4.2.3.4 PF Encoder & PF Encoder Base Removal
1. Remove Printer Mechanism. (See Section 4.2.1.4)
2. Release 4 hooks holding PF Encoder Base, then remove PF Encoder Base along
with PF Encoder from Printer Mechanism.

There are 2 types of the Rotary Scale, the Film type that has been
available since first mass production and a new Plastic type.
Needed information about details and repair are given below.
1. In the America, the Film type Rotary Scale available since first mass
production has been introduced for patent considerations. In another
development, an all new Plastic type Rotary Scales have been
introduced.
2. Concerning functioning, because the Film type and Plastic type are
completely interchangeable, PF Roller Unit and Printer Mechanism
service parts are continuing with the Film type regardless of the
developments.
3. After patent concerns are settled in America, both new products and
service parts (PF Roller Unit and Printer Mechanism) will use the
new Plastic type.
4. Points that should be considered for repair are shown below with
relationships between Rotary Scale type and PF Encoder Base type.
"Yes" means exchangeability between PF Encoder Base and Rotary
Scale. "No" means not exchangeability between these parts.
(*1): In this case, use the Long Horn Type for the PF Encoder Base.
(*2): In this case, because the horn becomes an obstacle, it is
necessary to cut off the horn. After consulting the diagram
below to confirm the correct location for cutting the horn of the
PF Encoder Base, use nippers to cut off the horn.
