Loading Documents
To minimize wasted media due to image quality defects, properly loading the original
document is emphasized.
You may load documents to be center-justified or to align with the left justification line.
Load image side face up into the scanner. Take notice of feeding the document evenly
so both left and right sides enter simaltaneously. The scanner has a feed detection
mechanism. Insert the document quickly to ensure that it is grasped and pulled into the
scanner.

Note
Look for the No Paper Zone symbol for the left- and right-hand boundaries. Documents
loaded in these areas may become damaged and any image passing over these areas
will not scan.
Note
Also notice the left justification line. Any image in this area will be missing in the output.
Should the document skew while feeding, clean the internal scanner areas according to
the Maintenance procedure.

To Open the Scanner
1. With both hands, depress the lid latches at either end of the Scanner Lid.
2. Lift the lid up and away from you. The lid can support itself in the fully open position.
Note
Opening the Scanner Lid reveals the white, solid main roller, feed rollers, pinch rollers,
and Contact Image Sensor (CIS). Refer to the Maintenance chapter for details on
cleaning these areas.
To Close the Scanner
With both hands, grasp each side of the Scanner Lid and lower it while pushing in the
lid latches on the underside of either end. Ensure that each side clicks into the locked
position by pressing firmly on both ends of the Scanner Lid.

Product Overview

Media Exit Deflectors
The Media Exit Deflectors are designed to allow an original document to be deflected
back toward the front of the scanner as it exits the scanner, rather than downward into
the Paper Catch Basket.
Media Exit Deflectors
Insert each of the three Media Exit Deflectors into the corresponding slots along the
upper edge of the rear of the scanner. Ensure that they are inserted fully into the slots
and that they do not block the document exit opening. This is easy to overlook when
installing them.
Note
If the Media Exit Deflectors are improperly installed, document feed jams will occur, as
the document cannot exit the opening.

Maintenance
This chapter describes how to clean the scanner.
Cleaning the Machine
Do not use cleaning agents other than water and a neutral detergent on the machine
exterior. Use only a water-dampened lint-free cloth or clean, dry, lint-free cloth on the
interior scanner rollers and sensors.
Warning
To reduce the risk of electric shock, power off the machine before cleaning.
Caution
Do not use benzene, paint thinner, other volatile liquids on the machine. These substances
may discolor, deform, or crack covers.
Caution
Cleaning the machine with an excessive amount of water may cause the machine to
malfunction and/or damage documents during printing.
1. Power off the machine as directed in Powering On/Off in the Product Overview chapter.
2. Gently wipe only the exterior surfaces of the scanner with a damp, soft cloth.
Note
You may apply a small amount of neutral detergent to the damp cloth to remove
stubborn soiling on the machine exterior.
Caution
Do not use detergent on the interior parts. Doing so could cause the scanner to
malfunction. For information on cleaning the scanner parts, see Cleaning the Scanner
in this chapter.
3. Dry the cleaned surfaces with a soft, lint-free cloth.
2-1Xerox®Wide Format 7742 Scan Solution

4. After all cleaned surfaces are dry, power on the machine as directed in Powering
On/Off in the Product Overview chapter.
Cleaning the Scanner
The scanner and its components need to be cleaned on a regular basis to ensure optimal
performance.
Note
The Scanner Setup procedure (Normalization and Auto Stitch Alignment) should follow
cleaning the scanner. This is generally done by a System Administrator. Refer to the
software documentation for these procedures.

5. Wipe the Main Roller with a clean, water-dampened cloth, turning the roller as you
clean it.
6. Wipe the Contact Image Sensor with a clean, dry, lint-free cloth. If the Scanner
Contact Image Sensor (CIS) becomes dirty, image quality defects such as black lines
or streaks may appear on scanned images.
7. Wipe the Pinch Rollers and Feed Rollers with a water-dampened cloth.
8. Wipe the four Original Sensors with a dry cotton swab.

9. With both hands grasp each side of the Scanner Lid and lower it while depressing
the lid latches on the underside of either end. Ensure that each side clicks into the
locked position by pressing firmly on both ends.
10. Replace the Power Cord to restore power to the scanner.
11. Press the On/Off switch behind the scanner to turn it to the On position.
Note
Ensure the areas are fully dry before scanning.
Scanner Setup
Normalization
The Contact Image Sensor (CIS) can be sensitive to variations in room temperature. For
best results, the scanner should be normalized on a regular basis. Normalization should
be performed whenever image uniformity is visibly changing across the sensor boundaries.
This can happen when the scanner is first installed or if the scanner is exposed to a
temperature change. The scanner should also be normalized after cleaning it according
to the scanner maintenance procedure. (Refer to Cleaning the Scanner.)
For detailed normalization instructions, see the documentation for the software that
controls the scanner. Generally a System Administrator performs this task. The calibration
target that came with the scanner is used to perform normalization.

Auto Stitch Alignment
The Auto Stitch function minimizes internal stitch artifacts and is generally performed
by a System Administrator. The calibration target provided with the scanner is used to
perform this task.

Problem Solving
This chapter describes problems that may occur with the scanner and the recommended
solutions.
General Problems
This section describes problems that may occur with the scanner and the troubleshooting
procedures to solve the problems.
If the scanner does not work properly after you perform the troubleshooting
recommended in the pages below, then contact your Xerox Service Representative.
If you think a problem is occurring with the scanner, check the Status Indicator Light
and the following table.
Warning
The scanner contains precision measuring equipment and uses a high-voltage power
supply. Never open or remove scanner covers that are secured with screws unless
specifically instructed to do so, because high-voltage components can cause electric
shock. Do not attempt to alter the scanner or change the parts because it may result in
fire or smoke.

Scanner Jam Message
The Scanner Panel has a Forward Feed button and Reverse Feed button to assist with
releasing misfed documents. This is the preferred method of removing the document
from the scanner if the scanned document is not jammed (bunched up) but has simply
stopped. If the scanner stops but is not jammed and the software gives a scanner jam
message, do the following:
1. Press the Stop button on the Scanner Panel.
2. Press the Forward or Reverse button to remove the document from the scanner.
Document Jam
If the document becomes jammed in the scanner, the machine stops and an error
message displays on the screen. Clear the jammed document according to the instructions
displayed, and then reload the document.
Note
The scanner jam message remains on the screen until you clear the jam.
