Stapling
#
IMPORTANT
During stapling, the output trays move downward as the stack of paper that is
output increases in quantity and thickness. Once an output tray has reached its
stacking limit, or after 100 sets of prints have been output, printing and stapling
stop temporarily. Remove all of the stapled prints from the output tray, and
printing and stapling resume.
You can corner and double staple A3, B4, A4, A4R, and B5 paper.
You can corner and double staple 11" x 17", LGL, LTR, LTRR and EXEC paper.
You cannot staple vellums, transparencies, or labels.
Do not pull copies or prints out of the output area while they are being stapled.
Remove the copies or prints after they are output to one of the output trays.
