Stacker Problems
The power stacker augments the paper feed system of the printer. The most
frequently occurring problems in the paper feed system are paper jams.
Because of the electromechanical nature of the system, other problems that
can occur are worn or poor electrical connections and cabling, worn or
defective feed motors, worn or damaged mechanical components, or
incorrect installation of the stacker assembly. Table 6 shows some of the
problems that can occur with the power stacker and the page where you can
find the troubleshooting procedure.
