Density of Receipt Print Lines
When the 7193 prints high density print lines (text or graphics), it automatically slows
down to a rate slower than 1020 lines per minute. High density print lines are defined as
lines with over 57% of the dots printing on the line (there are 448 total dot columns on the
print station).
Duty Cycle Restrictions (Printing Solid Blocks)
There are restrictions on the duty cycle because of the heat generated by the receipt
thermal printhead 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 approches the limits shown in the table, the receipt
printhead will heat up and shut down. This may damage the printhead.
To avoid this problem, do one or a combination of the following:
1.
Reduce the amount of coverage.
2.
Reduce the time of continuous solid printing.
3.
Reduce the ambient temperature.
