Genuine OEM Lexmark C748 E Toners
For the Lexmark C748e, a photoconductor change is a separate job from changing toner. Lexmark says to change all four photoconductors together when prompted, then reset the maintenance counter. The C734X24G kit groups those four units in one pack.
Toner Buzz carries genuine Lexmark toner individually and in black-and-color sets, with C746 and C748 cartridge choices. Photoconductor packs, waste toner collectors and fusers cover the separate maintenance needs, while individual toner cartridges let you select a particular color.
