Platen Open Detection
The platen open status is automatically detected before printing or paper feed takes place. If the
platen is open (platen open), the printing or paper feed operation is blocked.
Note:
If an attempt is due to print immediately after reset or opening/closing the platen, paper feed takes
place for several tens of dots before printing starts. This is performed to offset the backlash (gap)
between the printer motor gears produced by opening/closing the platen.
No Paper Detection
If there is no more paper being fed in during printing or paper feed, a “no paper” (paper end) is
detected and the printer automatically stops. Also, printing does not take place if paper has not
been loaded at the start of printing.
Supply Voltage (VDETP) Detection
During a printing operation, constant monitoring takes place to determine if there is a sufficient
supply of voltage (VDETP) for printing. If VDETP is detected (i.e. the voltage goes below
VDETP), the printer driver continues printing after restricting the voltage drop (due to printing) to
a minimum by reducing the number of simultaneously colored (printed in black) dots during
printing. However, if VDETP occurs when the number of simultaneously colored dots is at a
minimum, an error (Voltage error: VDETP) is output and the printing operation stops.
Note:
If a voltage error is output, resume the printing after replacing the battery pack.
