contamination of the platens. Once printing is completed, the paper is advanced and a
command sent to the cutter to cut off and present the printout. The paper then remains at the
cutter position awaiting the next printout.
When the printer runs out of paper, the entrance sensor detects the fact. The controller then
immediately stops printing and backs the paper up so it protrudes from the back of the printer.
This is to allow the operator to raise the UPM, remove the partially printed document, and
lower the UPM before loading a new roll of paper. If this were not done, it would be possible
for short pieces of paper to remain in the paper path without the operator's knowledge,
eventually causing an obstruction and a paper jam.
The presenter sensors continually monitors whether there is paper in the presenter, and can
be read via the Status function. Please see the TwinSide TS™ Emulation Command Set
Reference D 691 010 for details. This function is sometimes used in conjunction with the
host's peripherals to signal the user when a printout is not taken, or to initiate a retract
command that will draw the printout back into the printer and deposit it in a reject bin.
Additionally, the presenter entry sensor is optionally monitored while first printing after a cut.
After a cut, the printer "knows" where the end of the paper is. As printing takes place, the
printer also "knows" how many paper advance steps have been made, and approximately
when the end of the paper should reach the chute sensor. If the paper does not reach the
sensor when expected, the printer assumes that a paper jam has taken place and signals this
fact via the Status command.

2.4. Location of Controls and Connectors

Please see Figures 2 through 5 below for the location of connectors, indicators and controls
on the TwinSide TS™ series. Figure 2 shows a gear-side view of a TS-56 without presenter,
while Figure 3 shows the same printer with the upper print mechanism (UPM) in the open, or
service, position. In both images, the gears protected by a cover.
opposite, cable-side view of the printer. Figure 5 details the electrical connections to the
printer. Please note that, while P/N 0691001 comes equipped with a presenter, these figures
point out features that are common between presenter-equipped models and those without
presenter.
