Competitive knockouts
Testing observations and conclusions
The use of landscape format and the need for basic
imaging features are part of daily jobs.
Enabling even basic features seriously impacts
productivity of the Canon DR-X10C Scanner.
The Canon DR-X10C Scanner’s speed with the
additional VRS capability and cost drops by as much as
34% (128 ppm claim to 84.6 ppm actual) in a scenario
where the following image processing features are
enabled: 200 dpi, bitonal, duplex, auto thresholding,
auto orientation, multifeed detection, multipage
TIFF format (Test 1).
• When scanning at 300 dpi with all the other features
the same, Canon DR-X10C Scanner productivity
drops to 39.8 ppm (Test 2).
The use of basic image processing features severely
impacts the productivity of the Canon Scanner.
The Kodak i780 Scanner outperforms the Canon
DR-X10C Scanner with more imaging features
enabled, and at higher (300 dpi) resolution.
Canon markets productivity but in real-world
scenarios they run much slower. And despite a
customer’s additional investment in VRS, turning on
features continues to have a detrimental effect on
throughput speed (see charts 2 and 3 in appendices).
Key takeaways:
The Kodak i780 Scanner delivers speed, throughput
and productivity as rated, even with multiple imaging
features enabled, while the Canon DR-X10C Scanner
suffers severely compromised throughput that is far below
claimed speeds and volumes, with only the most basic
imaging features enabled.
Canon’s marketing materials promote optimal
speed and throughput levels but do not take into
account real-world scenarios, so claimed speeds
are not reflective of actual performance.
In the world of production scanning, it is the actual
features-enabled ppm results that truly count.

Throughput tests
The intent of these tests was to determine the throughput of each scanner using typical scanner
configurations. All scanners were configured with similar settings and all tests were conducted
with EMC QuickScan Pro v6.5.1 and run on the same PC host. EMC QuickScan Pro was chosen
because of its popularity as a third party application. The EMC QuickScan Pro demonstration
version was used so it would be easier for interested parties to validate results. (See Reference
A for configuration details.) The operator prepared documents prior to testing and fed them into
each scanner as quickly as possible. Five new sets of documents were used for each scanner
during testing. Each test was run for one hour with the total number of pages recorded.

Testing observations and conclusions
Competitive knockouts
Lower-quality characters pose a serious challenge for the Canon
Scanner, requiring time consuming trial-and-error brightness/
contrast adjustments that reduce productivity.
Key takeaways:
The Kodak i780 Scanner provides outstanding image and data
integrity and OCR read rates, even for real-world imaging challenges,
while the Canon DR-X10C Scanner does not perform nearly as well.
The Kodak i780 Scanner exceeds the performance of the Canon
Scanner with default settings—even with brightness/contrast
optimally adjusted for the Canon Scanner, the Kodak Scanner
outperforms it at default settings.
The Kodak Scanner, with default settings, maximizes the
integrity of every document scanned, both for viewing and
downstream data extraction in real-world scenarios.
Perfect Page image processing automatically delivers
consistently high OCR read rates, exceptional image quality, and
a greatly reduced need for rescans.
Even challenging documents become productive images
with the Kodak i780 Scanner while the Canon DR-X10C
Scanner requires a great deal of time to optimize brightness/
contrast adjustments and effort to rescan documents.
Kodak helps ensure that scanned images comprise the
best image quality possible—a critical factor in document
management workflow—while the Canon Scanner can only
make a claim to pleasant aesthetics. Kodak delivers real-world
scanner performance.
Kodak i780 Scanner
Even with optimized settings, Canon DR-X10C Scanner delivers
substandard OCR performance for a production scanner.
Without adjustments and optimized settings, the Canon
DR-X10C Scanner performance drops even further.

Kodak i780 Scanner
Vendor’s marketing claim
Contact Image Sensor (CIS): “Robust design, outstanding
imaging quality.”
Charge Coupled Device (CCD): “Superior durability and image quality.”
Sensor technology
compare/contrast
CIS array requires that documents come into direct contact
with sensor glass during imaging; this is necessary for the
sensor to capture a quality image.
CCD sensors obtain a quality image without contact between document
and sensor glass.
Sensor placement in

The elegance of Kodak’s CCD sensor design means it is not placed in the
paper path and does not come into contact with documents as they are
Real-world scanning jobs, where documents introduce dust, dirt

is directly exposed to documents during scanning.
Additionally, foam guards seal the imaging guide and surround the
mirrors, further preventing contamination.
Impact of sensor technology
on productivity, incidence of
service calls
Direct contact between sensor glass and document originals
increases likelihood of sensor glass damage. With the Canon
DR-X10C Scanner, a service call is needed in order to replace
damaged sensor glass. Uptime and productivity are jeopardized
by Canon’s technological choices.
Kodak i780 Scanner
No contact is required between a document to be scanned and CCD
sensor glass during scanning process, minimizing any chance of risk
to sensor glass surface from staples, dust or dirt on documents. CCD
sensor is located far below paper path and is additionally protected
by a glass barrier known as an “imaging guide” in Kodak i780 Scanner
specifications. Replacement of glass imaging guide, if ever required, can
be completed by end user. Kodak’s intelligent design elements enable
maximum uptime and productivity for customers.

Competitive BenChmarking
Kodak’s CCD (Charge Coupled Device) sensor provides enhanced durability over Canon’s CIS (Contact Image Sensor) technology, which requires any document being
scanned to be in direct physical contact with the sensor glass. As a result, sensor damage is a possibility. CCD sensors do not require contact and produce high-quality
images without close proximity, eliminating the possibility of sensor glass damage due to contact. The Kodak i780 Scanner is designed to maximize uptime, reduce
service calls and optimize productivity for your operation.
Conclusions
Competitive knockouts
The Canon Scanner, because of its Contact Image Sensor, requires documents
to come into physical contact with the sensor glass, creating a range of potential
problems when working with real-world documents. Some of these problems
require a service call.
Key takeaways:
The Kodak i780 Scanner is not at risk of sensor damage due to physical contact with
documents during scanning, eliminating the possibility of sensor glass damage due to
contact. The Kodak i780 Scanner, using CCD technology, is designed to maximize uptime,
reduce service calls and optimize productivity for your operation. The technology of the
Canon DR-X10C Scanner may be vulnerable to damage, and since sensor glass replacement
on the Canon Scanner requires a service call, there is a potential negative impact to uptime
and productivity.
Glass imaging guides and strategically placed mirrors that are part of the CCD
design, effectively protect the CCD from the paper path and contaminants
introduced from documents scanned. Replacement of the glass imaging
guides, if ever required, can be completed by the end user, optimizing uptime
and productivity.
In a real-world environment, busy scanning operations understand that scanners
that can’t elegantly manage the occasional stapled document without interrupting
their operation and seriously impacting their productivity, cannot provide the real
“robustness” needed in actual work environments.
The Kodak i780 Scanner handles occasional staples and common dust
without maintenance of special parts, in order to maximize uptime in busy
production environments.
The Kodak i780 Scanner’s sensor and scanner design easily tackles common realworld work environment hazards in a busy production scanning environment.
The Canon DR-X10C Scanner utilizes sensor technology that may be vulnerable to
damage, and therefore puts customer productivity at risk.
The Kodak i780 Scanner’s sensor design, including CCD technology, sensor
placement far below the paper path, protective foam barriers that protect the sensor
from staples and other contaminants introduced on scanned documents, and
customer-replaceable imaging guides, all combine to optimize image quality and
productivity in real-world customer operations.
Kodak’s sensor technology is superior in durability to that used by Canon. For robust
imaging capabilities, turn to the brand you trust—Kodak—for technology you can
count on.

Misfeed management
Kodak i780 Scanner
Kodak i780 Scanner vs. Canon DR-X10C Scanner
Canon DR-X10C Scanner
Side-by-side testing shows that with a challenge set of 50 documents, fed five times as consecutive batches, Canon’s misfeed detection/retry mechanism and required operator
intervention—at both the Operator Control Panel and the Host—result in throughput deficits. Overall productivity of the Canon Scanner with this challenge document set is
exceeded by the Kodak i780 Scanner’s performance with the same set of challenge documents.3 The lack of flexible options for the operator to effectively manage misfeeds,
based on both attributes and workflow priorities, contributes to both a “clunky” workflow for the operator to manage, and hampered throughput (when Canon’s misfeed
detection/“retry feeding” mechanism is enabled).
“‘Double-Feed Re-try mechanism’ allows
the Canon DR-X10C Scanner to re-feed
any document that appears to its sensors
as a double feed”
Canon DR-X10C Scanner Performance3
Kodak i780 Scanner Performance3
When “retry feeding” is enabled, the Canon Scanner experiences
throughput deficits as the operator is forced to interact with both the
operator control panel on the scanner and the host, to observe and
compare the image held in the output tray and displayed for action on
the host.
Common documents can be mistakenly detected by the Canon Scanner
as double-feeds, based on the technology utilized, including common
applications such as checks or EKG printouts taped to letter-size paper
within a batch.
“User-adjustable ultrasonic double-feed
detection sensors”
“Rapid Recovery System for superior,
reliable and flexible document handling”
Any document overlap detected by sensors (documents with lead edges
offset by less than 3.5 inches) trips the Canon DR-X10C Scanner’s retry
mechanism, resulting in documents being backed out of transport and
auto-fed again (retried). Operators can choose a setting of one, two, or
three “retries.”
If the set number of retries fail (the document continues to be seen as a
misfeed), a message appears on the OCP: “ignore” or “retry.” Message
must be cleared by the operator before the job will continue. The misfed
document will be held in the output tray, but resolving the image to be
saved or deleted and rescanned at the host, must be done after inspection
of the output tray, the paper path, and the image at the host. An action to
delete or save each image noted as a misfeed also must be taken by the
operator before the job continues.
These multiple operator steps, coupled with the slowdown caused by
the misfeed retries, result in reduced productivity for the operator and
diminished throughput for the operation.
3-D ultrasonic sensors reliably detect true double feeds and are aligned
with the transport to help ensure documents are imaged and saved to
the host. Operators resolve each incidence at the host by inspecting
the last scanned image and/or rescanning the misfed original. Options
exist in the Kodak i780 Scanner’s misfeed detection feature settings,
enabling the operator to optimize productivity, operator control,
or throughput.
Operators can manage misfeed detection workflow in three ways:
Option 1: Optimized operator control: “beep and stop”—alerts operator
with an audible beep, stops job and application, leaving detected
document in output tray at top of stack for retrieval while saving
the image to host. Operator inspects output tray and image at host.
Clicks at host to resume application and pushes button at scanner to
restart job.
Option 2: Optimized operator productivity: “beep and pause”—alerts
operator with an audible beep at the scanner and does NOT require
host interaction to continue the job. The triggering document is always
imaged and saved, so operator has option to review scanned image to
determine if intervention is really needed, or to continue job.
Option 3: Optimized throughput: “beep and continue”—alerts operator
that a misfeed is detected but scanning continues. Image is saved and
passed to host for later operator inspection to determine if misfeed was
detected in error (such as when mixed batches turn up a previously
undetected envelope).
In side-by-side testing with a challenge document set, as well as with
intentionally induced double feeds into a document set, the Kodak i780
Scanner’s throughput performance and productivity exceeded that of
the Canon Scanner by as much as 50%.3 These results demonstrate
that the elegant and flexible misfeed management capabilities in
the Kodak i780 Scanner design and architecture, outperform those
from Canon.

Canon Marketing Claims
Testing observations and conclusions
Competitive knockouts
The Canon DR-X10C Scanner does not offer flexible options for the operator to
manage misfeeds in the most time-efficient manner.
Key takeaways:
The Kodak i780 Scanner delivers far greater flexibility, customization and practical
real-world choices in terms of misfeed handling and management for optimum
productivity. The Canon DR-X10C Scanner’s options for handling misfeeds may at first
seem creative and appear impressive in a simple demo, but side-by-side testing shows
that with a real-world set of documents, productivity is significantly compromised by
Canon’s “retry feeding” feature. This feature takes time to stop the transport, reverse the
document back on the input stack, and repick the document from the stack. The retry
feeding feature may actually lead to the loss of data in misclassified true multifeeds, due
to over-reliance on this feature by operators.
The Kodak i780 Scanner provides far more elegant and flexible misfeed
detection and control, allowing the operator a choice to prioritize throughput,
control or productivity, based on batch attributes, job and document
characteristics, and workflow needs.
Canon offers users limited options for enhanced productivity while managing
misfed documents.
In the real world of production scanning, a choice is often made to flag a misfeed
and continue scanning to maximize throughput and efficiency (as possible with
the Kodak i780 Scanner). The Canon model does not offer this possibility.
Canon makes no accommodation for real-world documents that are common
in certain industries, such as EKGs or checks taped to a letter-sized document.
These real-world documents are falsely detected as misfeeds by the Canon
Scanner, slowing down operations; while the Kodak i780 Scanner will effectively
image and pass these critical documents through as needed, efficiently and with
integrity, providing you with the imaging performance you’ve come to expect
from a trusted vendor like Kodak.

of documents.
Appendices
Appendix 3—Part A—Misfeed management—Testing methodology and results
Kodak’s Quality Assurance Team conducted a series of comprehensive, competitive benchmark tests comparing the Kodak i780 Scanner/ISIS to the Canon DR-X10C Scanner ISIS/
Canon DR-X10C Scanner with VRS.
Misfeed management—test results
Challenging document productivity test
Multifeed productivity test
This test was intended to simulate a very challenging document including a wide range of sizes,
thicknesses and finishes.
This test is intended to simulate a job set with pages that create real multifeeds where
two pages feed at the same time through the scanner and cannot be separated with
retry feeding.
General test steps:
• Operator scanned five prepared challenge stacks.
The job stream consisted of 100 pages with induced multifeeds placed every 10 pages
in the document stack starting at page 5. The document stack was used for all multifeed
tests described.
• The stacks were loaded separately, one following another.
Scanner features and settings profile used for multifeed productivity test:
• Images of real multifeeds were not included in the batch.
300 dpi bitonal, duplex, auto orientation ON, auto thresholding ON, multifeed detection ON,
all zones ON, set to disable scanner on multifeed detect. Multipage TIFF output selected.
Canon “retry” count set to one attempt.
Scanner features and settings profile for challenge document productivity test:
General test steps:
• Each real multifeed was rescanned.
200 dpi bitonal, duplex, auto orientation ON, auto thresholding ON, multifeed detection ON,
multifeed retry ON, all zones ON, set to disable scanner on multifeed. Multipage TIFF output.
Canon “retry” count set to one attempt.
• Operator scanned five prepared 100-page multifeed stacks.
• The stacks were loaded separately, one following another.
• E
ach multifeed page was rescanned as quickly as possible by removing the sticky
note and placing the document back in the feeder.
• W
hen the images of the multifeed document were sent to the host they were removed
(deleted) from the batch before the rescan.

Kodak i780 Scanner vs. Canon DR-X10C Scanner
Kodak i780 Scanner
Canon DR-X10C Scanner
Real-world situation
Canon DR-X10C Scanner performance in real-world scanning scenarios4, 5
Kodak i780 Scanner performance in real-world scenarios4, 5
Mixed batches—variety of
document weights, sizes and
thicknesses scanned
Any real diversity of documents (checks, envelopes, etc.) throttled
scanner throughput by detecting false misfeeds, unless “misfeed retry”
feature was turned off. A wide document range initiates misfeed detect/
rapid recovery mode, requiring ongoing operator intervention and slowing
down throughput. With misfeed retry feature on, operator had to respond
constantly to scanner control panel error message, as well as resolve
physical document output vs. electronic images saved at the host.
Operator must determine if documents held in tray are only images
not captured.
SurePath paper handling delivered consistent, rated productivity
with ultrasonic double feed detection sensors enabled, and
always fed the image to the host. (A design created with the
operator’s ultimate productivity in mind.) Minimal misfeeding
and jamming during testing. Messaging at host minimized the
“clicks” necessary to clear real misfeeds and quickly restart
the job.
Torque
Canon’s active torque control is not sensitive enough for a variety of
documents, which resulted in bowing and ripping of documents when
speed setting was not adjusted properly for document
types fed.
Kodak’s separation rollers ran fast at initial contact with paper to
smoothly peel document off the top, then returned to a stable
speed—no manual intervention needed.
Standard-size documents
with checks or EKG printouts
attached with tape
Documents viewed as misfeeds, slowing scanner throughput and
requiring operator intervention and resolution at control panel
and host.
Captured images accurately with no productivity loss.
Dust and contaminants
Detected dust and attempted to clear, but streaks still appeared on
images. Confused dust with denser objects, causing scanning to stop.
Auto dust detection occurred only when scanner was first turned on, at
start of job, or coming out of energy saver mode. If dust accumulated
during a job, the scanner did not stop, clean and restart the job,
automatically. (Operator intervention and initiation of dust detection
mid-job resulted in dust being found and cleared in some instances.)
Streaks on images caused by dust accumulation were visible long before
the system auto initiated and cleared dust from the image path.5
Kodak i780 Scanner’s design focuses on keeping dust away
from optics. CCD sensors are encased in glass and additionally
protected by a glass barrier—known as an imaging guide—and
foam guards to prevent dust from accumulating. No issues with
dust forming on the plate. Blower fans pulled in clean air and
pushed out contaminants and dust (while cooling lamps).5
Count on Kodak for consistent and true performance.
Count out Canon.

Competitive knockouts
Operators of the Canon DR-X10C Scanner must be constantly vigilant when
preparing documents for scanning, completing more extensive presorting, or risk
ongoing misfeeds along with associated downtime and productivity.
Key takeaways:
The real world of scanning is not a perfect world. Mixed sizes, shapes, and weights—
along with attachments, staples, colors, folds and other common issues—occur daily.
To achieve true productivity, variables must be accounted for and handled with ease
to ensure robust performance. The Kodak i780 Scanner delivers reliable productivity
at rated speeds day after day, thanks to a combination of speed, productivity building
features, and robust paper handling. In tests, the Kodak i780 Scanner seamlessly
handled mixed document batches and avoided the types of productivity issues that
encumbered the Canon DR-X10C Scanner. The Canon Scanner arrives with a variety of
troublesome design elements that slash productivity, create headaches and hassles, and
negatively impact image quality.
The Canon DR-X10C Scanner creates potential confusion because with misfeed
retry mechanism engaged, operator must respond to scanner control panel
messaging as well as resolve any discrepancy between physical document
output and electronic images saved at the host to discover if these were the
only images “missed.” Occurrences of this scenario during testing diminished
productivity significantly.
No matter how much dust is introduced to the Canon DR-X10C Scanner during
a job, dust detection software will not be induced to stop/check/clear the dust
automatically. Only when the operator intervenes will dust be cleared at this
point. Streaking on images was visible during the running of a batch, with auto
dust removal not being activated until a new batch was initiated.
Divergent document batches befuddle the Canon DR-X10C Scanner. Envelopes,
checks and varied sizes throttle the scanner’s throughput, unless the “misfeed
retry” feature is turned off. Batches with a wide range of document types and
sizes send the Canon Scanner into misfeed detect/rapid recovery mode, which
reduced productivity in side-by-side testing.4
Canon claims exclusive paper-feeding technology that easily handles
documents of the widest range of sizes, weights and types to deliver high
productivity. However, when testing the Canon DR-X10C Scanner side-by-side
with the Kodak i780 Scanner, the Canon Scanner’s retry feeding mechanism
slows down overall throughput as it detects false double feeds when common
document types are fed. Kodak’s CCD sensors track every page, check for
overlaps and misfeeds, and help deliver outstanding image quality at full rated
speed. The Kodak i780 Scanner is not fooled by adhesive labels or varying paper
thicknesses, and requires no operator calibration to optimally handle the widest
variety of document types and thicknesses as defined in its specifications.
Dust can be a significant problem (for cleaning and image quality) with the
Canon Scanner, as a questionable design for detecting and clearing dust may
allow it to negatively impact image quality while setting false expectations for
dust-free imaging with customers. Kodak’s exceptional sensor and transport
Methodology
technologies and design effectively minimize quality issues due to dust.

Appendices
Appendix 4—Part A—Real-world environment—Testing methodology and results
Kodak’s Quality Assurance Team conducted a series of comprehensive, competitive benchmark tests comparing the Kodak i780 Scanner/ISIS to the Canon DR-X10C Scanner ISIS/
Canon DR-X10C Scanner with VRS.
Misfeed management—test results
Challenging document productivity test
Multifeed productivity test
This test was intended to simulate a very challenging document including a wide range of sizes,
thicknesses and finishes.
This test is intended to simulate a job set with pages that create real multifeeds where
two pages feed at the same time through the scanner and cannot be separated with
retry feeding.
General test steps:
• Operator scanned five prepared challenge stacks.
The job stream consisted of 100 pages with induced multifeeds placed every 10 pages
in the document stack starting at page 5. The document stack was used for all multifeed
tests described.
• The stacks were loaded separately, one following another.
Scanner features and settings profile used for multifeed productivity test:
• Images of real multifeeds were not included in the batch.
300 dpi bitonal, duplex, auto orientation ON, auto thresholding ON, multifeed detection ON,
all zones ON, set to disable scanner on multifeed detect. Multipage TIFF output selected.
Canon “retry” count set to one attempt.
Scanner features and settings profile for challenge document productivity test:
General test steps:
• Each real multifeed was rescanned.
200 dpi bitonal, duplex, auto orientation ON, auto thresholding ON, multifeed detection ON,
multifeed retry ON, all zones ON, set to disable scanner on multifeed. Multipage TIFF output.
Canon “retry” count set to one attempt.
• Operator scanned five prepared 100-page multifeed stacks.
• The stacks were loaded separately, one following another.
• E
ach multifeed page was rescanned as quickly as possible by removing the sticky
note and placing the document back in the feeder.
• W
hen the images of the multifeed document were sent to the host they were removed
(deleted) from the batch before the rescan.

Appendix 5—Real-world environment—Testing methodology and results (dust and contaminants)
Kodak’s Quality Assurance Team conducted a series of comprehensive, competitive benchmark
tests comparing the Kodak i780 Scanner with VRS to the Canon DR-X10C Scanner ISIS. Testing
parameters exceeded normal benchmark tests.
Real-world results: testing results (for dust and contaminants)
Tests performed:
1) Performance of Dust Evasion System
Test 1—Description and detailed results
The intent of this test was to seed the imaging area of the Canon DR-X10C Scanner with
a large quantity of naturally made paper dust. Dust was collected from Kodak Scanners
normally used for testing purposes in the QA Lab. Dust was placed on the upper and lower
image paths.
This is a photo of the dust that was seeded in the scanner at the beginning of the test. The
dust was collected from several scanners in the QA Lab. This was not “manufactured” dust.
Result—This test was halted when we could not get the Dust Detection System to detect
dust in the scanner during normal operation.
2) Determine the Dust Particle size needed to trigger the Canon DR-X10C Scanner Dust
Detection System
Result—This test was halted. We could not get dust to trigger the detection system.
Canon DR-X10C Scanner Streak Detection Software
Testing was performed using Dust Detect Modes ON1 and ON2.
This photo was taken after the first sheet was scanned. Notice there is little sign of the piles
of dust that had been placed in the scanner.
Note: Dust Detection occurs prior to scanning the first image.
Canon DR-X10C Scanner Sleep Mode
The scanner has a configurable sleep mode. The settings are 10, 60, and 240 min.
We did not find a way to turn this off.
When the scanner is enabled after waking up from Stand-by Mode, the cleaning
system activates.

This is a portion of the first image taken. There were streaks both in the image and in the
background.
The intent of this test was to run the scanner until there was a visible streak in the image and
disable the scanner. When the scanner was re-enabled the dust detection system was to
detect the dust, clean the imaging area and continue scanning. This test would be repeated
until the Dust Detection System could no longer correct for the dust on the guides.
To speed up the creation of dust, the Dust Creator Tool was used.

During our testing we noticed that there were very visible streaks in the images. When the
scanner was disabled and re-enabled, the Dust Detection System did not detect the dust.
Conclusion
The scanner’s ability to remove large amounts of dust from the imaging area was observed.
However, there was still a noticeable streak in the image after the dust was removed.
The dust streak grew from 1 pixel wide to about 49 pixels wide. Dust was not detected by the
Dust Detection System using either the ON1 or ON2 settings.
Conclusion
The Dust Detection System did not detect dust that was clearly visible in the image.

Test #2—Determine dust particle size to trigger DR-X10C Dust Detection System—
detailed results
he intent of this test was to determine under what conditions the Dust Detection System
T
would detect dust.
We placed a pile of dust just before the image guide and allowed the document to spread dust
throughout the scanner. The dust was visible in the image, but the Dust Detection System did
not detect a dust error.
We scanned in bitonal image capture mode and got the same results.
As a last test we taped a human hair across the imaging area. This was immediately detected
when the scanner was enabled.
Using a “Dust Creation Tool” to create dust quickly, we also needed a way to prevent the dust
brush from cleaning the imaging area. We taped a piece of plastic document protector over
the brush mechanism.
To determine if the Dust Detection System was operating, we placed a sticky note over the
image guide. This action triggered a dust detection “event.”
We then cut the sticky notes into smaller and smaller width strips and placed them on the
image guides. This also triggered a dust event. We were able to create a sliver at about 1/16th
inch wide. This also triggered a dust detection event. We concluded that the Dust Detection
System was functioning.
We scanned for several days using the Dust Creation Tool. We were disabling and re-enabling
every 10 documents. The Dust Detection System did not detect dust.
Overall testing conclusion
The Dust Detection System did not detect dust but could detect more dense or solid objects.
We concluded that if the test was run long enough, the dust would have built up to the point
were the Dust Detection System would have triggered an event. However, streaks caused by
dust would have been noticeable in images long before then.
