Why choose the genuine OKI ES8434 imaging drum
The drum (photoconductor) lays the toner onto the sheet; it is a wear part separate from the toner and outlasts several cartridges. A genuine OKI drum keeps sharpness and avoids marks repeated at regular intervals; the printer tracks its wear and signals replacement.
The other colors of the series
The 46857521 comes in the following colors, ordered separately as each one wears out: 46857524 (black), 46857523 (cyan), 46857522 (magenta).
Printers compatible with the 46857521
The list of compatible printers is not available for this reference. Check the reference of your current consumable in the printer's manual or menu: it must match 46857521 exactly.
If in doubt, send us the exact model of your printer and we will confirm compatibility.
Installation
Tool-free replacement: open the cover, remove the used assembly, unpack the new drum without touching the green surface or exposing it to light for long, refit and close. Follow the guide to reset the counter if the printer asks for it.
Use and tips
The 46857521 drum is replaced far less often than the toner. The printer's counter tracks its wear and warns ahead of time.
Keep the drum in its packaging until installation; do not touch the green surface and limit exposure to light. Marks repeated at regular intervals or a gray background: replace the drum, not the toner.
