TM200 Service Manual

The cover open sensor is located next to the thermal printer mechanism, and it is connected via Door Sensor board assembly to the main circuit board unit. Detector signal INPUT_4 is input to the CPU.

Control Panel Control Circuit

This control panel is located on the mainboard. It has three LEDs (POWER, ERROR, PAPER) and one button (FEED). The POWER LED drives when +5V is supplied by the power circuit. The ERROR and PAPER LEDs are controlled by the CPU.

Drawer Kick Control Circuit

When signals KICK_OUT_X1 and KICK_OUT_X2 from CPU go active, it causes transistor array and outputting the drawer drive signal. The OPEN_CLOSE signal, which indicates whether or not the drawer is open, is input to the CPU, and this status can be obtained from the host interface.

Power Supply Circuit

The table as below shows supply voltage values and their applications.

+24V Control Circuit

The +24V power supply is split between the printer power supply and +5V. Then split into 3.3V and 1.8V.

+5V Control Circuit

A +5V regulator circuit switches the input +24V power supply and converts it to +5V. The switching regulator IC switches the input +24V, and +5V voltage is output.

The RS-232 power supply is generated by a charge up circuit built into the RS-232 interface’s onboard driver.
