the printer display will still show "Toner Low" ?
Replacement chip for HP 9000 (cartridge
C8543X). The HP LaserJet 9000 HP cartridge C4583X (30K) cartridge
uses a smartchip. After the original toner cartridge
has emptied, the cartridge monitor will show "toner low" code
will be set to YES on the cartridge chip. Even after the cartridge
is refilled, the printer display will still show "Toner
Low". In order to overide the "toner low" message,
the chip on the cartridge needs to be replaced.
