Kyocera DV-3100 (302LV93082) is a developer unit listed for the ECOSYS FS-4300DN. It is a printer component associated with the development system, and Kyocera identifies this specific part number as DV-3100.
Kyocera's service bulletin records a change to the material of the cleaning sheet for the unit's DS pulley. It also identifies 302LV93082 as the successor to 302LV93081. The bulletin lists separate China and Korea versions, so this part reference denotes the standard DV-3100 variant rather than those regional versions.
