If the encoder shaft is loosen or broken, replace the encoder shaft with a new one.
See RTB #RD074049 regarding the replacement of the encoder shaft.
Reference Information:
Check the shape of the ITB drive shaft, as there are 2 different types of ITB drive shafts
currently used for the Taurus.
If the machine is installed with the ITB drive shaft that incorporates the bossy cross
shaped ribs [A], the ITB drive shaft is the former type, which was used only in the limited
lot of the 1st mass production units. Please be noted that this former type has higher
chances to loosen the encoder shaft.
Basically, all mass production machines have the ITB drive shaft that incorporates the
bossy cross shaped ribs [A], while there is a slight possibility of some machines installed
with the former ITB drive shaft without the ribs.
