There are some delivery accessories available for this machine: the 2 / 3 delivery units, the finisher Z1 and the saddle finisher Y2. For the purpose of improving the
productivity, the 2 / 3 delivery units are connected to the main body as the standard equipments. Also, when mounting the finisher Y1or the saddle finisher Y2,
buffer path unit must be mounted.

In case media is delivered to the delivery outlet 1, the processing speed is accelerated when the trailing edge of media reaches the point of fixing rear 10
mm. Due to the drive configuration of the delivery motor 1, when the motor is rotating at 1/2 speed or slower, feeding speed cannot be accelerated to 1/2 speed or
faster. For this reason, the feeding speed is not accelerated when the processing speed is 1/2 speed. When the processing speed is 1/4, the feeding speed is accelerated
to 1/2 speed (71.5 mm/s). When the feeding speed of the media is accelerated to 337 mm/s and the media is delivered from the delivery outlet 1, for the purpose of
keeping consistency in its speed, the feeding speed is decelerated so that the feeding speed returns to constant speed when the trailing edge (5mm) reaches the fixing
rear roller.
When media is delivered to the delivery outlet 1 and 2, the feeding speed is accelerated at the point of inner delivery 10mm. When the processing speed is
constant, the feeding speed is accelerated to 460mm/s. Due to the drive configuration of the delivery motor 2 and 3, when the motor is rotating at 1/2 speed or slower,
feeding speed cannot be accelerated to 1/2 speed or faster. For this reason, the feeding speed is not accelerated when the processing speed is 1/2 speed. When the
processing speed is 1/4, the feeding speed is accelerated to 1/2 speed (71.5 mm/s). When the feeding speed of the media is accelerated to 460 mm/s and the media
is delivered from the delivery outlet 2, for the purpose of keeping consistency in its speed, the feeding speed is decelerated so that the feeding speed returns to
constant speed when the trailing edge (5mm) reaches the fixing rear roller.
When the media is delivered to the delivery outlet 3, the media stops temporarily after acceleration at the reversal slot, and then is fed to the delivery outlet 3 at
460mm/s. In this case as well, for the purpose of keeping consistency in its speed, the feeding speed is decelerated so that the feeding speed returns to constant speed
when the trailing edge (5mm) reaches the fixing rear roller.
In this machine, the delivery method is FD (face-down) delivery only in delivery 1 through 3. There is no so-called "reversal delivery mechanism" in which switch-
over of FU (face-up) / FD (face-down) is available.

1. Delivery to the Finisher Z1
When the machine is mounted with the finisher Z1, due to the short path length until delivery, there occurs no acceleration during delivery if the image formation
is performed at constant speed or 1/2 speed. In the case of 1/4 speed, the feeding speed is accelerated to 1/2 speed when the trailing edge of the paper passes the
point 10 mm away after inner delivery roller.
In delivery to the finisher Z1, the activation of the delivery sensor 2 is the trigger of the delivery notice to the finisher Z1.
2. Delivery to the Finisher Y1 / Saddle Finisher Y2
When the machine is mounted with the finisher Y1 / saddle finisher Y2, the buffer path unit is mounted as a standard. When feeding within the buffer path unit, the
feeding speed is accelerated to 337mm/s (when the processing speed is constant). The timings of acceleration are shown below:
