● Stop Registration Control
It is a control to stop paper at the registration position, align paper and image on the ITB at a
specified timing, and then resume paper feed.
Stop registration control stops the Pre-registration Roller. Paper fed by the Pre-registration
Roller after being picked up from the cassette or Multi-purpose Tray generates an arch due
to being pushed against the Registration Roller which has been stopped. This control stops
paper while an arch is still generated to align paper and image on ITB at a specified timing,
aligns paper and image on the ITB at a specified timing, and then resumes paper feed.

● Size Mismatch Detection Control
Whether the size is mismatched is determined by paper length.
The time a paper passes through the Pre-Registration Sensor (PS04) is converted into
distance. The converted distance and the paper size (specified by the user in case of
the Multi-purpose Tray Pickup Tray) detected by the Cassette Size Detection Switch are
compared, and if there is a difference of 20 mm or more between the two, it is judged that the
size is mismatched.
In this case, paper is not delivered, but stopped instead with a jam detected. (Jam code:
0D91)

■ Delivery Assembly
● Delivery Control
This machine executes face-down delivery (delivers paper to the machine's Delivery Tray with
printed surface down).
When face-up delivery (delivering paper to the Delivery Tray with printed surface up) is
specified in a job, image is created on the front side of the paper, and then the paper is
passed through the duplex path and delivered with no image created on the back.
● Delivery Full Detection
If the Delivery Paper Full Sensor (PS14) is ON for a specified period of time, it is notified to
the Main Controller PCB.
After notification, printing stops.
