Avoiding printer problems

Preventing print head overheating

Overheating of the thermal print head is one of the most common causes of printer problems. To avoid

overheating, do one or more of the following:

1. Reduce the amount of solid coverage when printing receipts.

2. Reduce the time of continuous printing, or the "duty cycle." The duty cycle is the percentage of time that

the printer can be actively printing in any sixty-second period of time. The duty cycle will vary for your

printer depending on the temperature of the room where you have set it up and the amount of print

coverage, and it is expressed as a percentage in the table below. For example, if the duty cycle is 50

percent, it means that the printer should only print for 30 seconds out of every minute. If the duty cycle

is 25 percent, the printer should print for 15 seconds and then be idle for another 45 seconds.

3. Reduce the temperature of the room where you put the printer. Keep in mind that the temperature may

also be aected if the printer is exposed to direct sunlight, or near a space heater, heat lamp, or other

heat source.

IMPORTANT: If the duty cycle exceeds the limits shown in the table below, the receipt print head will heat up

and shut down. This may damage the print head.
