“‘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”

“User-adjustable ultrasonic double-feed

detection sensors”

“Rapid Recovery System for superior,

reliable and flexible document handling”

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.
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%.

These results demonstrate

that the elegant and flexible misfeed management capabilities in

the Kodak i780 Scanner design and architecture, outperform those

from Canon.

based on both attributes and workflow priorities, contributes to both a “clunky” workflow for the operator to manage, and hampered throughput (when
