HP FU5-3086-000CN 20-tooth pulley is a printer component intended for use in compatible HP printer assemblies. Its 20-tooth profile identifies this specific pulley variant and helps distinguish it from other pulley parts.
The distributor lists it for HP CLJ CM6030, CM6040, CM6049 and CP6015, as well as CLJ Flow MFP M880, LJ Enterprise M806 and LJ Ent Flow MFP M830. It is a small service part for restoring the pulley position in a compatible printer assembly.
