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.

A-61662 October 2011 6-5

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.

A-61662 October 2011 6-7

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.

Fastening clips (2)

6-8 A-61662 October2011

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.
