Publication details measures to take to minimize E5C7 Error Codes on the Perfect Binder-
A1/ Perfect Binder-B1/ Perfect Binder-C1.

An E5C7 Error Code may occur due to undesired friction between the Weight Holder and the Front Shaft.
The friction encountered will result in the inability of the Weight Holder to slide freely on the Shaft.
This can cause the Weight Holder to seize on the Front Shaft and break. The breakage of the Weight
Holder ultimately leads to an E5C7 Error Code.
