Chapter 19: Paper Feed Motor Assembly
This is the fifth of six related chapters which deal with the base/feed mechanism. In this
chapter you will remove and replace the paper feed motor assembly.
To remove and disassemble the paper feed motor assembly the base/feed mechanism
must be separated from the printer. If this has not been done see chapter 15.
The printer will be reassembled in chapter 20 by replacing mechanisms in the base/feed
mechanism.
