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.
