Print Head
Voltage
Error
1) If the voltage is not 24 V
±
15%, a head voltage error is assumed
and the printer is automatically set to offline mode. For the
SERIAL INTERFACE: If Xon/Xoff flow control is selected then
Xoff is transmitted. If DTR/DSR flow control is selected, the
DTR signal goes to “mark” (BUSY) state.
2) When the power voltage is set to the above normal value, the
printer becomes usable.
3) When the head voltage error detection is disabled by the FS 9
+n
command, the head voltage error detection function is not
executed.
Cutter
Error
1) If a cut operation does not terminate within approx. 4 seconds, a
cutter error is assumed as a hardware error. The printer is
automatically set to offline mode. . For the SERIAL
INTERFACE: If Xon/Xoff flow control is selected then Xoff is
transmitted. If DTR/DSR flow control is selected the DTR signal
goes to “mark” (BUSY) state.
2) When the power is turned on again or the hardware is reset, the
printer becomes usable.
3) If the cutter blade is not located at the home position when the
printer is initialized, the cutter is automatically positioned.
4) This detection function is valid only when the cutter use mode is
selected with the DIP switch.
5) If a paper cutting command is received when the cutter is being
disconnected, a hardware error is assumed after approx. 4
seconds.
Motor
Power
Saving
Function
1) After the motor operation stops, an electric current is made to
flow for one phase only to maintain the pulse motor phase for
approx. 10 seconds.
2) When the electric current is off at the start of motor operation,
an electric current is made to flow at the same phase for up to
dozens of milliseconds to fix the pulse motor phase. Then the
motor operation starts.
MCU
Operation
Error
Detection
Function
1) The watchdog timer detects MPU operation errors to prevent the
printer from being damaged by an abnormal operation.
