While printing, the paper continues to advance and enters the paper cutter, where it passes
between the cutter blades and out the print chute and passes the chute/jam sensor. Once printing
is completed, the paper is advanced and a command sent to the cutter to cut off the paper. The
paper then retracts to a park position to avoid wasting the paper between the printhead and cutter.
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 printhead, remove the partially printed document, and lower
the printhead 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 chute/jam sensor located at the paper exit monitors whether there is paper in the chute. A
more detailed description of this sensor can be found in chapter 3.6.5.

Location of Controls and Connectors
The following figures below show the locations of connectors, indicators and controls on the
eXtendo® series.
Figure 2 shows a USB version of the eXtendo®
but also shows the alternative serial connector
when using a printer with RS232 serial interface.
Figure 3 shows the upper portion with details about the polarity of the power connector and
cable.
Figure 4 shows the opposite side of an eXtendo®, showing the Paper Advance Wheel and the
Paper Low and Auxillary Sensor connectors.
Please note that the Paper Pre-end/Paper Low Sensor connectors are optionally duplicated on the
wheel side of the printer to make connection convenient regardless of which side of the printer
might be near the cabinet side wall.
