Hole Fill
Regular use of the “Hole Fill” function in the scanner requires daily cleaning
of the paper guide on the automatic document handler (ADH). The paper
guide is the long, dark gray, plastic strip on the underside of the ADH, has a
pattern of very thin images, and two cutouts for the rollers. The following
steps should be used to clean this part:
1. Apply “Xerox Lens and Mirror Cleaner (XPN 43P81)” to a clean, lint
free, non-abrasive cloth.
2. Lift up the ADH.
3. Identify the flat, dark gray paper guide on the right-hand, underside of
the DADH. The paper guide is a long, flat piece of ribbed plastic, 5
inches from the right-hand side of the DADH. The paper guide is
approximately 13 inches in length and 1 inch wide and pivots in the
right/left motion when touched. This part also has two “cutouts” in it with
two rollers resting in the cutouts.
4. Rub the cloth in the right-to-left motion across the paper guide, starting
at the back of the scanner, working your way to the front.
CAUTION
Be careful not to dislodge the thin belt near the roller closest to the front
of the scanner.
The system may inadvertently white-fill small “blocks” (~3-5 mm in size) of
a scanned image in areas of the original that are similar to the pattern on
the document feeder paper guide. To eliminate these white-fill blocks,
disable the “Hole Fill” option.

“Hole Fill” when
“Reprocessing”
The “Reprocess” command does not eliminate holes.
images in “Preview” If a “Preview” of an image is made with “Hole Fill” turned off, and
“Reprocess” is selected with “Hole Fill” off or on, the holes will not be
removed from the previewed image. Holes will be removed from the final
scan “Accept”.

Scanning
photographs
Scanning photographs through the document handler is not recommended
due to the potential for damaging the original, as well as the susceptibility of
“streaks” in the resultant scanned image.
Artifacts in
“Automatic” mode
Windows < 0.5” x 0.5” are categorized as “background” and subsequently,
are processed differently from nearby windows (documents with a lot of
“small sized” content, such as maps with “landmarks” on them, are most
susceptible to this type of failure). This also occurs when scanning originals
with light shades of yellow and blue.
NOTE: If this problem occurs, the document should be scanned in a
different orientation, or off of the platen glass.

Hints/Tips

Fast Preview
It is recommended that you leave the PC monitor screen resolution at the
default setting when the system is installed (1024 x 768). If the screen
resolution is changed from this default, the rulers on the scanner preview
window may be covered by the preview image, particularly with smaller,
custom sized originals.

More - Pictorial
Rendering
The Brightness, Contrast, and Advanced Image Adjustment controls will
not function if the “Pictorial Rendering” selection (found in the “More” button
on the “Image Quality” tab) is changed to “Threshold” for any “Original
Type” other than “Text and Line Art.”
Background
Suppression
Background suppression has improved significantly as compared to the
“DocuImage 620S Scanner” and the “Production Scanner”. Specifically, the
“Normal” selection will remove the background on the wider range of
background darkness levels. Documents with darker backgrounds or
darker colored stocks that previously required background suppression
settings of “Strong” or “Very Strong” may no longer require these settings.

SCSI scanner
connection
It is important to ensure the connectors on the SCSI interface cable that
connects the scanner to the PC is properly seated and the thumbscrews
holding the connector are tightened. If the screws on the connector are not
tightened, the connections, particularly on the scanner, may become loose
over time, resulting in one of the following fault codes: 62-125, 62-145.
System calibration
The scanner image quality may vary slightly for the first 20 - 30 minutes of
operation if the scanner has been turned off for an extended period of time.
If the scanner has been turned “off” for longer than 48 hours, it is
recommended that you calibrate the scanner immediately prior to scanning
a job for the first 20 - 30 minutes of operation after powering on.
10 Windows “Found
New Hardware”
message
Upon a reboot of the scanner and the PC, Windows may occasionally
display a “Found New Hardware” message, despite having completed a full
installation of the scanner hardware. Assuming the devices were rebooted
in the proper sequence (scanner first, until the “Ready” light is lit, then the
PC), this message can be ignored by selecting “Cancel” from the “Found
New Hardware” dialog.
11 Pictorial rendering
warning message
Changes made to the “Pictorial rendering” selection, followed by a change
in the “Original Type” selection, may yield a warning, noting that the
pictorial rendering has been automatically changed (“Warning - setting
change - the following setting will be reset: Pictorial rendering”).
NOTE: The “Pictorial rendering” selection is located by selecting the
“More” button on the “Image Quality” tab of the scanner driver.
12 Printing Help
If you attempt to print the full contents of “Help” (Go to Help and choose the
heading “Solving Problems”, then choose to print “selected heading and all
subtopics”), the last subtopic entitled “Clearing Jams and Misfeeds” does
not print and must be printed separately.

Hints/Tips
13 Low resolution
scanning of text
Scanning text printed in 10pt font or less at resolutions of 100 dpi or less
will result in image content that may be difficult to discern. These low-
resolution selections are typically used for generating thumbnails. If better
readability is desired, resolutions of 200 dpi of higher should be used.
14 Original Types /
Image File Sizes
Originals scanned using incorrect “Original Type” selection (scanning a
halftone in “Photograph” mode, for example) can yield image file sizes that
are significantly larger than the resultant file size scanned in the correct
“Original type”.
15 Second-side show-
through when
Originals with a large amount of dark content on the reverse side of a page,
may exhibit more “show-through” in the resulting scanned image than if
scanned through the document feeder. If show-through is a problem, place
a black piece of paper on top of the original being scanned from the platen.
A stronger “background suppression” setting may also help in removing
unwanted show-through.

platen
16 Scanner Support
Unpredictable behavior can result if the scanner diagnostic software
(“Scanner Support” application) is invoked while the scanner is booting.
The application should be run with the scanner fully powered off, or fully
powered on.
17 Image registration
18 “Help”
If scanned images repeatedly contain thin, black lines on the edge of the
image, run the “Setup Registration” routine in the “Scanner Support”
application to re-set the scanner’s registration.
The following information in “Help” about “Scan Tickets” is incorrect:
1. Within the Twain GUI, go to the Help menu and then the Index —>
Scan Tickets.
2. Choose the “Backing up your scan ticket tiles” option.
3. Part 2 reads: Select [Start: Programs: Windows Explorer] - with
Windows XP, it should read [Start: Programs: Accessories: Window
Explorer].
4. Part 3 reads: “Browse to C:\winnt\Twain_32\Xerox665s\international” -
with Windows XP, it should read “C:\Program Files\Common
Files\Xerox\Scanner”.
The following information in “Help” on “Scanner Specifications” is incorrect:
1. Within the Twain GUI go to Help --> Index --> Scanner Quick
Reference --> Document Feeder --> Scanner Specifications.
2. Note that under the Minimum paper dimensions reads 6.5 x 5.5 inches,
long edge feed — this should read short edge feed.
3. Under document Feeder --> Color Spaces & resolutions supported
Binary B/W reads 76 - 1200 dpi — should read 72, 75, 96, 100, 120,
150, 200, 240, 300, 400, 600, 1200 dpi.
19 Electronic Page
Deskew
Although the “Electronic Page Deskew” (Options: Preferences) is enabled
when scanning from the platen or the feeder, it is only functional when
scanning from the feeder.

DocuTech Original Types
“DocuTech” Original Type are no longer available with the
FreeFlow Scanner 665. DocuTech original types are image
quality selections that would optimize the scanner performance
such that it produced image quality similar to that which is
settings on the FreeFlow Scanner 665 that can produce image
quality similar to what is available on the original DocuTech 135.
For each desired DocuTech mode be sure to select “Xerox
DocuTech 6135” as the target printer (“Optimize image for”).
