Epson 8900 Series manual Introduction, Paper-Handling System

Introduction

The Model 8900 Series Printer is one of a family of rugged, high- performance, dot-matrix impact printers, which forms letters, numbers, and other symbols by printing dot patterns. The printer offers a variety of common and unique features, such as multiple paper paths and paper-feed methods, selectable print-quality settings, zero paper tear-off to prevent waste of paper and forms, and color printing.

This chapter provides general information about the printer.

Paper-Handling System

Both models (8930 and 8920) of the Model 8900 Series Printer can print heavy-duty multipart continuous forms. In addition, the 8930 can accept hand-inserted cut-sheet paper. Upon completion of a printing operation, the printer automatically positions the tear-off perforation even with the tear-off bar to allow removal of the printed document.

A useful feature of the printer is its ability to park continuous paper out of the print station area for unloading the paper supply or for switching to another paper-handling mode. This feature lets you switch instantly from continuous paper operation to cut-sheet paper insertion (Model 8930).

Each time you load continuous paper or insert cut-sheet paper, the printer automatically positions the paper and adjusts the printhead. The Page Finder™ sensor (located on the printhead carriage) detects the top, left, and right edges of the paper and sends this information to the printer electronics. The printer uses this information to adjust the paper to the top-of-form position and to adjust the printhead to operate within the left and right boundaries of the paper, regardless of the paper width. The Z-Axis Control™ motor adjusts the printhead- to-paper (z-axis) clearance to its optimum value, regardless of the thickness of the paper or form set.
