Duty Cycle Restrictions (Printing Solid Blocks)

There are restrictions on the duty cycle because of the heat generated by the receipt thermal print head when printing solid blocks (regardless of the length of the block in relation to the print line). The restrictions are ambient temperature, the percentage of time (measured against one minute) of continuous solid printing, and the amount of coverage.

Caution:  When the duty cycle approaches the limits shown in the table, the receipt print head heats up and shuts down. This may damage the print head.

To avoid this problem, do one or a combination of the following:

•Reduce the amount of coverage.

•Reduce the time of continuous solid printing.

•Reduce the ambient temperature.
