How to Choose an Encoder for a TIJ Printer: Selection Guide, Local Purchase & Installation

1. Why Do You Need an Encoder for TIJ Printers?

In Thermal Inkjet (TIJ) printing applications, an encoder is a critical peripheral for ensuring high-quality output.

In high-speed packaging lines, conveyor speed fluctuations can cause printed codes to stretch, shrink, or distort. An encoder measures conveyor movement in real-time and sends pulse signals to GORGEOUS TIJ Printers, ensuring consistent print lengths regardless of belt speed changes.

2. Key Selection Guide（Example: GORGEOUS TIJ Printers are equipped with a 2000 PPR encoder）

Many customers mistakenly believe that the higher the pulse count, the better. In reality, the key is to choose the pulse parameters that best match the machine.

Choose the most suitable synchronizer based on the manufacturer’s recommendations, rather than blindly pursuing higher pulse parameters.

3. Local Purchasing Guide

If you need an encoder urgently and wish to avoid international shipping delays, you can easily source one locally. Use the following search keywords:

• Incremental Rotary Encoder 2000 PPR NPN Open Collector 5V
• 2000 PPR Encoder Wheel 200mm with Spring Mounting Bracket
• 4-Pin Aviation Plug NPN Speed Synchronizer for TIJ Printer

4. GORGEOUS Pinout & Wiring Diagram

For GORGEOUS TIJ Printers with 4-pin aviation plug and NPN open collector circuit (5V, Max 150mA per channel), strictly follow this pinout:

Adaptation Step-by-Step:

Step 1 : Confirm wire colors: Brown（5V）, Blue（0V）, Black（Signal A）, White（Signal B）.

Step 2 : Solder or screw the wires into the 4-pin plug pins matching numbers 1, 2, 3, and 4 respectively.

Step 3 : Insulation protection: Wrap solder joints with heat-shrink tubing to avoid short circuits.

Step 4 : Mount the encoder bracket on the conveyor frame so the 200mm measuring wheel contacts the belt smoothly.
