XE-A40S Service Manual CHAPTER 3. MASTER RESET AND PROGRAM RESET [1] MASTER RESETTING Master resetting clears the entire memory and resumes default values. Master resetting can be accomplished by using the following proce- dure: 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 opera- tion.) [2] PROGRAM RESETTING (INITIALIZA- TION) 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. 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. 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.

1.2. Driving steps RECEIPT MOTOR * When stopping the motor, all energizing to the phase is turned off by giving the rush current of 10ms to the same phase as a final excitation phase. → Turn all RAS ~ RDS and JAS ~ JDS into L. No energizing should be allowed at lease 30 ms after stopping the motor before restarting. When the motor is started, the rush current of 10ms is given to the first excitation phase. 2. HEAD CONTROL 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 stable. (The power supply of the printer head should be turned ON and OFF by using the regulator IC.)

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. • 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 [6] POWER SUPPLY [7] RE-WRITING FLASH MEMORY [8] DRAWER The XE-A40S has a 1 drawer port. (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 ± 0.5kHz [12] USB I/F The XE-A40S is equipped with 1 USB port (slave) as a standard provi- sion. 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. Access from CPU to M66291 : 28000H + Register Address (00~77H) Input clock uses 24MHz. [13] 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.) 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.)

4. KEYBOARD TEST 4.1. Key operation 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. 4.3. Check: • The content of completion print 4.4. End of testing 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 sum data that will be entered when DIAG is started. 5. MODE SWITCH TEST 5.1. Key operation 5.2. Test procedure The above X must be read in the correct order. (If the contact is open, 9 will be displayed.) 5.3. Check: The display during testing and the content of the completion print. * At "OFF" position state, nothing is displayed after displaying 9. 5.4. End of testing 6. PRINTER SENSOR TEST 6.1. Key operation 6.2. Test procedure Check the status of the paper end sensor and head up sensor. 6.3. Check the following 6.4. End of testing You can exit the test mode by pressing any key and the printer prints the following. 7. CLOCK TEST 7.1. Key operation 7.2. Test procedure 7.3. Check that: "-" blinks and the clock counts up. 7.4.

The contents of memory must be stored before and after this test. RAM (08000H ~ 27FFFH area and 30000H ~ 4FFFFH area) is tested in the following procedure: 1) Store data in the test areas 2) Write "00H" 3) Read and compare "00H" and then write"55H" 4) Read and compare "55H" and then write "AAH" 5) Read and compare "AAH" 6) Restore stored data If an error occurs at a step, the error is printed. If any error does not occur, the following addresses are checked in turns. Addresses to be checked: 9.3. Check: • The completion print. 9.4. End of testing The program ends after printing as follows: When an error occurs, the printer outputs the error message and the address where the error has occurred in the area *****. 10. CPU INTERNAL RAM TEST 10.1. Key operation 10.2. Test procedure The test program tests internal RAM (10 Kbytes) of the CPU. The contents of memory must be stored before and after this test. RAM (00400H ~ 02BFFH area) is tested in the following procedure. 1) Store data in the test area. 2) Write "00H" 3) Read and compare "00H" and then write "55H" 4) Read and compare "55H" and then write "AAH" 5) Read and compare "AAH" 6) Restore stored data If an error occurs at a step, the error is printed. If any error does not occur, the following addresses are checked in turns. Addresses to be checked: 10.3. Check: The completion print. 10.4. End of testing The test program ends after printing.
