4. PRINTER CONTROLThe PR-58HM printer is incorporated.

4-1. STEPPING MOTOR CONTROLThe stepping motor is driven at a constant current by SMA7036M (madeby Sanken).

1step: 0.125mm, 1dot: 1step

Printing speed: 50mm/s

<DRIVING STEP>

RECEIPT MOTOR

*When the motor is stopped, rush conduction must be performed for10ms 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 thefirst excitation phase to start the motor by acceleration control.

*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 printerhead power, A/D conversion must be performed to check that thevoltage is stabilized before starting the operation.

5. A/D CONVERSIONIn the ER-A520/530, the following three kinds of signals are input tothe A/D conversion port.

<CPU PORT>

5-1. PRINTER HEAD TEMPERATURE MONITORA voltage divided by the temperature detection thermistor of the printerhead and the resistor is input to AN0 pin.

The printer head conduction must be controlled as shown below.

5-2. PRINTER HEAD VOLTAGE MONITORThe voltage is supplied by the printer head power source, passed throughthe printer, and divided by the resistor is inputted to AN1 pin.

The A/D conversion value must be read after turning VHCOM signal(CPU P106) to "H" and stabilizing the voltage (after 10msec).

The printable voltage range of the printer is 15V~26V. The voltage iscalculated from the AN1 value and the A/D conversion value of the ref-erence voltage.

5-3. REFERENCE VOLTAGEThe reference voltage (2.495Vm0.085V) generated by KIA431F is suppliedto AN2 pin.

469 (DEC) t VREF t 557 (DEC)

VREF 469 (DEC) corresponds to VREF = 2.41V at VCC = 5.25V

VREF 557 (DEC) corresponds to VREF = 2.58V at VCC = 4.75V

2 Test procedure

The keyboard is checked using the sum check code of the keycode.

If the sum check code is not entered, the check is made using thesum check code of the default keyboard arrangement

The sum check data for each model is entered to the front 4 digitsof the DIAG code, and that data is compared with the key dataadded until the final key (CA/AT) is pressed.

Both data are the same, the test ends, printing the number givenbelow.

If both data are different, the printer prints the error message.

3 Check:

A) The content of completion print
