2PCS New Original Roland SENSOR-INTERRUPTER 1000006689 for FH740, EJ640, LEC-540, LEC2-300, LEF-20

This 2-piece pack of New Original Roland SENSOR-INTERRUPTER (PN: 1000006689) is the official photoelectric interrupter sensor for a wide range of Roland printers and UV flatbed machines, including FH740, EJ640, LEC-540, LEC2-300, and LEF-20. It is a critical component for detecting the position of the print carriage, media feed, or mechanical parts, ensuring accurate movement and reliable operation of your Roland device.

As a genuine Roland OEM sensor, it features high-sensitivity optical detection and a rugged construction that resists dust, vibration, and wear—common causes of sensor failure in busy production environments. A faulty interrupter sensor often leads to "media jam" errors, incorrect carriage positioning, or even machine shutdowns, disrupting workflow and causing costly downtime. This direct-replacement sensor is pre-calibrated, requiring no adjustments upon installation, and restores your machine’s positioning accuracy to factory standards.

The convenient 2-pack allows you to keep a spare sensor on hand for quick replacement, making it an essential maintenance part for print service providers, sign shops, and in-house production facilities using Roland’s FH, EJ, LEC, or LEF series equipment.

🔧 Installation Guide (10–15 Minutes, Basic Tools: Screwdriver, Tweezers)

⚠️ SAFETY FIRST: POWER OFF | UNPLUG AC CORD! Disconnect all cables before servicing. WEAR ANTI-STATIC WRISTBAND to prevent ESD damage to the sensor.

1. Power off the machine and unplug the power cord. Locate the faulty sensor (typically mounted on the carriage rail, media feed unit, or inside the machine near moving parts).
2. CRITICAL : Take clear photos of the sensor’s wiring (connector orientation) and mounting position for reference.
3. Using tweezers, gently disconnect the electrical connector from the old sensor.
4. Remove the mounting screw(s) (Phillips head) securing the old sensor to the chassis. Carefully lift the old sensor out.
5. Unpack a new Roland 1000006689 sensor. Align it with the mounting holes and secure it with the original screw(s) (do not over-tighten).
6. Reconnect the electrical connector exactly as shown in your photos—ensure it clicks into place securely.
7. Reconnect the power cord and power on the machine.
8. Perform a Carriage Test or Media Feed Test to verify the sensor works correctly—no error messages, smooth movement, and accurate positioning.

💡 PRO TIP: Clean the sensor’s optical slot with a dry lint-free cloth before installation to remove dust or debris, which can interfere with detection. Keep the 2nd sensor as a spare for future maintenance.
