Specifications

• Type: Junction-to-Panel cable assembly (OEM)

• Printer Compatibility: Roland VersaUV LEF-20 only

• Function: Carries panel key matrix, LED/buzzer, and display signals between panel PCB and junction/main board

• Construction: Factory-terminated ribbon / FFC-FPC or mixed harness (revision dependent)

• Connectors: Keyed, board-matched plugs; latch or friction-fit (per revision)

• Electrical: Low-voltage logic pass-through (5 V signaling typical)

• Length / Pinout: Model-matched; verify against your serial range/revision

• Packaging: Anti-static bag with protective caps as supplied by OEM

• Replaces: Roland part 1000011659

Highlights

• OEM Fit: Correct length, pinout, and connector orientation for the LEF-20.

• Signal Integrity: Clean, reliable panel communications to prevent false keys and display glitches.

• Service Friendly: Pre-terminated, plug-and-play—no crimping or soldering required.

• Downtime Reducer: Fast swap to resolve intermittent panel faults caused by worn or bent cables.

Use & Details

• Use Cases: Replace cut/kinked ribbons, fatigued conductors in the cable chain, or corrosion/oxidation on contacts causing panel dropouts.

• Installation Notes:

  • Power off and unplug printer; observe ESD precautions.

  • Photograph routing before removal; avoid sharp bends and twists.

  • Insert FFC fully and lock latches; match keyed orientation—do not force.

  • After install, run panel key/display test and confirm stable operation.

• Troubleshooting Clues: Stuck/ghost key presses, random menu jumps, dead LEDs/buzzer, or flickering/no display after ruling out the panel PCB and main board.

• Compatibility Checklist: LEF-20 model → part 1000011659 → connector style/pitch → required length → board revision/serial range.

• Care & Handling: Keep contacts clean; store in anti-static packaging; maintain generous bend radius during routing.
