  • Page 14: Printer Module

    Confidential EU-T432 Technical Manual Printer Module The printer module has a printing mechanism with the paper feeding and a cutting mechanism to cut the paper. The printer consists of the following six mechanisms: the drive force transmission mechanism, the paper feed mechanism, the printing mechanism, the paper guide mechanism, the detector mechanism, and the autocutter mechanism.

  • Page 15: Paper Feed Mechanism

    Confidential This printer uses a 4-phase bi-polar stepping motor driven by 24 V voltage controlled 2-2 phase excitation. The maximum drive frequency of 2-2 phase excitation is 1200 pps. [pps: pulses per second] Paper Feed Mechanism This mechanism consists of the paper feed mechanism and the platen-open mechanism. Paper feed mechanism The paper feed mechanism consists of the platen (paper feed roller) and the thermal head.

  • Page 21 Confidential Platen-open detector mechanism The platen-open detector mechanism has a microswitch which detects whether the platen is open (printing impossible because the thermal head is away from the platen) or closed (printing possible). The microswitch can be OFF only when the frame, platen is perfectly closed, and at all other times is ON.

  • Page 22: Autocutter Mechanism

    Confidential EU-T432 Technical Manual Black marks are detected through changes in output level from the reflective photo sensor. The changes in reflectivity between the pre-printed black marks and blank areas of the thermal paper cause the amount of light returning to the sensor to vary; then the sensor output level is also varied as shown in Figure 2-15.
