TM200 Service Manual 2 Mechanisms and Operation 2.1 Component Connections This printer is made up of the following major components: TM200 printer mechanism (switch circuit board assembly) I/F circuit board assembly Main circuit board unit 2.2 TM200 Printer Mechanism This printer consists of three mechanisms: a printer mechanism and a cutter module. The following illustration shows the external configuration of the TM200. Figure 2.
TM200 Service Manual Printer Mechanism Thermal head Module The thermal head is designed so its heating element is positioned where it comes into contact with the platen. The roll paper wrapped around the platen is kept in contact with the thermal head’s heating element at a prescribed pressure, and printing is performed when heat is generated by the heating element. Printing is performed according to the following steps: 1.
TM200 Service Manual Autocutter Module This printer is equipped with an autocutter module for cutting of the roll paper and a manual cutter for manual cutting. The autocutter has two opposing cutter blades that operate like a scissors to cut the paper. It is a separate cutter blade-type mechanism that does not require passage of the roll paper through an autocutter mechanism slit. Opening the frame cover causes the stationary blade to separate completely from the moving blade.
TM200 Service Manual CPU peripheral logic circuits RAM (128K byte) RAM is used for temporary storage of the following: Data received from the interface (receive buffer) Pattern data printed by the print head unit (printer buffer) Data used for CPU routines (flags, pointers, etc.) Flash memory (2M or 8M bits) A printer control program and character generator data is written into flash memory.
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.
