FUNCTION
Sets platen for different thickness forms or paper.
Opened (raised) fully for loading paper.
Indicates relative thickness of forms or paper.
Used to set left margin and paper width. Left
tractor moves about one inch. Right tractor moves
full range.
Lock tractors in position.
Allows fine positioning of left print margin. Moves
paper slightly to left or right.
Sets top of form or first line to be printed. Rotate
to move paper vertically.
Provides reference for setting top of form or first
line to be printed.

CHAPTER 2
PRINCIPLES OF OPERATION
Section I. General Description
2-1. Scope
This
chapter presents the principles of operation for the P6000 Series printer. This information is
intended
specific
to provide the technician with a basic understanding of printer functional operation. F
circuits, see Appendix B. Mnemonics are defined in Appendix A.
or
2-2. Purpose
The P6000 Series printer is a computer output device. It receives data from a host computer and
provides
hard copy text or graphics. The hard copy is composed of an array of dots. In the case of
text, these dots are arranged in a matrix to produce characters.
2-3. Matrix Printing
a. The Dot Matrix
In
order to generate characters from dots, the dots must be arranged properly. The imaginary grid
on
which the dots are positioned is referred to as the matrix.
In normal six line per inch spacing there are 12 dot rows from the
top
of the next (Figures 2-1 and 2-2). Spacing of eight lines per inch has nine dot rows per charac
line, nine lines per inch has
ter
eight dot rows per character line, and spacing of ten lines per inch
top of one character line to the
has seven dot rows per character line.
Elongated
characters
can be generated by printing each row twice, except for the first and last (Fig
ure 2-3).

The
hammer bank contains a number of print hammers (44 for P6040; 66 for P6080) mounted on a
shuttle
