Cleaning
In normal environments, the printer should be cleaned after printing a few rolls of paper or if there are voids in
the printout. For optimum performance and life, you should clean the Print Head and Platen Roller whenever
you load new paper.
To clean the printer areas as described below, use a Thermal Head Cleaning Pen and MCR Cleaning Card
available from Psion Teklogix, or you may use cotton swabs moistened with isopropyl alcohol. Please refer to
Figure 16 for the following instructions.

• Turn the printer off. Open the Paper Door and remove the paper.
• Using a Thermal Head Cleaning Pen, clean the surface indicated on the Print Head.
Caution: Do not use sharp objects to clean the print head. This may damage the printer and require
service. Such damage is not covered under warranty.
• Clean the Black Mark Sensor below the print head.
• Clean the Tear Bar
• Clean the Platen Roller. Turn the platen roller with your finger to clean the entire surface.
• If a Magnetic Card Reader is installed, pass an MCR Cleaning Card through the MCR slot to clean the

You may also experience a build up of paper dust in the printer. This may be removed using a can of
compressed air or by vacuuming.
To clean the exterior of the printer, turn the printer off and use a soft cloth moistened with a mild detergent.
