The AL 840 uses 12 toner cartridges, including SHR JX-92NT, SHR FO-26ND and SHR UX-36ND.
CTC FO-26ND prints 2000 pages, SHR JX-92NT (SHR JX92NT) prints 20000 pages. Choose SHR JX-92NT (SHR JX92NT) for high-volume printing (lower cost per page); CTC FO-26ND costs less upfront for occasional use.
The SHR JX-92NT cartridge has an approximate yield of 20000 pages.
For SHR FO-26ND you can choose Genuine Sharp (SHR FO-26ND (SHR FO26ND)) or a Remanufactured option (CTC FO-26ND) at a lower price per page, same 2000 page yield.
Yes — the AL 840 uses a replaceable imaging drum: SHR AL-80DR (SHR AL80DR), SHR UX-36DR (SHR UX36DR).
When the AL 840 throws a "Supply Problem" error, the printer often simply can't read the cartridge chip. Give it a full power-cycle, take the cartridge out and put it back securely, and lightly buff the metal contacts with a dry, lint-free cloth. If it persists after all that, the cartridge is likely worn — install SHR JX-92NT.
