Title: Image forming device, densitomer diagnostic system and diagnostic testing method
Inventor: ANTHONY JAMES D
IPC: G03G15/00
Filed: 2001-10-10
Abstract: PROBLEM TO BE SOLVED: To provide a diagnostic system for a densitometer used for an electrophotographic image forming device. SOLUTION: The image forming device with the densitometer diagnostic system has a photoconductor 1 or more chargers, an exposure device, the toning station and the densitometer. The densitometer diagnostic system for the image forming device has an emitter 224, a collector 226, an amplifier circuit 228 and a diagnostic circuit 230. The diagnostic system reduces the driving current flowing to the emitter of the densitometer 222 at a known or calculatable value. The output voltage from the amplifier circuit 228 in the densitometer 222 is decreased, in proportion to the driving current. The first output voltage is obtained from the densitometer 222, in a state with the diagnostic system being not connected thereto, in order to carry out the diagnostic testing of the densitometer 222.  The second voltage is obtained from the densitometer 222, in a state that the diagnostic is connected thereto. The densitometer 222 is functioning, when the first and second output voltages match with an output voltage reference value. The diagnostic circuit 230 is removable from the densitometer, when it is not in use. In turn, the densitometer may be provided with a switch for cutting off the diagnostic circuit, when it is not in use.
