Use the chart below as a guide to check possible solutions to problems
you may encounter when using the Kodak i1800 Series Scanners.
Make sure that:
• the power cord is plugged securely into the receptacle in the back of
the scanner.
• the wall outlet is not defective (call a licensed electrician).
• both power switches are on (the main breaker switch on the back of the
scanner and the power switch located on the side of the scanner).
Make sure that:
• when the software was installed, it was installed by someone with
Administrator privileges.
• the FireWire cable is plugged in securely.
• the scanner shows up in the Device Manager as an "imaging" device.
• you cycle power on the scanner and PC. First cycle power to the PC.
Then make sure the FireWire cable is securely fastened, then restart
the scanner.
Make sure that:
• the power cord is plugged in and the power is on.
• the pod is completely closed.
• the scanner is enabled from the host.
• documents are making contact with the feed module.
• for documents that require special handling, press the gap release
button during feeding.
• the documents meet specifications for size, weight, etc.
• if you are feeding small documents, be sure that the documents are
covering the paper present sensor in the input elevator.
• you check the feed module, separation roller, and pre-separation pad
for signs of wear and replace these parts if necessary.
• a very dark document or curled document is not on the bottom of the
stack. Place a white sheet of paper at the bottom of the stack and scan
again.
• use Count Only mode to test feeding.
Remove all documents from the input elevator and be sure the locking
switch is in the unlocked position.
Make sure that:
• the guidelines for document preparation have been followed (e.g.,
staples, paper clips are removed; lead edges are aligned, etc.)
• documents meet specifications for size and weight.
• the multifeed sensors are clean.
• the separation roller, feed module, and pre-separation pad are clean
and properly installed.
• you have checked the feed module tires, separation roller tires and pre-
separation pad for signs of wear and replaced as needed.
• ultrasonics have been calibrated.
• the imaging guides are clean. See Chapter 5, Maintenance.
• the scanner has been calibrated. See Chapter 3, "Calibrating the
scanner".
• if using iThresholding, reduce the Contrast value.
• try a different color table.
• for color or grayscale images, consider creating a custom color table
using the Brightness and Contrast Control utility.
If unsatisfactory image quality persists, call Service.
