NovaJet PRO 600e Service Manual
The paper sensor circuitry senses for the presence of loaded media. It
does this automatically during the start-up and load sequences. It also
constantly monitors the media during printing to determine if the
media has run out.
If no paper is sensed, the paper sensor sends this information to the
MPCB, which immediately begins an 'out of paper' subroutine. This
subroutine stops the printer from printing until more media is loaded.
The sensor also checks for the size of the media loaded so it can deter-
mine the proper printing parameters.

Keypad

The Keypad is located on the right side of the printer and consists of 8
variable-action control buttons and an LCD graphics display. The
control buttons are assigned different functions and are dependant upon
the selections that are presently shown on the graphics display. There
are four buttons on the left of the display and four buttons on the right,
with the display showing up to eight possible selections.
Figure 2-12 shows the keypad after the printer has been turned on and
finished the start up process. As seen in the figure, the control buttons
are assigned to the corresponding command that is displayed closest to
the physical location of the button.
