FP-740 Linear Encoder Board - 6700049050

6700049050 – Linear encoder board (FP-740 Linear Encoder Board) – Roland FP / SJ / XJ / XC

The 6700049050 linear encoder board (Linear Encoder Board) is an electronic component of the positioning system of the Roland large-format printers. It reads the carriage position via the encoder strip for a precise control of the X-axis movement.

This sensor board is key to the print quality: a fault causes banding or a print offset. Now discontinued by the maker, it remains available in a reconditioned or compatible version.
