Paper Feed
Trays 1 and 2 have identical paper feed components.
Figure 7
shows the paper feed compo-
nents for trays 1 and 2. When the tray is closed the nudger roll is released and rests perma-
nently on the top sheet. The force with which rests on the stack is controlled by a spring. The
nudger roll is turned by a small belt drive from the feeder roll shaft, which is driven by the ele-
vate / feed motor for the tray.
When the top sheet is fed to the feed roll, a single sheet has sufficient friction to turn the retard
roll, and continue being fed. If two sheets are fed, there will not be enough friction between the
two sheet to drive the retard roll, and therefore the lower of the two sheets is stalled in the nip
and is not fed through the feed nip.
The feed sensor detects the sheet, which is passed to the next nip, located in the 3TM vertical
transport. The sheet from tray 1 is passed to take away roll 1 with its associated sensor, TAR 1.
The sheet from tray 2 is passed to take away roll 2 with its associated sensor., TAR 2. The nips
in the 3TM vertical transport are driven by the 3TM transport motor. This motor also drives the
3TM horizontal transport.
Figure 8
shows the 3TM vertical transport.
Note that after the sheet has left the tray 1, 2 or 3 feed sensor, and before it enters take away
roll, there is a short wait period. This is to synchronize the leading edge of the sheet with the
marking operation. This is the case with all three trays in the module.
When the sheets leave the 3TM vertical transport, they enter the main vertical transport. This is
described in the Paper Path section.
