SYSTEM OVERVIEW OF THE 4635 LASER PRINTING SYSTEM
An elevator moves the tray up or down when it is in use. The
HCF trays have Paper Level switches which detect the position of
the elevator to determine the fullness of the tray. Paper Size
switches detect the size of the paper loaded in the trays.
Each processor feeder tray and HCF tray has a control panel
consisting of a button, indicators, and paper level displays.
Figure 1-7.
Feeder tray control panel
1. Ready to Open indicator. This indicator is lit when paper
can be added to the tray.
2. Please Wait indicator. This indicator shows that the tray is
in motion. It is lit when the Tray Unlock button is pressed,
when the tray is being lowered, or when the tray is being
raised. The indicator goes off when the tray elevator reaches
its destination.
3. Tray Unlock button. This button can be used any time the
Please Wait indicator is off.
•
If the tray is in use when this button is pressed, the feed
selection changes to the backup tray if one exists.
Otherwise, printing stops.
•
If the tray is in use and selected as a backup tray,
pressing this button causes the tray elevator to lower and
the tray is no longer available for auto switching.
•
If the tray elevator is in the raised position and the tray is
not in use or selected as a backup tray, pressing this
button causes the elevator to lower with no effect on
printing operations.
4. Paper Level indicators. These indicators display the
approximate quantity of paper within the tray. The display
shows paper by quarter reams up to one ream, and then by
full reams. The green indicator light appears above the Paper
Level indicator which shows the amount of paper in the tray.
