OPC Drum — The OPC drum carries the latent image before toner transfer. Regular repeating marks on the page are a drum surface fault — the repeat distance identifies it.
This OPC drum produces sharp and consistent prints. It fixes light print, background blur and drum-related print defects.
For Konica Minolta BH184 OPC Drum fits HP P2035n, P2055dn, M401d, M425dn and 5 more listed below. Not suitable for: Machines where the fault originates in the developer or the transfer path. Match the part number to your machine before ordering.

If your machine is not listed, send us the model and a photo of the original part — parts that look alike within the same family are frequently not interchangeable.
| Symptom | Mechanism |
|---|---|
| Repeating marks at drum circumference intervals | Coating is damaged at that point |
| Background grey shading across the page | Coating is worn or light-fatigued |
| Vertical black lines | Surface is scratched |
| Light or faint print | Drum sensitivity has dropped |
Do not touch the coating with bare fingers and do not leave it exposed to room light — both leave permanent marks. Keep it in the sealed bag until the moment of fitting.
Q: Bare drum or complete drum unit?
A: Both are stocked. A bare drum is cheaper but needs a clean bench and care with the coating; a unit is faster to fit.
Q: What is the MOQ?
A: 200 pcs per part number.
Q: How is it packed?
A: Light-proof sealed bag inside an export carton.

Measure the repeat distance of the defect and compare it with the drum circumference. A defect repeating at drum circumference is on the drum. Streaking that varies with toner load points to the blade or the developer instead.
Check for light exposure and fingerprints first — both ruin a coating immediately. If the drum was stored outside its sealed bag under room light, it may already be degraded before fitting.
