CHAPTER 3. MASTER RESET AND PROGRAM RESET

1. MASTER RESETTING

Master resetting clears the entire memory and resumes initial values.

Master resetting can be accomplished by using the following procedure:

The master reset can also be accomplished in the following case.

In case power failure occurs when the machine has no battery

attached to it, the master reset operation is automatically performed

after the power has been plugined the AC cord to the wall outlet.

(This is because if power failure occurs with no battery attached to

the machine, all the memories are lost and the machine does not

work properly after power recovery; this requires the master reset

operation.)

2. PROGRAM RESETTING (INITIALIZATION)

This resetting resumes the initial program without clearing memory.

This resetting can be operated at below sequence in PGM mode.

Note: In case power failure occurs when the machine has no battery

attached to it, the master reset operation is automatically per-

formed after the power has been restored.

The stepping motor is driven at a constant voltage by Sanken

STA471A.

Printing speed 50mm/s

< CPU’s PORT >

< Driving steps >

RECEIPT MOTOR

* When the motor is at rest, the same phase as the final excitation

phase is RUSH energize for 10 ms to turn off all phases. 3Turn all

RAS ~ RDS and JAS ~ JDS into L.

No energizing should be allowed at lease 30 ms after stopping the

motor before restarting.

When starting the motor, the first excitation phase is RUSH ener-

gized for 10 ms to start the motor.

3-2. HEAD CONTROL

HEAD:832 dots in all. Printable range: 384 dots at receipt side; 384 dots

at journal side

Related PORT

* When turning on or off the printer power supply, make sure to turn /

STB1, 2, 3, 4 to “H”.

* Do not turn on without paper.

* THERMAL HEAD power supply control : Turns ON when P81= “H”;

turns OFF when “L”. (The power supply for HEAD and STEPPING

MOTOR is shared). When printing is finished (when the motor is

stopped) Athe power should be turned OFF.

* Before printing or feeding paper, perform A/D conversion in ** ms

after the printer head is turned ON and make sure the voltage is sta-

ble.

(The power supply of the printer head should be turned ON and OFF

by using the regulator IC.)

5-3. KEYSCAN MATRIX

5-4. DISPLAY

This machine has an LCD display, 5 x 7 dots, 2 lines, at the front side

and a 7-digit LED at the pop-up side.

• Display DIGIT signal

The above ST0 ~ ST6 are display digit signals.

ST0: 1st digit ~ ST6: 7th digit

• Display SEGMENT signal

The LED segment signal is outputted by writing SEGMENT data in

the /CS3 space.

6. POWER SUPPLY

7. REWRITING FLASH MEMORY

IPL from EP-ROM: After IPL SW is set to ONA the program is started

from EP-ROM by turning on the power.

The program on EP-ROM is transferred to flash

ROM by switching the banks through S-RAM.

8. DRAWER

This machine has a 1 channel of drawer port. (+ 1 channel is reserved

for the CPU PORT) O R No open sensor is provided.

The driving time for the DRAWER solenoid are as follows: 50ms (max)

45ms (min)

9. PRINT RATE

384 dots/1 line

10. A/D CONVERSION

The printer power supply voltage should be measured at more than 10

ms after the printer is turned ON.

11. BUZZER

PIEZO type BUZZER

The oscillating frequency is 4.0kHz m0.5kHz

12. RESET

The RESET signal is generated when:

1) The mode key switch is turned from SRV to a position other than

SRV’(excluding OFF).

2) The power is turned ON more than 10 seconds after the power is

turned OFF. (The reset signal may not be issued if the POWER-

OFF time is short.)

CHAPTER 5. DIAGNOSTIC PROGRAM

1. TEST ITEMS

The test items are as follows:

* Starting DIAG.

DESCRIPTION OF EACH DIAG PROGRAM

1) DISPLAY BUZZER TEST

1Key operation

100 3

2Test procedure

The decimal point on the LED and the cursor on the LCD will shift

from the lower digit to the upper digit in steps of 1 digit (every 200

msec)

After that, all segments will turn on (about 1 sec)

These two modes are repeated.

At the same time, the buzzer sounds continuously.

3Check that:

A) Each position is correctly displayed.

B) The brightness of each number is uniform.

C) The buzzer sound is normal.

4End of testing

You can exit the test mode by pressing any key. The following is

printed.

2) KEY CODE

1Key operation

101 3

2Test procedure

3Check that:

KEY code : Every time a key is pressed, the hard code of that key

is displayed as a decimal number.

When a key is pressed twice or pressed in an incor-

rect manner, --- will be displayed.

4End of testing

You can exit the test mode by turning the mode switch to a position

other than the PGM mode. The printer prints as follows:

KEY check sum code

2Test procedure

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

If the sum check code is not entered, the check is made using the

sum check code of the default keyboard arrangement

The sum check data for each model is entered to the front 4 digits of

the DIAG code, and that data is compared with the key data added

until the final key (CA/AT) is pressed.

Both data are the same, the test ends, printing the number given

below.

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

3Check:

A) The content of completion print

4End of testing

Note: Calculation of key sum check data

Hard codes (hexadecimal number) at the position (excluding

feed key) where there is an input data contact are added.

However, the end key (TL) is not added.

This data to which hard codes have been added is converted into

a decimal number value, which will become the sum check data

that will be entered when DIAG is started.

5) MODE SWITCH TEST

1Key operation

2Test procedure

The above X must be read in the correct order. (If the contact is

open, 9 will be displayed.)

3Check:

The display during testing and the content of the completion print.

3Check the following.

X: 1 - Paper present at the receipt side

O - No paper at the receipt side

Y: 1 - Paper present at the journal side

O - No paper at the journal side

4End of testing

You can exit the test mode by pressing any key and the printer prints

the following.
