Technical Specifications
Uninet® Lexmark Optra® S encoder wheel transforms your low-yield versions (250
grams) of the 4059 back in service by converting them into high-yield, 500 gram
units.
The wheel features precision windows around the perimeter that are read with an
optical sensor, telling the printer the identification of the cartridge as
either a 7,500 page or 17,600 page capacity type, and delivering feedback to the
printer's firmware indicating the approximate print pages remaining in the
cartridge.
NOTE: Lexmark prebate wheel
