APPENDIX A: MISCELLANEOUS NOTES
1) Print duty
• When printing exceeds the allowable print duty cycle, the printer automatically detects the
print head temperature rise, stops logic-seeking, and enters full-column print head
movement operation. This stops the temperature rise by lowering print duty. If the print
head temperature continues to rise, the printer stops the print head. In this case, the user
should be aware that the printing speed may slow significantly.
• 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.
• The upper limiting conditions on continuous printing are as follows. (An example test pattern
is shown in Figure A-1 and Figure A-2.)
[Conditions] • Maximum continuous printing time: 1 hour
• Ambient temperature: 25°C {77°F}
• Number of line feeds:
Set the number of lines to be fed based on the following ratio:
A: ratio between printed lines and fed lines
• Print head duty:
The number of print columns must be 20 or less in full-column print head
movement operation.
• Print color selection:
Do not switch the print color frequently. When a black-red-black or
red-black-red color selection sequence is regarded as 1 switching, the user
should perform switching according to the rate shown below.
B: Print color switching rate
2) Data transmission
Data should be transmitted after the printer power is turned on and initialize operation
completes.
3) Manual cutter
The roll paper should be cut off after finishing paper feed. After cutting the roll paper, the
paper should always be fed 6/144 inches before any subsequent print (to cancel the gear
backlash).
4) Reverse paper feed
Normally, the printer can feed paper 1 line (including the gear backlash) in the reverse
direction, when ESC K or ESC e is executed. However, do not reverse feed more than 48/144
inch (including the gear backlash).
