Appendix E Introduction452IntroductionThe SureStak** Power Stacker is a factory-installed option for high speed cabinet model printers that mechanically directs thepaper from the print area to the paper stack. The power stacker is mounted in the rear of the cabinet and has its own operatorpanel. It is designed to work with forms from 5 to 12 inches (12.7 to 30.5 cm) long. Using longer or shorter paper can causeerror messages and unpredictable behavior of the stacker. The power stacker can handle forms from 3 to 16 inches (76 to 406mm) wide with no paper tent in the pull-out tray, and from 3 to 15.5 inches (76 to 394 mm) wide with the paper tent installed inthe pull-out tray.IMPORTANT Access to the stacker assembly is restricted while it is in the cabinet. You must remove the stacker assembly from theprinter to service it.This appendix has three sections:• How to operate the power stacker.• Removal/installation instructions for the stacker assembly and components that require the most frequent replacement.• An illustrated parts breakdown (IPB) showing how the power stacker is assembled and listing the part numbers forreplaceable parts.NOTE: Only replaceable parts have part numbers in the IPB.
