7. Battery backup
•
The Vanadium battery accumulator retains memory contents such as system
data/user data. (Guarantees 200 hours storage under the room temperature of 22
deg. C, by 72 hour charging)
•
Also, the battery retains the contents of stored picture data. (Guarantees 3 hours
storage under room temperature of 22 deg. C, by 158 hour charging)

6.1.9 Input area features
1. Scanning method
1) Fast scan direction: CCD solid scanning with reduced optic method.
2) Slow scan direction: Moving Full/Half Rate Carriage
Face-up/Top-feed document moving (DADF)
2. Input parameter
1) Pixel density in fast scan direction
7296pels/308.86mm±1%(600ppi)
2) The density in slow scan direction
600pels/25.4mm(600ppi)
* When DADF is used, densities below 50% can be reduced to the setup rate by
electrically composing/decomposing between the adjoining pixels.
3) Scanning speed
• Fast scan direction: 264.5 s/line (regardless of magnification)
• Slow scan direction: magnification 130.0mm/sec
: reduce/enlarge Xmm/sec where X=130x100÷Red/Enl. Rate (%)
3. Document
1) Document size
• Platen
Maximum: A3 (297x420mm), 11"x17"
• DADF
Maximum: A3 (297x432mm), 11"x17"
2) Registration
• Registration position for Document on the Platen is at the left inside corner.
• Registration position for Document on the DADF is at the inside (inboard).
4. Document size sensing
1) At Platen mode
•
The document size (width) in the fast scan direction is scanned by the CCD
Sensor while the size (length) in the slow scan direction is scanned by the IIT
Size Detect Sensor.
•
The sensors scans the document immediately before/after closing the IIT Platen
Cover.
If the Start button is pressed with the Platen Cover open, the document will be
scanned immediately after the button is pressed. However, when the document
loaded has black edges, improper sensing or no sensing may result.
