CHAPTER 3. MASTER RESET AND PROGRAM RESET
Service Manual
[1] MASTER RESETTING
Master resetting clears the entire memory and resumes default values.
Master resetting can be accomplished by using the following procedure:
Procedure A: 1) Unplug the AC cord from the wall outlet.
2) Set the mode switch to the PGM position.
3) While holding down both the JOURNAL FEED key
and [CL] key, plugin the AC cord to the wall outlet.
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 restored.
(This is because if power failure occurs with no battery attached to the
machine, all the memory will be 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.
Procedure: 1) Unplug the AC cord from the wall outlet.
2) Set the mode switch to the PGM position.
3) While holding down both JOURNAL FEED key
and RECEIPT FEED key, plugin the AC cord to
the wall outlet.
NOTE: 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 restored.

* 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
stable.
(The power supply of the printer head should be turned ON and
OFF by using the regulator IC.)

1) KEY/DISPLAY SCAN cycle: 10ms
2) Blanking time: 50us
3) KEY DATA READ timing: More than 10 ms from the fall of the

4. DISPLAY
The XE-A40S has an LCD display, 5 x 7 dots, 2 lines, at the front side
and a 7-digit LED at the pop-up side.
FRONT:
POP UP:
• 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.
Correspondence of DATA ~ SEGMENT
D0 ~ D6 → A ~ g
D7 → DP
[9] PRINT RATE

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 ± 0.5kHz
[12] USB I/F
The XE-A40S is equipped with 1 USB port (slave) as a standard provision. By use of the USB general-purpose ASSP device M66291
(RENESAS), it sends and receives USB data. The M66291 is mapped
to the /CS1 area (28000H ~ 3FFFFFH). The CPU and the M66291 are
connected as shown in the figure below.

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 POWEROFF time is short.)
3) The mode key switch is turned from OFF to a position other than
OF (excluding the SRV position). (If the power-off time is less than
5 seconds, the reset signal may not be issued.)

• Each position is correctly displayed.
• The brightness of each number is uniform.
• The buzzer sound is normal.

4.2. Test procedure
The keyboard is checked using the check sum code of the key code.
If the check sum code is not entered, the check is made using the
check sum code of the default keyboard arrangement.
The check sum 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.

NOTE: Calculation of key check sum data
Hard codes (hexadecimal number) at the position (excluding
feed key) where there is an input data contact are added.
However, the final key (CA/AT) is not added.
This data to which hard codes have been added is converted
into a decimal number value, which will become the check
