Estimating the term…
A method and system are disclosed for detecting a fatal error condition in a printing device having an intermediate transfer member for facilitating toner transfer, including sensing a reflectance value of the intermediate transfer member at a first predetermined time; comparing the sensed reflectance value at the first period of time to a predetermined threshold; sensing a reflectance value of the intermediate transfer member at a second predetermined time after the predetermined first time; and comparing the sensed reflectance value of the intermediate transfer member at the second period of time to the predetermined threshold. If each of the sensed reflectance value at the first predetermined time and the sensed reflectance value at the second predetermined time is greater than the predetermined threshold, the method includes selectively suspending further printing operations until the imaging device is serviced.
An imaging device, comprising:
A method of diagnosing an error condition in an imaging device having an intermediate transfer member for transferring a toned image to sheets of media, the method comprising:
