1) Increased paper speed at the entrance of the unit
The AD50 copy speed is 50 cpm. So, the paper speed at the entrance of the unit
has been increased from the SR700 (200 mm/s → 250 mm/s). Therefore, the
transport drive motor has been changed.
2) Two grounding plates have been removed
Due to a change in the European Radiation Standard Class (EN55022) of the AD50
from class B to class A, two grounding plates are no longer necessary to install the
unit. Therefore, the installation procedure of the finisher has been changed (refer to
the attached installation procedure).

Classification:
For machines on which the Finisher is installed, if a large amount of copies is made right
after power-up, SC101 may occur. If the Entrance Guide is installed in the proper position,
this problem may be prevented. Please refer to the attached page for the installation
procedure.
Symptom
SC101 occurs.
Cause
If the Entrance Guide is not installed in the proper position, a gap may develop between
the Cover and the Main Frame through which the heat and humidity generated by the
paper may enter and lead to high temperature /high humidity around the lamp stabilizer. If
a large amount of copies is made right after the machine is turned on , the Lamp Stabilizer
will warm up very quickly and may lead to condensation. This may lead to a short circuit
and cause SC101.

Countermeasure
The edges of the Entrance Guide have been bent to strengthen this part and make it
easier to install. Please refer to SR710 MB#2 for the details regarding this modification.
ACTION
During the set-up of a Finisher manufactured after May 1997, please install the Entrance
Guide in a manner that will prevent a gap from developing between the Cover and the
Main Frame. Please refer to the attached page for this procedure.
In the event that an SC101 occurs on a Finisher manufactured before April 1997, please
replace the Entrance Guide with part number A6122333.
