Problem Possible Solutions
Calibration has failed Make sure that:
• the lamps have been on at least 10 minutes.
• you are using the proper calibration target and it is oriented correctly.
• the imaging guides are clean (see Chapter 5, Maintenance, “Cleaning the
imaging guides”).
• the transport area is clear of obstructions.
• the sensors are clean.
• the lamp timeout is set for greater than 10 minutes.
Try calibration again. If calibration fails again, replace the lamps (see Chapter 5,
Maintenance, “Replacing the lamps”). Be sure to calibrate the scanner after
installing the new lamps. Make sure the new lamps have been on for 10 minutes
before you calibrate.
Documents are jamming Make sure that:
• the output tray and side guides are adjusted for the length of documents being
scanned.
• all jammed documents have been removed from the transport area.
• documents meet specifications for size, weight, height of batched documents,
etc.
• the sensors are clean.
• the separation roller, feed module, and pre-separation pad are clean and
properly installed.
• the transport rollers are clean.
• the imaging guides are properly installed.
Elevator tray is vibrating and
stuck in place
You may have leaned on the elevator tray or the document extenders. To recover
from this:
1. Gently push the elevator tray down as far as you can. Do not force it.
2. Disable the scanner from the host.
3. Enable the scanner from the host.
If the problem persists, cycle the power to the scanner following the controlled
power-down sequence as outlined earlier in this chapter.
Long documents are not
feeding or are jamming
Make sure that:
• the elevator tray extenders are pulled out to provide support for long
documents.
• the output tray is adjusted for the length of the documents being scanned.
• the output tray is installed properly.
There are frequent multi-feed
detection errors
Make sure that:
• the scanner has been calibrated.
• documents are larger than 2.75 inches (6.98 cm) in length.
• stickers are adhered correctly to the document.
• the access doors are completely closed.
If the problem persists, try a different sensitivity setting on the host.
