Compatible Black Toner for Gestetner C7640 Series

This SuppliesMax cartridge replaces Gestetner part numbers 820000, 87830 and 87800 in the C7640 and C7640ND printers. It is a new aftermarket unit built to OEM dimensions for direct installation. The single black cartridge supports everyday business and personal printing tasks. Buyers with non-Gestetner machines or colour-only printing needs cannot use this item.

Yield measured at five percent coverage

The quoted 23000 pages assume the ISO standard five percent page coverage. Pages with heavy graphics, solid fills or frequent duplex runs will reduce the actual page count proportionally. The cartridge is designed for 110V printers sold in the U.S. market. Environments requiring higher coverage or different voltage standards will see different results.

Twenty-three thousand page rated capacity

This yield figure is the primary specification for matching the cartridge to your print volume. It determines how often the cartridge must be replaced in a given workflow. The unit is manufactured in ISO 9001 and ISO 14001 certified facilities and carries a thirty-day manufacturer warranty. Shops needing a higher or lower rated yield should select a different cartridge.

Questions about this item

Should I pick the 23000-page cartridge or a lower-yield option for my Gestetner C7640?

The 23000-page yield at 5% coverage suits high-volume printing; choose a lower-yield cartridge only if your monthly output is light and you prefer more frequent changes.

What does the 23000-page figure mean once the cartridge is in my C7640ND?

It represents the approximate number of pages at 5% coverage; graphics-heavy pages will reduce the actual count while text-only pages may extend it.

Which OEM part numbers does the SP-C811DNHA cartridge replace and what does that cover?

It replaces Gestetner 820000, 87830 and 87800, covering black toner for the C7640 and C7640ND series printers.
