Black Genuine Toner Cartridge Standard Yield, 33,000 pages
The SD 4085 uses SHR SD-485NT (SHR SD485NT) and LAN 1170219 toner cartridges. SHR SD-485NT yields 33000 pages; LAN 1170219 yields 33000 pages.
The SHR SD-485NT cartridge has an approximate yield of 33000 pages.
Yes — the SD 4085 uses a replaceable imaging drum: SHR SD-485DR (SHR SD485DR).
A "Supply Problem" message on the SD 4085 usually points to a chip-communication hiccup rather than an empty cartridge. Power-cycle the printer (off for 30 seconds, then on), reseat the cartridge until it clicks into place, and gently clean the gold chip contacts with a dry cloth. If the message returns, a replacement SHR SD-485NT will clear it.
