Cleaning Materials
ATTENTION
In order to use the cleaning materials safely and correctly, read the precautions on each product thoroughly.
Do not use aerosol spray or spray that contains alcohol. Paper dust blown up by strong air from the spray
may enter inside the scanner which may cause the scanner to fail or malfunction.
Also note that sparks generated by static electricity may cause a fire.
The inside of the ADF becomes very hot when the scanner is being used. Before you start cleaning the inside
of the ADF, make sure to turn off the power, unplug the power cable and wait for at least 15 minutes for the
inside of the ADF to cool down.

For more Information about the cleaning materials, contact the distributor/dealer where you purchased this product.
Or, make an Inquiry by referring to the contact Information at the Contact for Inquiries section In Safety Precautions
bundled with this product.
Location and Frequency
The Inside of the scanner (ADF) needs to be cleaned regularly for every certain number of sheets scanned. The scanner
records the number of sheets scanned so that you can check the number of sheets scanned after you cleaned it last.
The procedure to check the number of sheets scanned is as follows.
1. On the touch screen, press -> [Cleaning & Maintenance] -> [Consumable counters].
2. On the [Consumable counters] screen, check the value for [After cleaning].
oWhen the background color of the counter is yellow
It is about time to clean the scanner.
oWhen the background color of the counter is red
It is time to clean the scanner. Clean the scanner.
ATTENTION
Cleaning cycles may vary depending on the condition of the documents. Also, cleaning must be performed more
frequently when the following types of documents are scanned:
Smooth-faced documents such as coated paper
Documents with printed text/graphics that almost cover the entire surface
Chemically-treated documents such as carbonless paper
Documents containing a large amount of calcium carbonate
Documents written in lead pencil
Documents on which the toner Is not sufficiently fused

Cleaning the Outside of the Scanner
Scanner
The scanner including the ADF paper chute (feeder) and the stacker should be cleaned with either a piece of dry
cloth, a cloth moistened with Cleaner F1/mild detergent, or a sheet of Cleaning Wipe.
Touch screen
To avoid the surface of the touch screen becoming dirty, clean it regularly by gently wiping dirt and dust off with
a soft, dry cloth.
Clean the touch screen with care. Do not rub or tap the surface with hard objects as doing so may damage the
surface.
ATTENTION
To avoid deformation and discoloration, never use paint thinner or any other organic solvents.
Be careful not to let any moisture or water inside the scanner during cleaning.
It may take a long time to dry if an excessive amount of Cleaner F1/mild detergent is used. Use only a small
amount. Wipe off the cleaner completely to leave no residue on the cleaned parts.
ATTENTION
Do not wipe the touch screen with a damp cloth.
Dust on the surface may become stuck between the touch screen and the scanner, causing the touch screen to
malfunction.

Cleaning the Inside of the Scanner (ADF) with Cleaning Paper
The Inside of the ADF can be cleaned with a sheet of Cleaning Paper moistened with Cleaner F1.
As the scanner continues to feed the documents, paper dust will accumulate Inside the ADF and it may cause scanning
errors. Cleaning should be performed approximately every 5,000 sheets scanned. Note that this guideline varies
depending on the types of documents you scan. For Instance, It may be necessary to clean the scanner more frequently
when you scan documents on which the toner is not sufficiently fused.

ATTENTION
Do not use water or mild detergent to clean the ADF.
It may take a long time to dry if an excessive amount of Cleaner F1 is used. Use only a small amount.
ATTENTION
Do not start scanning with an Image scanning application during cleaning.

7. Adjust the side guides to the width of the Cleaning Paper.
Move the side guides so that there is no space between the side guides and the Cleaning Paper.

Replacing the Consumables
This section explains how to replace the consumables for the scanner.
Consumables and Replacement Cycles
Consumables need to be replaced periodically. It is recommended that you keep a stock of new consumables and
replace them before it reaches the end of the consumable life. Also, the scanner records the number of sheets scanned
for each consumable (brake roller and pick roller), which allows you to determine when to replace the consumables.
The procedure to check the number of sheets scanned is as follows.
1. On the touch screen, press -> [Cleaning & Maintenance] -> [Consumable counters].
2. On the [Consumable counters] screen, check the [After Replacing the Brake Roller] and
[After Replacing the Pick Roller] counters.
oWhen the background color of the counter is yellow
It is about time to replace the brake roller or pick roller.
oWhen the background color of the counter is red
It is time to replace the brake roller or pick roller. Replace the brake roller or pick roller.
The inside of the ADF becomes very hot when the scanner is being used.
Before you replace the consumables, make sure to turn off the power, unplug the power cable and wait for at least
15 minutes for the inside of the ADF to cool down.

Note that the suggested replacement cycles are guidelines for using A4 (80 g/m2[20 lb.]) wood-free or wood-containing
paper, as these cycles vary depending on the type of documents scanned and how often the scanner is used and
cleaned.
