6. CIRCUIT EXPLANATION
6-1. Power supply circuit
Q1 : Transistor for controlling voltage (VP)
Q2 : Transistor for voltage detection
Q3 : Transistor for controlling power down (PWD) signal
ZD2 : Zenner diode for controlling base current of Q2
ZD3 : Zenner diode for detecting power down (PWD) signal
After plugging the AC cord into the outlet, the AC voltage (23.8 V) appears at CN1 connector.
Then this voltage is rectified by the diode bridge and it become constant voltage through the capacitor
C1.
[Voltage VP]
A constant voltage (31.4 V) appears on the "2" position. This voltage made from the constant
voltage circuit consist of transistor Q1 and Q2, zener diode ZD2, resistor R7, R8, R12 and R13.
[Voltage VLED and VCC]
The voltage goes to pin No.1 of regulator IC1 and then it is out from pin No.2 of IC1 as stable
voltage (5.6 V).
Then this voltage falls down to 5 volts through the diode.
It is used for VCC (for logic) and VLED (for display drive).
Also, it goes to pin No.4 of IC1 and using to control the output voltage level.
Inductor L1 is used to stabilize the VCC voltage when the drawer opened.

[PWD signal]
After plugging the AC cord into outlet, VP voltage appears on the base terminal of transistor Q3.
When the VP exceeds 16 volts, Q3 is turned on by the differential voltage between base and
emitter terminal of transistor Q3.
Then the PWD signal goes to GND level and informs "Power ON" to the CPU.
When the VP drops less than 16 volts, Q3 is turned off.
Then the PWD goes high level since the PWD is pulled up to VDD.
When the CPU receives "High" signal of PWD, CPU goes to "Power failure process".
Note:When plugging the AC cord into outlet, all voltages are supplied to the PCB.
If you open the machine for repair, make sure to unplug it.

level
To Printer To CPU
Note:The "PW-ON level" is measured under following conditions.
(1) Mode switch is REG position.
(2) The display is the time.
(3) Receipt switch is ON position.
(4) PAD1 and PAD2 are both open.
6-3. Motor error detection circuit
When CPU output motor signal, transistor Q8 becomes on and the voltage level at "A" point becomes
GND. Then, paper feeding motor rotate. Normally, pin No. 1 of IC4 appears low signal.
IC4 detects differential voltage between pin No. 2 and 3.
In case pin No. 3 is higher than No. 2, output (pin No. 1) signal is high.
If motor happens over load (paper jam etc.), over load current (250mA) runs resistor R9. So " A" point
voltage level becomes high.
Then IC4 outputs high signal and then CPU knows motor error occured.
Whe the CPU receives "Motor error signal" CPU stops motor signal.

6-5. RAM address/head drive signal switching circuit
The CPU uses the port for RAM address (A0 ~ A11) and head drive signal (HD1 ~ HD6).
To select the RAM address and head drive signal, CPU use "STEP MOTOR COM" signal.
When CPU wants to read the RAM chips, CPU stops "STEP MOTOR COM" signal.
The CPU controls RAM address (A0 ~ A12) using IC 10 because CPU has 7 ports.
First, CPU sends RAM address (A4 ~ A7, A10, A11) to IC10 and IC10 store the address data.
Next, CPU sends RAM address (A0 ~ A3, A8, A9, A12, A14) to RAM.
At the same time, CPU sends clock signal to IC10.
Then, IC10 outputs stored data (A4 ~ A7, A10, A11). In this way, CPU controls RAM address.
