Drum units: the assembly your print quality rides on
Streaked, grey or ghosted copies are symptoms to work through in that model's own diagnostic sequence: the imaging surface this unit carries is one candidate, and fixing-side causes sit alongside it until the sequence separates them. Guangzhou Xinxiangyin lists drum units （鼓组件/套鼓） as a core line of its copier parts range, alongside the standalone OPC drums for dealers who rebuild units themselves.
Drum units are bought by machine model, full stop. The verified cartridge families in this catalogue — Canon, Toshiba, Kyocera, Konica Minolta, Ricoh, Xerox, Sharp — are the families to enquire against: state the copier model and the unit is quoted against it. OPC drums and blades are separate lines of this catalogue, each confirmed for the model on the enquiry.
Two ways to buy: unit or components
- Complete drum units — the assembly form: the unit is bought as one part, by machine model.
- Components — OPC drums, cleaning blades and charge rollers are listed as separate lines on the parts shelf, each quoted by machine model, for buyers who rebuild units on their own benches.
Both forms are in this catalogue — complete units on this page, and the component lines on the parts shelf. The MP1350 OPC drum on the next page is the documented example, a single drum specified against an eight-model Ricoh production fitment list.
What to put in a drum unit enquiry
Three things: the copier model (from the machine's plate, not the brochure), whether you want complete units or rebuild components, and the quantity per model. Mixed enquiries — cartridges and drum units for the same installed base — are welcome; whether the lines travel together is confirmed on the quotation for that order. If a machine is mid-contract and quality is drifting, say so in the enquiry: the answer may be a drum and blade set rather than a full unit, and you can ask for both routes to be priced against the model.
How do I know the drum unit, not the toner, is the problem?
Defects that repeat at the drum's rotation interval put the drum itself among the candidates. Background shading that a new cartridge does not cure, and quality that fades across a cartridge's life, put the imaging side among the candidates rather than settling it; work through the model's own diagnostic sequence to confirm which part. Where you have a known-good cartridge that fits that model to hand, a test swap can help show whether the fault sits on the toner side.
Do you sell drum units for every cartridge family on this site?
Drum units are a listed core line of the parts range. Availability is confirmed per copier model on your enquiry — the catalogue lists what is verified, and unit fitments are quoted model by model.
Can I buy just the OPC drum for a unit I already stock?
Yes — standalone OPC drums are the next page, including the documented MP1350. Blades and charge rollers are on the parts shelf.
What wears out first in a drum unit?
There is no fixed order that holds for every machine — inspect the drum surface, the cleaning blade edge and the charge roller, and replace what the inspection condemns. In a rebuild, inspect the blade while the unit is open: if its edge is worn or nicked, change it in that same opening rather than leave a worn edge running against a fresh drum surface — the maker's procedure for your model governs the interval.
Put drum units on the contract calendar
Drum wear is gradual: the background greying and repeat marks described on the cartridge vs drum unit guide creep in as the surface ages. A service contract can plan around that slide: drum life tracked per machine the same way toner is tracked, expected replacement windows noted against each installed model, units or rebuild kits ordered ahead of the window, and the swap folded into a routine visit — a planned line on the service calendar instead of an emergency part.
Quote drum units by copier model
Send the cartridge or part numbers you buy now, the copier models they go into and your destination port. Ask for the quotation model by model, with the packing details for your order. On the company's Alibaba storefront, recent listings show cartridges starting from as low as 1–12 pieces and toner from 1–2 bags, so a trial order does not need a container behind it.
