Original Riso ComColor X1 PMS PCB

Part Number: 052‑75261‑000Alias: Paper Monitoring System PCB, BP Unit Sensor Control Board

Description

This is a brand-new genuine OEM PMS (Paper Monitoring System) PCB for the Riso ComColor X1 FORCEJET high-speed inkjet production printer. Installed inside the BP transfer unit, it collects signals from paper detection sensors, monitors paper arrival timing, sheet edge position, skew and paper presence. It feeds real-time sensor data back to the engine PCB to synchronise vacuum control, transport speed and jam detection, maintaining precise registration during continuous high-volume print runs.

Compatible Models

• Riso ComColor X1 Series: 3110, 3150, 7110, 7150, 9110, 9150

Key Features

✅ Genuine original Riso board, pre-calibrated for X1 BP transport timing 

✅ High sensing accuracy, minimises false jam alarms and missed sheet detection 

✅ Stable signal transmission, resistant to ink mist and temperature changes inside the BP compartment 

✅ Direct plug-and-play replacement; no hardware modification required

✅ Consistent sensing performance for long production cycles

✅ Matches original factory timing parameters for colour registration

Typical Faults This PCB Resolves

• Frequent false paper jam alerts with paper passing normally
• Undetected paper skew leading to misregistration
• Intermittent missing-sheet error codes
• Abnormal triggering of BP vacuum

• Timing mismatch between paper transport and printhead firing

  
  

Important Remarks

• This PMS PCB is dedicated to the ComColor X1 BP unit. It is not interchangeable with engine PCB, IP PCB or sensor boards from X3, FW, GD or HC series.
• ESD protection must be followed during handling and installation.
• No firmware flashing is generally required for this board, but clearing jam logs and running a sensor calibration after installation is recommended.
• Do not confuse this part with 050‑75056‑100, which is the BP transfer belt.
