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 receive a first write command from the controller of the image forming device. The chip is further configured to determine whether a transmission cycle bit of the first write command matches a transmission cycle bit of a second write command received by the chip from the controller of the image forming device previous to the first write command. The chip is further configured to resend to the controller of the image forming device a response to the second write command if the transmission cycle bit of the first write command matches the transmission cycle bit of the second write command.
