Introduction

The SureStak Power Stacker is both a factory-installed and field upgradable
option that augments the paper feed system of cabinet model printers. It is
designed to work with forms 5 to 12 inches long (12.7 to 30.5 cm) and up to
16 inches (41 cm) wide without the paper tent installed or up to 15.5 inches
(39.5 cm) wide with the paper tent installed. (See Figure 1.) Using longer or
shorter paper can cause error messages and unpredictable operation of the
stacker.
Because most of the stacker assembly is inside the cabinet, you must remove
the stacker from the printer to service it or replace most of its components.
This appendix has three parts:
•
An overview of stacker operation.
•
Removal/installation instructions for the entire power stacker assembly
and for components that require the most frequent replacement.
•
An illustrated parts breakdown (IPB) showing how the power stacker is
assembled and listing the part numbers for replaceable parts.
NOTE: Only replaceable parts have part numbers in the IPB. If you need to

Stacker Operation

The power stacker mechanically directs the paper from the printer to the
