• When the power supply voltage drops to the lower limit, the printer stops printing once and
then starts printing rest data on that line again more slowly than before.
• When the head temperature rises to the upper limit, the printer stops printing once. If the
head temperature falls down to the normal level, it begins to print again more slowly than
before.

1.2.2 Switches
1.2.2.1 Usual Operation
In the normal mode, pressing panel switches executes the following functions;
(1)
Operate
This switch turns the printer on and off. It is the secondary switch in the power supply circuit.
CAUTION
Unplug the power cable from the AC Inlet when connecting/
disconnecting the Interface cable to/from the printer.
(2) Pause
This switch alternates printer activity between printing and non-printing states.
If this button is held down for over 3 seconds when the printer is in the non-printing status, the
Micro Adjust function and Font selection are enabled. If it is pressed again, these function are
disabled.
(3) Load/Eject
- Loads the paper when the printer is out of paper.
- Ejects the paper to the paper park.
(4) LF/FF
- Feeds a line if pressed shortly.
- Feeds the continuos paper or eject the cut sheet.
(5) Tear Off
Advances the continuos paper to the Tear-OFF position. If it is pressed again, the paper is
moved to the TOF position.
(6) Bin
Selects the CSF bin number when the CSF is used.
(7) Font
Selects the font from the list on the panel when the Micro Adjust function is enabled.
(8) Micro Adjust
The Micro Adjust switch is available in the Micro Adjust mode.
Micro switch executes micro feed forward or backward by 1/216 inch one by one.
The TOF adjustment is enabled in the TOF position after loading the paper, and the Tear-off
adjustment is enable in the Tear-off position.
