4. PRINTER CONTROL
The PR-58HM printer is employed.
4-1. STEPPING MOTOR CONTROL
The stepping motor is driven at a constant current by SMA7036M (made
by Sanken).
1step: 0.125mm, 1dot: 1step
Printing speed: 50mm/s
<CPU PORT>
<DRIVING STEP>
RECEIPT MOTOR
*
When the motor is stopped, rush conduction must be performed for
10ms in the same phase as the last excitation phase to turn off con-
duction to all the phases.
3
RAS~RDS and JAS~JDS are turned to "L".
Allow at least 30ms before boosting after stopping.
When boosting, rush conduction must be performed for 10ms in the
first excitation phase to start the motor by acceleration control.
4-2. HEAD CONTROL
HEAD: All864dot
Printable area:RECEIPT side, 360dot;
JOURNAL side, 360dot
Related PORT
*
When turning off the printer power supply, make sure to turn
/STB1,2,3,4 to “H.”
*
Do not turn on the printer under paper empty state.
*
During printing or paper feeding, after 10ms of turning on the printer
head power, A/D conversion must be performed to check that the
voltage is stabilized before starting the operation.
4-3. OTHER PORTS
PHUPS: "1" Head up
PRES : "0" Receipt paper end
PJES : "0" Journal paper end
VHCOM: "1" Thermal head power control: On at "H" and OFF at "L".
Turn off the power conduction when printing is completed (the
motor is stopped).
