Maintenance and Troubleshooting

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 available from Printek, or you
may use cotton swabs moistened with isopropyl alcohol. Please refer to Figure 12 for the following
instructions.
