Tractors
The 2900 has two tractors to control paper movement, located on the left and
right.
A lever on each tractor keeps it locked in place on a horizontal shaft. To reposi-
tion a tractor, unlock the tractor and move it to the left or the right along the
shaft. Repositioning is generally needed only when inserting a new form or size
of paper.

Paper System Components
Print Gap
The 2900 printers offer Auto-Gap which simplifies operator set-up and printer
use by setting the optimum print gap based on the form thickness. The print
gap is automatically opened to its widest position when the printer is not
printing. To accommodate various thicknesses of paper, the print gap is
adjusted either automatically or manually. (See Chapter 2 pages 2-30 to 2-33
and Chapter 3 pages 3-56 to 3-58). If the Print Gap Detect Mode has been set to
"Auto," the auto gap sensing operation will take place the first time the power is
turned on, immediately after a "paper out" fault, when the TOF key is pressed,
and when printing is attempted without setting the Top Of Form. Dedicated
control panel keys also allow the print gap to be adjusted based on operator
preference.
Paper Tension
Vertical tension on the paper is pre-set. It is not controlled by the user.
