Page 50 NOTE ● If a large current (such as welding current of a welder) flows from the outside through the frame ground, the current may also flow around the signal ground, which may damage the printed circuit board or melt the ground wire. Therefore, when performing welding work near the IJ Printer, follow the method below regardless of whether it is in operation.
Page 51: Connecting Input/Output (I/O) Signals
4.2. Connecting Input/Output (I/O) Signals Lead the I/O lines from the I/O cover lead-in port on the back of the unit, and connect them to the internal terminal blocks and external communication connectors. CAUTION ● Turn the power off before wiring. Usually, use the unit with the top and I/O covers closed.
Page 52 NOTE ● Use a cable whose outside diameter is within the specified range. Securely tighten the lock nut at the lead-in port. In addition, do not bundle cables of weak and strong electric systems inside or outside the unit, in order to minimize the influence of noise from strong electric system signals (connection signals to the power supply and terminal block TB5) on weak electric system signals (connection signals to terminal blocks TB1, TB2, and external communication connectors).
Page 53: Connecting To Input/Output (I/O) Terminals
4.2.2. Connecting to Input/Output (I/O) Terminals NOTE ● Check terminal signals for secure wiring. Incorrect wiring may cause a board failure.

Page 59: Print Target Detector Input
4.3.1. Print Target Detector Input The print target detector input function is used to input the start print signal of the IJ Printer. Use a no-contact (transistor) type output for the print target detector. An optoelectronic sensor with built-in amplifier that detects a print target with an optical beam is the most suitable.
Page 60 (2) Specifications of the print target detector (a) When the NPN interface is used ● Internal circuit diagram The input circuit of the IJ Printer is a current drive load to the output circuit of the print target detector, and when the output transistor Tr of the print target detector is switched on, it becomes an input of the start print signal.

Page 63: Speed Matching Function Using Rotary Encoder
4.3.2. Speed Matching Function Using Rotary Encoder The speed matching function is used when the speed of a print target or the speed of the conveyor carrying the target changes while printing is in progress in the IJ Printer. Without this function, a change in the speed may change the width of characters to be printed, causing the difficulty in reading them.
Page 64 (2) The figure below shows the encoder wiring and the SW1 setting on the EZJ144 board at the use of the IJ Printer built-in power supply. (a) When open collector output and the IJ (b) When totem pole output and the IJ Printer Printer built-in power supply are used.

Setting to IJ printer Make the [Product speed matching] and [Pulse rate div. Factor] settings on the [Print specifications] screen (See "5.6.
Page 66 4.3.2.3. Calculation of Conditions that Allow Product Speed Matching Calculate whether the ink drop use and division factor can meet the conditions that allow product speed matching, based (1) to (7) below. Perform the calculations below. The lower the ink drop use is, the better the print quality is.
Page 67 ● When the [Product Speed Matching Error] warning alarm is set, an alarm occurs. In this case, decrease the conveyor speed, increase the print character width, and increase the ink drop use to make the maximum value of the print scan frequency smaller than the value obtained by the formula 3 (to make the set print speed of the IJ Printer faster than the highest conveyor speed).

Page 71: Input Function
4.3.3. Input Function You can control the IJ Printer by inputting print stop and remote operation (startup, stop, fault reset, and deflection voltage control) to the pin numbers 4 and 5 on the terminal block TB1 and the pin numbers 14 to 18 on the terminal block TB2 via an external switch or contact signal.

Page 74 (ii) The time t3 between the input of deflection voltage control and the change of the state is within three seconds. (standby => ready) t4 is within 100 ms. (ready => standby) (iii) You need to check the state before switching deflection voltage control on. If you switch deflection voltage control on during printing by mistake, the unit stops the printing halfway and switches from the ready state to the standby state even in the process of printing.
Page 75 (e) Stop signal After switching the stop signal on, check that the IJ Printer is in the stop state, and then turn the power off. It takes about three minutes from switch-on of the stop signal to entering the stop state. (ii) The time t6 between the input of the stop signal and the change of the state is within 100 ms.
Page 76: Output Function
4.3.4. Output Function Monitor the states of the IJ Printer by connecting the print output (print-in-progress or print-complete), online output, ready, fault, and warning signals to the pin numbers 10 to 23 on the terminal blocks TB1 and TB2. Monitor the ready, fault, and warning output signals by connecting no-contact (transistor) output or contact (relay) output to the pin numbers 1 to 9 on the terminal block TB5 *TB5 is optional parts.

Page 78 4.3.4.3. Ready Output (Output via NPN/PNP Interfaces: Pin Number 10 on Terminal Block TB1, Relay Output: Pin Numbers 1 to 3 on Terminal Block TB5 *TB5 IS OPTIONAL PARTS.) The ready output provides a function that outputs a signal to the outside indicating that the IJ Printer is in the ready state.
Page 79 Each of NO and NC contacts supports a capacity of up to 30 VAC/0.5 A or 30 VDC/1 A. For the use of the unit under a load larger than the capacity, interpose another relay in the connection. When the load is an inductive load such as a motor or a relay, counter electromotive force may be generated, which may shorten the life of the contact.
