Appendix 1. Technical Background
The toner bottle ID chip has a counter that counts the number of failed attempts to
resupply the toner from that bottle. This counter counts up when the machine cannot
resupply the toner from the bottle.
The machine is designed not to attempt to resupply the toner from the bottle which has a
counter of more than 2 attempts of resupplying failure. This is to protect the pump: The
pump used in Taurus is called progressive cavity pump, which can get damaged if it runs
without toner (dry run condition).
By applying the firmware, the machine will attempt to resupply the toner even the counter
is more than 2 attempts. The replaced failed new toner bottle, able to use it for print, but
as for the trade off, the pump will run under “dry run condition”; therefore the risk for the
pump failure will increase.
