APPENDIX A. MISCELLANEOUS NOTES
1) Print duty
•
When printing exceeds the allowable print duty cycle, the printer automatically detects the print
head temperature rise. If the print head temperature continues to rise, the printer stops the print
head until the temperature goes down to the threshold level.
•
When printing is stopped due to high print head temperature, the ERROR LED blinks as shown in
Table 3.5.1.
•
When the head temperature error occurs, the printer goes offline. The printer automatically goes
back online when the print head temperature falls.
2) Data transmission
Data should be transmitted after the printer power is turned on and initialize operation completes.
3) Manual cutter (only for the manual cutter installed model)
The roll paper should be cut off after finishing paper feed.
4) For faster receipt printing
This printer supports two kinds of the paper feeding speed (See Section 1.5.1, Paper feed).
If the ESC d
n
or the GS V
m n
is used effectively, the printer can print the receipt faster.
5) Other
Because plated steel plate is used in this unit, the cut edges may get rusty.
