Abstract
Image forming devices are described comprising a humidity indicator, a scanner to optically scan the humidity indicator, a processor, and a non-transitory computer readable medium storing computer-executable instructions that when executed by the processor cause the processor to instruct the scanner to initiate an optical scan of the humidity indicator, determine a humidity level based on the optical scan of the humidity indicator, and instruct the image forming device to adapt a behavior characteristic of the image forming device responsive of the humidity level.
