Questions about this item

How much power does the cartridge draw when the Gestetner SP-C840DN runs continuously?

The toner cartridge itself draws no power; the printer operates on a 110 V supply and the cartridge functions passively inside it.

Which printer models must I already own for this yellow cartridge to work?

It is compatible with Gestetner Corp SP-C840DN and SP-C842DN colour laser printers.

Will the cartridge work if I keep an older Gestetner 821256 or 821260 toner installed in another slot?

Yes, this SuppliesMAX cartridge replaces OEM part numbers 821256 and 821260 and operates alongside them in the same printer.
