PREVENTING GUIDE STOPPER BREAKAGE

To communicate that the shape of the guide stopper has been changed to prevent it from breaking.
Also, to communicate field measures to take if the stopper breaks in the field.

<Symptom>
If the guide stopper breaks, there are cases where the buffer roller stops the copy paper, and a
stationary jam o ccurs.

<Cause>
The guide stopper determines the stop position of the flapper, but this stopper breaks as a result of the
repeated opening and closing operation of the flapper. If the stopper breaks, the flapper makes
contact with the buffer roller, and a load is placed on the rotation of the buffer roller. In the worst
case, the rotation of the buffer roller is halted, and a stationary jam occurs. (Fig. 1)
