Cleaning the Scanner

In order to maintain the scanned image quality and prevent dust accumulation, it is recommended that you clean the scanner (outer casing and image sensor inside the scanner) approximately every

50-100 scans, or if vertical lines or stripes appear on the scanned image. Use only the recommended and supplied tools to clean the scanner.

WARNING: Do not use any solvents or corrosive liquid (i.e., alcohol, kerosene, etc.) to clean any part of the scanner. Otherwise the plastic material will be permanently damaged.

Cleaning the Outer Casing

Please follow the instructions below to clean the outer casing of the scanner when necessary.

1. Use a suitable dust blower to blow off the dust on the scanner.

2. Use a slightly dampened cloth to wipe off any smear on the surface of the scanner.

3. Wipe the scanner with a dry and clean lint-free cloth.

Cleaning the Image Sensor

 1. Clean the scanner’s outer casing first.

2. With the scanner power off and disconnected from the computer, insert the sensor cleaning swab into one end of the output slot.

NOTE: Make sure that there is no visible dust on the swab before inserting it into the output slot.

3. Gently slide the sensor cleaning swab back and forth from one end of the output slot to the other five or six times consecutively.

NOTE: Do not apply too much force on the swab.

4. Remove the sensor cleaning swab from the slot, and store it in a safe place and protect it from dust.

Calibrating the Scanner

If the scanned image looks fuzzy or there are strange stripes on it, the scanner may need calibrating in order for the sensor to resume its original precision. To calibrate the scanner:

1. Follow the instructions beginning on page 18 to clean the image sensor, and then follow the instructions in Preparation and Initial Setup on page 10 to prepare the scanner for scanning.

2. Insert the calibration card as shown.

3. The scanner will scan the pattern on the calibration card and perform calibration to the sensor inside automatically.

NOTE: Make sure that the calibration card is inserted in the correct direction and aligned with the left side of the feeding slot. Otherwise the calibration won’t work.

Storing the Scanner

If the scanner will not be used for a prolonged period of time, follow the instructions below to store the scanner for future use.

1. Disconnect the scanner from power supply.

2. Place the scanner and power adapter in a box or bag to keep them from accumulating dust.

3. Place it in a cool and dry place where inaccessible to small children. To avoid warping the top housing, do not place heavy objects on top of the scanner.

4. After long-term storage, it is recommended that you clean and calibrate the scanner before use.

Battery maintenance

This scanner has a built-in Li-Polymer rechargeable battery. The capacity of the battery normally decreases each time you use it. Nevertheless, you can still follow the suggestions below to extend the battery’s lifetime as long as possible:

• Use the scanner at least once per week.

• Charge the battery regularly. Never leave the battery fully discharged for a long time.

• Keep the battery fully charged when not in use. If the scanner will not be used for several weeks, partially-discharge the   battery before storage.

• Keep the scanner and battery away from heat.

• If the scanner only works when the power adapter is connected, contact your dealer to replace the battery.

WARNING: Do not attempt to replace the battery yourself. Incorrect handling of the battery or using a wrong type of battery may cause damages to the product or result in personal injuries.
