W701588450 - Assy Linear Encoder LEJ-640

W701588450 – Linear encoder assembly (Assy Linear Encoder, strip + mounts) – Roland LEJ-640

The W701588450 linear encoder assembly is an essential part of the positioning system of the Roland LEJ-640 UV flatbed printer.

It is made of the encoder strip and its mounting parts and allows the precise reading of the carriage position on the X axis. It ensures a perfect alignment of the print passes and a faithful reproduction of the visuals, even at high resolution. The encoder strip is sensitive to UV inks, dust and residue: a regular cleaning is recommended before replacement.
