Page 36 3.3 Optional image function Gradation [A.4.7 SET WINDOW command / DTC mode] Gradation specifies the gamma curve correction before processing Dynamic Threshold. When scanning news papers or old documents which background is dark, it is desirable that the gamma curve has coarse steps in the lighter side and fine steps in the darker side. This is called High Contrast gamma curve.
Page 37 Image Functions Dynamic Threshold Curve [A.4.7 SET WINDOW command/DTC mode] For the Dynamic Threshold function, the threshold is changed with the average optical density of a small area (e.g. 5 x 5 pixel area). Relation between the threshold and maximum density is formed as a curve when the threshold is expressed in the Y-axis and the maximum density in the X-axis.
Page 38 3.3 Optional image function Equal to White [A.4.7 SET WINDOW command/DTC mode] Equal to White specifies the result of binaizing when the value of a pixel equals the threshold. The default is Equal to White OFF. The effect of this parameter is slight but, if the scanned image text is bold, set to Equal to White. If the scanned Image text is too narrow or lost, set to Equal to Black (Equal to White OFF).
Page 39 Image Functions Noise Removal [A.4.7 SET WINDOW command / DTC mode] Noise Removal reduces the isolated spot noise after Dynamic Threshold. If the image is noisy. Turn on the Noise Removal and set the granularity to the size of noise to be removed. The parameter of Noise Removal is as follows.
Page 40 3.3 Optional image function Smoothing [A.4.7 SET WINDOW command / DTC mode] Smoothing in DTC mode is done after binarizing.

Page 75: Scsi Bus
A.2 SCSI Bus A.2 SCSI Bus A.2.1 System configuration System configuration The SCSI bus connects up to eight SCSI devices, each linked with a daisy chain. The both ends of the daisy chain require a terminator. Each SCSI device operates as an initiator or a target, so that a series of operations are performed between a pair of initiator and target pair.
Page 76: Bus Signals
Scanner Interface A.2.2 Bus signals Initiator Signal name Type of signal Target Data Eight data-bit signals, plus a parity-bit signal that form a DATA BUS. DB(7) is the most significant bit and has the highest priority during the ARBITRATION phase. Bit number, significance, and priority decrease downward to DB(0).
Page 77: Bus Signal Drive Conditions
A.2 SCSI Bus A.2.3 Bus signal drive conditions SCSI devices drive signals of the SCSI bus. The types of SCSI devices are summarized in the following table, showing the signals that they can drive for each operating phase of the interface. There are two kinds of signal driving methods, OR tied and NON-OR tied, as shown in Table A.2.
Page 78: Bus Phases

Page 83 A.3 Bus Phases A.3.3 SELECTION phase The SELECTION phase allows an initiator to select a target for the purpose of initiating some target function (e.g., READ or WRITE command). During the SELECTION phase the I/O signal is negated so that this phase can be distinguished from the RESELECTION phase. The SCSI device that won the arbitration has both the BSY and SEL signals asserted and has delayed at least a bus clear delay plus a bus settle delay before ending the ARBITRATION phase.
Page 84 Scanner Interface A.3.4 RESELECTION phase RESELECTION is an optional phase that allows a target to reconnect to an initiator for the purpose of continuing some operation that was previously started by the initiator but was suspended by the target (i.e., the target disconnected by allowing a BUS FREE phase to occur before the operation was complete).
Page 85 A.3 Bus Phases A.3.5 INFORMATION TRANSFER phases Note: The COMMAND, DATA, STATUS, and MESSAGE phases are all grouped together as the information transfer phases because they are all used to transfer data or control information via the DATA BUS. The actual content of the information is beyond the scope of this section. The C/D, I/O, and MSG signals are used to distinguish between the different information transfer phases (see Table A.5).
Page 86 Scanner Interface INFORMATION INFORMATION TRANSFER phase TRANSFER phase bus settle delay Min. 0ns bus settle delay C/D, MSG, I/O The INFORMATION TRANSFER phases use one or more REQ/ACK handshakes to control the information transfer. Each REQ/ACK handshake allows the transfer of one byte of information. During the INFORMATION TRANSFER phases the BSY signal shall remain true and the SEL signal shall remain false.
Page 87 A.3 Bus Phases After the ACK signal is false, the target may continue the transfer by driving the DB (7-0, P) signals and asserting the REQ signal, as previously described . bus settle delay deskew delay + deskew delay cable skew delay + cable skew delay C/D, MSG Asynchronous transfer from initiator to target...
