1000018516 + 22565406 - Wiper motor (including pulley) Roland RF-640

1000018516 – Roland RF-640 wiper motor

The Roland SH1421-5042 motor – OEM ref. 1000018516 (also 22435106 / ‘103-593-1041’) drives the wiper system on the maintenance station.

Via its toothed pulley, it drives the mechanism that cleans the print head nozzles during maintenance cycles. A faulty motor prevents the print heads from being wiped correctly and impairs print quality.

Genuine Roland (OEM) part, supplied with its cable; bracket and toothed drive pulley (part no. 22565406) fitted, as shown in the photograph.
