SuppliesMax GSTC840-4PK Toner Combo Pack

The SuppliesMax GSTC840-4PK is a compatible toner cartridge combo pack containing one black, one cyan, one magenta, and one yellow cartridge. It is manufactured to OEM standards using new and recycled components in ISO 9001 and ISO 14001 certified facilities. Designed for 110V Gestetner Corp SP-C840DN and SP-C842DN colour laser printers sold in the U.S., it replaces the Gestetner Corp C840-4PK, 82125MP, and 82125BCMY part numbers. Use of compatible products does not void the printer manufacturer warranty.

For high-volume colour printing on supported

This pack suits offices and home users running Gestetner Corp SP-C840DN or SP-C842DN printers who need a full set of replacement cartridges for consistent, high-volume output. It delivers crisp black text and clear colour contrast at 5% coverage. Buyers with different printer models, those requiring MICR toner for cheque printing, or users operating on non-110V electrical systems should look at other options.

43000-page black yield at 5% coverage

The black cartridge yields approximately 43000 pages while each colour cartridge yields approximately 34000 pages at the standard 5% coverage rate. This high page count supports heavy daily workloads and reduces the frequency of cartridge changes. If your typical print coverage regularly exceeds 5%, or if you need a lower-yield pack for occasional use, the actual cost per page will differ from the rated figure.

Questions about this item

How often will I need to replace the black and colour cartridges in this combo pack?

The black cartridge yields up to 43000 pages at 5% coverage, while each cyan, magenta and yellow cartridge yields 34000 pages at the same coverage, so replacement timing depends on your colour-to-mono print ratio.

What page-yield limit will I hit first during continuous high-volume printing?

The colour cartridges reach their 34000-page rated yield before the black cartridge reaches its 43000-page rating, making colour the first limit under sustained use.

How much heat or noise does the printer generate when these cartridges run all day?

The cartridges themselves produce no heat or noise; thermal and acoustic output comes from the Gestetner SP-C840DN or SP-C842DN printer, which is designed for 110V operation.
