Module Combinations and Specifications
The EU-T532/T542 can be used as four different types by the module combinations. The module 
combinations, functions and specifications are as follows:
(*): The printer pulls a cut sheet that has been forgotten in the printer and ejects it to the lower part of the cut 
      sheet presenter module. Environmental condition Operating temperature 0 to 50°C
Operating humidity 10 to 80% RH

Operation Principles
Outline of Mechanism
The EU-T532/T542 consists of four modules: the paper roll supply module, the printer module, 
the cut sheet presenter module, and the control circuit board module.
Paper Roll Supply Module
The paper roll supply module holds a large diameter paper roll and guides the paper to the 
printer module. This module consists of the paper holding part, the paper load-absorbing...

Paper Holding Section
The paper roll holding mechanism is a shaft support type. The paper roll holding section 
consists of the shaft, paper roll 
fixed to the frame, main assembly
, the holder, paper roll A
 
(for the inner diameter of the paper core: 25.4 mm {1 inch}) that fits the size of the paper roll core 
used, and paper roll hold unit
 that holds the sides of the paper roll. 
The paper roll hold unit
 is supported by the holding plate, paper roll
 so...

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.

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
. 
When the motor, paper feed, receipt, B...

Platen-open mechanism
The platen-open mechanism is used for the following purposes:
•  Paper loading when using the printer with the curved path type. (Excluding when 
using semi-autoloading mode.)
• Removing a paper jam when the paper jam has occurred
• The thermal head
 and the platen

Printing Mechanism
This mechanism consists of the thermal head
 which has the head heating elements arranged in 
a series and has a driver IC for controlling voltage to the head heating elements, the platen
 
which is also used for the paper feed mechanism as well as this mechanism (the thermal head
 
is also used for both mechanisms), and the spring, press head
. The platen
 presses the thermal 
paper wrapped around the platen
 against the head heating...

Data input and printing
The thermal head
 consists of the head heating elements, the head driver, which controls or 
drives the head heating elements, and the thermistor
, 
which detects the temperature of the 
thermal head
. The serial print data input from Data In (DI1) is synchronized to the CLOCK 
(CLK) input, and temporarily placed in the SHIFT REGISTER. Using the LATCH (/LAT) signal 
timing, these data are then stored in...

Paper Guide Mechanism
This mechanism consists of the paper guide mechanism. The paper path consists of the paper 
guide, straight, front 
and the paper guide, straight, back
. The paper path is shown below.

Detector Mechanism
This mechanism consists of the paper-end mechanism, the platen-open detector mechanism, the 
head temperature detector mechanism, and the black mark detector mechanism.
Paper-end detector mechanism

The transparent photo
 sensor is in a high state (HI) when the paper is present, and in a low 
state (LOW) when the paper is not present because the lever, paper detector
 blocks light to 
the sensor. When the end of the thermal paper passes through the paper guide, the lever, 
paper detector
 operates as shown in Figure 2-11. At this time, the output level from the 
transparent photo sensor
 varies as shown in Figure 2-12, then...
