Tray linking
Tray linking enables the automatic linking feature for trays when you
use the same size and type of print material in multiple paper
sources (trays).
For example, if you have loaded two optional trays with the same
size print material and both are set to the same paper type; then
when one tray becomes empty, the printer automatically selects
print material from the other tray since the printer sees the trays as
linked.
If you use different print material in the trays, each source with a dif-
ferent print material must have the set to a unique
PAPER TYPE
value to disable the automatic linking feature (refer to the Adminis-
trator's Guide for detailed information about tray linking). For exam-
ple, if you did not make sure all trays have the same type when they
are linked, you could send a report to print and if you have letter-
head paper loaded into one tray, you could print the report on letter-
head paper.
