Loading paper and specialty media
Loading the 520-sheet trays
The printer has a standard 520-sheet tray (Tray 1), and it may have
one or more optional 520-sheet trays. All 520-sheet trays support
the same paper sizes and types. Paper may be loaded in the trays
in either the long-edge or short-edge orientation.
1 Grasp the handle, and pull the tray out.
2 Squeeze the width guide tabs together as shown, and move
the width guide to the correct position for the paper size being
loaded.
3 Squeeze the length guide tab inward as shown, and slide the
guide to the correct position for the paper size being loaded.
4 Flex the sheets back and forth to loosen them, and then fan
them. Do not fold or crease the paper. Straighten the edges on
a level surface.
5 Load the paper stack with the recommended print side faceup.
Load the paper in either the long-edge or short-edge
orientation as shown below:
Notes:
• Load sizes larger than A4 in the short-edge orientation.
• Paper must be loaded in the short-edge orientation to
create booklets if the optional booklet finisher is installed.
6 Make sure the paper guides are secure against the edges of
the paper.
7 Align the tray, and insert it.
Note: Use the size indicators on the bottom of the tray to help
position the guides.

8 If a different type of paper was loaded than the type previously
loaded in the tray, change the Paper Type setting for the tray
from the control panel.
Loading the 867- and 1133-sheet trays
Although the 867-sheet tray and the 1133-sheet tray are different
in appearance, they support the same paper sizes and types and
require the same process for loading paper. Use these instructions
to load paper in either tray:
1 Grasp the handle, and open the tray.
2 Squeeze the length guide tab inward as shown, and slide the
guide to the correct position for the paper size being loaded.
3 Flex the sheets back and forth to loosen them, and then fan
them. Do not fold or crease the paper. Straighten the edges on
a level surface.
4 Load the paper stack with the recommended print side faceup.
5 Make sure the paper guides are secure against the edges of
the paper.
6 Insert the tray into the printer.
7 If a different type of paper was loaded than the type previously
loaded in the tray, change the Paper Type setting for the tray
from the control panel.

4 Load the paper, and then adjust the paper guides so that they
lightly touch the edges of the paper stack.
• Load letter, A4, and transparencies with the recommended
print side facedown and the long edge of the paper
entering the printer first.
• Load A3, A5, B4, folio, legal, and statement paper with the
recommended print side facedown and the short edge of
the paper entering the printer first.
Notes:
– Adjust the additional paper guide to accommodate
SRA3 and 12 x 19 paper sizes.
– Do not exceed the maximum stack height by forcing
paper under the stack height limiter.
• Load envelopes with the flap side up.
Warning—Potential Damage: Never use envelopes
with stamps, clasps, snaps, windows, coated linings, or
self-stick adhesives. These envelopes may severely
damage the printer.
Note: Load only one size and type of paper at a time.
5 Make sure the paper is as far into the multipurpose feeder as
it will go with very gentle pushing. Paper should lie flat in the
multipurpose feeder. Make sure the paper fits loosely in the
multipurpose feeder and is not bent or wrinkled.

Printing confidential and other held jobs
Holding jobs in the printer
When sending a job to the printer, you can specify in the Print
Properties that you want the printer to hold the job in memory
until you start the job from the control panel. All print jobs that
can be initiated by the user at the printer are called held jobs.
Note: Confidential, Repeat, Reserve, and Verify print jobs may be
deleted if the printer requires extra memory to process additional
held jobs.
Job type Description
Confidential When you send a Confidential print job to
the printer, you must create a PIN in Print
Properties. The PIN must be four digits using
the numbers 0–9. The job is held in printer
memory until you enter the PIN from the
control panel and choose to print or delete
the job.
Repeat When you send a Repeat print job, the
printer prints all requested copies of the job
and stores the job in memory so you can
print additional copies later. You can print
additional copies as long as the job remains
stored in memory.
Reserve When you send a Reserve print job, the
printer does not print the job immediately.
It stores the job in memory so you can print
the job later. The job is held in memory until
you delete it from the Held Jobs menu.
Verify When you send a Verify print job, the printer
prints one copy and holds the remaining
copies in printer memory. Verify lets you
examine the first copy to see if it is
satisfactory before printing the remaining
copies. Once all copies are printed, the job is
automatically deleted from printer memory.
