Real-world situation Canon DR-X10C Scanner performance in real-world scanning scenarios 4, 5 Kodak i780 Scanner performance in real-world scenarios 4, 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
Real-world environment
(Mixed Batches/Transport/Reliability/
SurePath/Dust Detection)
A variety of real-world scanning scenarios were created and tested with documents scanned by the Kodak i780 Scanner and Canon DR-X10C Scanner. 4, 5
Count on Kodak for consistent and true performance.
