Performing routine maintenance will ensure optimal image quality and
prolong the life of your scanner.
The Maintenance monitor on the Home screen of the Ngenuity
Operator Utility (NOU) provides reminders as to when scanner
maintenance is required.
Based on the intervals set, the Maintenance LED on the control panel
will also blink. To turn the Maintenance LED off and to reset the interval
count for future reminders, click on the link to the right of the expired
maintenance item after each maintenance procedure is completed.

Cleaning procedures Cleaning your scanner and performing preventative maintenance on a
regular basis is required to ensure the best possible image quality.
Some document types generate more paper dust and debris and may
require more frequent cleaning.
Before cleaning your scanner or replacing consumables, review the
following information:
• Turn the scanner off and unplug it from the wall outlet before
performing maintenance procedures.
• Remove any jewelry or any items from hands or wrists that could
become caught on internal scanner components.
• Some debris from the rubber tires on the pick and drive rollers and
separation roller is normal. Tire debris does not always mean that
the tires are worn or damaged. After cleaning, inspect the tires for
wear and replace the separation roller tires or pick and drive roller
tires if necessary.
• When cleaning rollers/tires, allow the rollers/tires to dry completely
before scanning.
• Use only the recommended cleaning supplies. Using unapproved
cleaning fluids or solvents may damage the rubber tires.
• Do not use cleaners in confined areas; use with adequate
ventilation.
• Do not use flammable compressed aerosols on or around the
scanner.
NOTE: To access the Material Safety Data Sheet (MSDS), you will
need to provide the catalog number or keyword of the
supply. See “Supplies and Consumables” later in this
chapter for catalog numbers.

Cleaning the feed rollers Feed rollers include the pick roller, drive roller and separation roller.
All feed rollers should be cleaned and/or replaced at the same time to
ensure optimal scanner function. Maintenance reminder intervals (both
cleaning and replacing) are based on all feed rollers having the same
life cycle.
Cleaning the pick and drive rollers
When the feed rollers become dirty, they may begin to slip on paper or
cause multifeeds. To prevent feeding problems and avoid rubber tire
replacements, it is recommended that you clean the tires on the rollers
every 10,000 pages or as needed. Different document types, the
condition of the documents being scanned, and the volume of scanning
may require more frequent cleanings.
Always remove the rollers from the scanner before cleaning to ensure
best results.
1. Turn off the scanner and unplug it from the wall outlet.
2. Open the scanner cover.
3. Remove the pick roller by rotating the release lever up, push the
pick roller to the right and remove it.
NOTE: Before cleaning the pick and drive rollers, inspect the tires.
If the tires show signs of wear or damage, replace them.
See “Replacement procedures” later in this chapter.
4. Using a roller cleaning pad, scrub the roller tires using a side-to-side
motion. Rotate the roller to clean the entire surface.
IMPORTANT: The roller cleaning pad contains sodium lauryl ether
sulfate and sodium silicate which can cause eye
irritation. Wash hands after use. Refer to the MSDS
for more information.

5. Re-install the pick roller.
6. Remove the drive roller by pushing the roller to the right. Hold the
drive roller shaft in place and slide it off the shaft. Gently release the
drive roller shaft back into position.
7. Using a roller cleaning pad, scrub the roller tires using a side-to-side
motion. Rotate the roller to clean the entire surface.
8. Re-install the drive roller.
Cleaning the separation roller
9. Pull the separation roller door forward and remove the separation
roller.
NOTE: The separation roller cover is spring-loaded. Hold the
separation roller cover back until you remove the
separation roller, then gently lower the roller cover back in
place.
10.Using a roller cleaning pad, scrub the roller tires using a side-to-side
motion. Rotate the roller to clean the entire surface.
11.Re-install the separation roller by aligning the slots on the
separation roller with the holders.

12. Close the scanner cover and reset the maintenance reminder by
clicking on the Clean Feed Rollers link on the Maintenance
monitor.
13. Click Yes on the dialog box to confirm the feed rollers have been
cleaned. The reminder will be reset for the next required
maintenance session.

Cleaning the optics Optics include the imaging guides, camera glass covers and
sensors. All of the optics components should be cleaned at the same
time.
NOTE: The lamps are not part of the optics. The lamps (LEDs) should
not be cleaned with wipes or solvents.
Cleaning the imaging guides and camera glass covers
To prevent streaks in images, reduced OCR/ICR/Barcode recognition
rates, blurred images, etc., you should clean the imaging guides every
50,000 pages.
The two imaging guides which are inside black, plastic frames are
located in the top and bottom transport trays. When removing an
imaging guide for cleaning or replacement, the entire assembly
(imaging guide and frame) are removed and replaced as one piece.
Clean the camera glass covers at the same time you clean the imaging
guides.
CAUTION: Do not remove the imaging guide from the black frame.
1. Open the scanner cover.
2. Gently pull the 2 fastening clips that secure the top imaging guide
towards the front of the scanner to release and remove the imaging
guide from the transport.
3. Using a Staticide wipe, clean both sides of the imaging guide. Be
careful not to touch the cleaned glass.
IMPORTANT:Staticide wipes contain isopropanol which can cause
eye irritation and dry skin. Wash your hands with soap
and water after performing maintenance procedures.
Refer to the Material Data Safety Sheet (MSDS) for
more information. The MSDS is available on the
Kodak web site at www.kodak.com/go/MSDS.

4. With the imaging guide still out of the scanner, locate the glass
camera cover between and below the LED lamps.
5. Using a clean dry swab, gently wipe across the glass camera cover
to remove any dirt and dust particles. Do not spray any solvent on
the swab unless a dry swab will not remove the residue on the
glass. If you need to use solvent, spray the solvent on the swab. Do
not spray solvent in or around the internal components of the
scanner.
6. When the camera cover is clean, re-insert the cleaned imaging
guide into the scanner by holding the frame of the imaging guide so
that the fastening clips are on the back side of the imaging guide.
Slide the guides under the transport tray towards the feeder table
and ease the back side of the imaging guide into position.
7. Repeat Steps 2 - 6 to clean the bottom imaging guide and bottom
camera cover.
8. When finished, close the scanner cover.

Cleaning the sensors
There are 7 sensors that require regular cleaning. Use only the
supplied blower brush to clean these sensors. Do not use any type of
cotton swab or cloth as these items may leave lint in the sensors.
9. Feeder sensor: Place the brush end of the blower brush into the
feeder sensor area and squeeze the blower brush several times to
clean the feeder sensor.
10. Gap sensor, page entry sensors and pass thru sensor: Open
the scanner cover to clean these 5 sensors by placing the brush
end of the blower brush into the each sensor area and squeeze the
blower brush several times to clean.
