a soft, lint–free cloth and mild detergent. (Dishwashing liquid works well.) Do not use abrasive powders or strong cleaning agents. Clean the clear windows with plain water or mild window cleaner. Always apply the cleaning solution to the cloth; never pour the cleaner directly onto the printer. Vacuum the ventilation slots at the rear of the printer cabinet.

Interior Cleaning

Paper chaff and ink accumulation inside the printer is normal during printer operation. However, ex- cessive paper chaff and ink accumulation can degrade printer performance and print quality. Most pa- per chaff accumulates around the ends of the platen and ribbon path.
