1.4.3 Components on Paper Input Side of Printer
Figure 1-3 shows the electronic controls on the paper-input (right) side of the printer:
Paper Loaded button
Paper fold switch
Power on/off switch
Important: Note the location of the power on/off switch. If a printer emergency occurs, use
this switch to turn the printer off.
If you run out of paper, reload paper and press the Paper Loaded button to start printing again.
The paper fold switch tells an optional power paper stacker how to stack the output paper. This
switch is used only with power paper stackers (see list of models in Appendix A, Specifications). If
you do not have the power paper stackers, you do not need to use this switch. See Section 3.4
Loading Paper for information about how to use this switch with an optional power paper stacker.
Figure 1-3 also shows the mechanical components on the paper-input (right) side of the printer:
Two tractor covers
Two tractor locks (adjustable self-centering paper tractors)
Paper sensor
Top-of-form sensor
The paper sensor tells the printer whether paper is loaded and when the paper runs out.
When you reload paper, the top-of-form sensor tells the printer where the top of the first page is.
The printer uses this information to start the printed image at the correct position on the paper.
