1715360 - Epson carriage tensioner pulley and belt

PULLEY, DRIVEN UNIT, 44, D, ESL, ASP

The PULLEY, DRIVEN UNIT, 44 (part number 1715360) is the driven pulley and toothed belt assembly that drives the print carriage on Epson Stylus Pro 44-inch plotters. It is supplied fully assembled, with the belt and pulley bracket integrated as a single unit.

The driven pulley, positioned at the end opposite the CR motor, guides the belt and absorbs the tension in the return run. The consistency of this tension directly affects the precision of droplet positioning and, consequently, the quality of bidirectional printing.

This part number replaces the previous versions 1695177, 1587841 and 1504213. Replacing it restores the equipment to its original performance.

Component function

- Transmits torque from the CR motor to the print carriage via the toothed belt -
Guides the belt back to the end of the rail and maintains its
alignment - Ensures and stabilises belt tension across the entire print width
- Absorbs jolts during acceleration and when the
carriage changes direction- Ensures repeatable positioning of the carriage along the rail
