Replacement Chip HP 4100, 9000

Each laser toner cartridge with toner chip has got a durability which depends on the toner chip ones. By changing this toner chip it gets back its maximum print capacity.

Exchanging your toner chip:
When your printer shows the message “Toner empty” you have to change your toner chip. Please note that in many cases after refilling your laser toner cartridge you can keep on printing without having changed the toner chip. For convenience we would recommend an exchange during the refill of your laser toner cartridge. Thus you avoid abrupt malfunction during the process of printing.
