PROGRAM RESETTING (INITIALIZATION) Master resetting clears the entire memory and resumes initial values. This resetting resumes the initial program without clearing memory. Master resetting can be accomplished by using the following procedure: This resetting can be operated at below sequence in PGM mode. Procedure A: 1) Unplug the AC cord from the wall outlet. Procedure: 1) Unplug the AC cord from the wall outlet. 2) Set the mode switch to the PGM position. 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. 3) While holding down both JOURNAL FEED key and RECEIPT FEED key, plugin the AC cord to the wall outlet. The master reset can also be accomplished in the following case. 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. 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 memories are lost and the machine does not work properly after power recovery; this requires the master reset operation.)

The RESET signal is canceled when the power source of the device which used the 5V system (VCC, VDD, VLED) reaches the operating voltage. <CPU’s PORT> No. CPU PORT Signal name FUNCTION 97 AN0 TM PRINTER HEAD temperature monitor 95 AN1 VPTEST 94 AN2 VREF Refarence voltage 93 AN3 VBAT VBAT (Battery voltage) The RESET signal is generated under the following conditions. 1) When the mode key switch is set from SRV' to another position (except for OFF position). PRINTER HEAD voltage monitor 2) When the power is turned on after 5sec or more from turning off the power and the VCC reaches 5V. 1 Printer head temperature monitor A voltage divided by the printer head temperature monitoring thermistor and the resistor is inputted to AN0 pin. Printer head conduction must be controlled as shown below. For the printer head conduction time, refer to the M-T53II specifications. 3) When the mode key switch is set from OFF position to another position (except for SRV’ position) and VCC reaches 5V. (If the OFF time is within 5sec, the RESET signal may not be supplied.) 12. POFF The POFF signal is changed from 0 to 1 when the 5V power and the 24V power reach the operating voltage level. When they fall below the operating voltage level, the POFF signal is changed from 1 to 0.

The A/D conversion value is read after turning the VPON signal (CPU P105) to HIGH and stabilizing the voltage (20msec). The print enable voltage range is 7.5V ~ 8.0V (A/D value: ??? ~ ???). The voltage is calculated from the AN1 value and the A/D conversion value of the AN2 reference voltage. For the calculation method, refer to the M-T53II specifications.
