The Xerox DocuPrint printers are certified to comply with the
performance standards of the U.S. Department of Health, Education,
and Welfare for Class 1 laser products. Class 1 laser products do not
emit hazardous radiation. The DocuPrint printers do not emit
hazardous radiation because the laser beam is completely enclosed
during all modes of customer operation.
The laser danger labels on the system are for Xerox service
representatives and are on or near panels or shields that must be
removed with a tool. DO NOT REMOVE LABELED PANELS OR
PANELS NEAR LABELS. ONLY XEROX SERVICE
REPRESENTATIVES HAVE ACCESS TO THESE PANELS.

1. 1Feeder trays
This chapter shows the steps needed to load and check feeder trays
on the DocuPrint printer, and explains what actions are necessary if
paper stock is changed.
Checking and loading feeder trays
Check the amount of paper in each feeder tray by examining the
green lights on the door of the tray. Each light represents 25 percent
of a ream, or about 125 sheets of 20 pound or 80 gsm paper.
•You do not have to interrupt a print job to load paper because
you can refill one tray while the printer is feeding from another
tray.
•The printer does not feed all the paper out of a tray. A stack of
approximately 1/4 inch / 6 mm remains in the tray.
Loading feeder trays
It is important to load paper properly in the feeder trays to prevent
jams and loss of production time. The following guidelines will help
ensure maximum efficiency of your printer operation.

Guidelines for loading paper
When you are loading the paper, follow these guidelines to prevent
paper jams:
•Remove damaged sheets.
•Load the paper with the package wrapper seam side up.
•Make sure that the direction of the curl is consistent.
•Avoid fanning the paper unless the stock is predrilled.
•Do not load the paper above the MAX line on the length guide.
•Place any paper left in the bottom of the tray on top of the new
paper stack.
•When loading predrilled paper, fan the paper and remove
loose paper plugs.
Loading the trays
Follow these steps to load a feeder tray:
1. If the Ready To Open indicator on the feeder tray door is not lit,
press the Tray Unlock button and wait for the tray to descend
and the Ready To Open indicator light before opening the tray.

2. Lift and pull on the bar along the top of the feeder tray. Slide the
tray all the way out for best access and ease of loading.
3. Press the green lever down to unlatch the paper feeder
assembly.
Caution: Attempting to move the lever in any other direction
can break it.
4. Pull out any partially fed paper from the feeder assembly and
discard it. There will be some resistance.

5. Squeeze the lever against the back of the length guide and slide
the guide toward the back of the printer.
6. Remove any paper remaining in the tray and set it aside to be
placed on top of the new paper.
7. Load paper, following the instructions at the front of the feeder
tray and carefully positioning the paper in the right-front corner
of the tray.
8. Pull the length guide forward to touch the back of the paper
stack.

9. Latch the paper feeder assembly by pressing the green dot next
to the green release lever until the assembly clicks into position.
10. Slide the tray into the printer until it latches. The tray rises
automatically into position.
11. Press the Continue button to resume printing.
Note: If you change the paper stock, you must use the Set
Tray command to reset the trays. If you change to larger paper
after an extended run of smaller paper, run 20 copies of a
sample document to clean the fusing system. Otherwise, the first
pages of the new job may be of poor quality.

2. 2Output trays
Your print jobs are sent to printer output trays, which you must
unload. You can unload each of the output trays while the system is
printing. How you do so, however, depends on the type of tray. This
chapter discusses how to check and unload the various types of trays
available.
In all cases, if the printer has stopped due to a full output tray and
does not resume automatically when the tray is emptied, press the
Continue button on the printer control console.
Checking and unloading dual stacker trays
When a stacker tray is full, the following occurs:
•The Tray Full indicator lights on the appropriate stacker tray.
•The Attention light shines steadily.
•The printer control console displays a message indicating which
output tray is full.
•The picture on the graphic display shows the location of the full
tray.
•If you select only one tray, the printer stops when that tray is full.
•If you select both trays and the first tray is not emptied by the
time the second output tray is full, the printer stops and displays
the message that both output trays are full.
Each stacker tray holds 750 sheets of 20-pound or 80gsm paper.

Unloading the dual stacker trays To unload each dual stacker tray, raise the scuffer arm and remove
the printed pages.
1 Scuffer arm
2 Tray Full indicators
Note: When both trays are full, you must empty at least one tray
before you can resume printing.

Checking and unloading the stitcher/stacker tray
An electronic counter in the stitcher/stacker keeps track of the
number of sheets printed and the number of stapled sets produced.
When a stacker tray is full, the following occurs:
•Printing stops and a message appears on the printer control
console that the output tray is full.
•The Attention light shines steadily.
The stitcher/stacker tray holds 2000 sheets (unstapled) of 20-pound
or 80 gsm paper.
Unloading the stitcher/stacker tray To unload the stitcher/stacker tray:
1. Lift the black handle on the outside of the tray.
1 Tray handle
2 Stacker arms
2. Carefully slide the tray up and out and remove the printed
pages.
Note: A false tray full condition may occur when you remove
small stapled sets without pulling the tray out. The counter is not
reset, causing the printer to stop before the tray is actually full.
3. Close the tray by sliding it back under the stacker arms.

Checking and unloading sample tray
The sample tray holds up to 100 sheets of paper from 8.5 by 11
inches / 216 by 279 mm to 8.5 by 14 inches / 216 by 356 mm. No
message appears when the sample tray is full. Because a paper jam
can occur if the tray is overfilled, empty the sample tray regularly if it
is in use.
To empty the sample tray, remove the printed pages.
Note: The sample tray can receive waste sheets purged after a
paper jam. Always clear the sample tray after clearing a jam to
prevent waste sheets from being confused with good sheets.
