Product Technical Overview
Launch Issue
Registration Sensor and Invert Sensor
The DADF registration sensor is installed before the registration roll. It detects that the preced-
ing sheet has left the registration roll, triggering the pre-registration of the next.
The registration sensor and the pre-registration sensor provide jam detection as the document
feeds through the document path.
The DADF invert sensor is installed immediately after the out roll. It detects the ejection of a
sheet and provides timing data for two sided jobs. Refer to Figure 7.

Feed Motor, Nudger Roll, Feed Roll and Takeaway Roll
The DADF feed motor is a stepping motor that rotates the nudger roll and feed roll in the
reverse (CCW) direction. It also rotates the takeaway roll in the normal (CW) direction. The
takeaway roll stops when this motor rotates in the reverse direction.
The feed roll and the takeaway roll are driven through clutches that are controlled by the DADF
PWB, PL 5.10 Item 11. Refer to Figure 8.
