Abstract:
1. A method of detecting an event in an image forming device, the method comprising: transporting a substrate along a transport path of the image forming device by a substrate transport unit of the image forming device; forming an image on the substrate by an image forming module of the image forming device; detecting the event in the image forming device and providing an event signal along a signal path by an event sensing module of the image forming device in response to the event; providing signal pulses different than the event signal along the signal path by a signal generation module of the image forming device; determining a presence of the event signal and an absence of the signal pulses by a signal detection module of the image forming device; providing at least one of a visual alert and an audio alert to a user by an alert unit of the image forming device in response to a determination of the absence of the signal pulses and moving the image forming module from a first position to a second position by a repositioning module of the image forming device in response to a determination of the presence of the event signal.
