W701986060 - ASSY,THERMISTOR BOARD RE-640

Assy, Roland RE-640 / VS-640 / VS-640i Thermistor Board — Part No. W701986060

The Thermistor Board W701986060 is the original Roland thermal measurement board integrated into the RE-640, VS-640 and VS-640i printers. It features thermistor sensors that continuously measure the temperature of the machine’s heating elements (media preheating, drying heat) and transmit this data to the main control board. This information enables the system to precisely regulate the temperature to ensure optimal ink fixation and consistent print quality.

This part is compatible with thermistor boards W701406060 (VS-640) and W702406060 (VS-640i). A faulty thermistor board can cause temperature errors, overheating alarms, incorrect temperature regulation or an emergency shutdown of the machine.
