Abstract
A toner container installable in an image forming device having a controller according to one example embodiment includes a housing having a reservoir for storing toner. A chip is positioned on the housing and configured to, after sending a first busy response to the controller of the image forming device, receive a second write command from the controller of the image forming device that is abbreviated relative to a first write command received from the controller of the image forming device and that requests the chip to send a response to the first write command. The chip is further configured to send a response to the first write command to the controller of the image forming device if upon receiving a read command corresponding to the second write command the chip has completed processing the first write command.
