SCANNER FEATURE OF ScanMaker 3880
SCANNER TYPE : flatbed scanner offer 3 buttons function ( Scan / Copy / E-mail ).
One pass , 48Bit ( R,G,B ) color scanner with USB2.0 interface.
The following S/W driver can support ScanMaker 3880 to do photo scanning under PC Wins system.
ScanWizard 5 V6.113 or its later version ( PC version ) : PC WinXP / 2K / Me / 98 system.
OPTICAL RESOLUTION : 1200dpi (H) * 2400dpi (V)
SCAN AREA : 8.5” (W) * 11.7” (L) in Reflective mode,
CCD TYPE : 2905D ( Toshiba CCD ) , 5400 PIXELS ( 5100 EFFECTIVE PIXELS ).
TCD-2905D is a stack CCD with 6 rows of line sensors ( R1,R2, B1,B2, G1 & G2 ),
each of line sensor has 5400 pixels totally, but R1 and R2 has 0.5 pixel shift in alignment
each other ( G1and G2, B1and B2 have the same design also. ). This reason can make
scanner resolution was enhanced from 600dpi ( 600dpi * 8.5” ( W ) = 5100 effective pixels )
to 1200dpi ( R1 + R2 = 10200 effective pixels = 1200dpi * 8.5” ( W ) ).
A/D CONVERTER : Chip Scan113 (16BIT/Pixel ) on Main Board ( MARCH-0503 ).
SENSOR : HOME SENSOR *1 ( IN THE BUTTON BOARD, MARCH-BUT ).
STEPPING MOTOR : 12Vdc/0.5A ( NEOCENE 2T3542142 ), MOTOR STEP=3.75 DEGREE/STEP
MICRO STEPPING RATE = FULL, HALF
FULL STEP = 1200 dpi ( V )
HALF STEP = 2400 dpi ( V ) ( ScanMaker 3880 run at 2400dpi )
STEPPING MOTOR DRIVER : IC CHIP ( 6219 ) ON MAIN BOARD ( MARCH-0503).
LAMP TYPE : COLD CATHODE LAMP *1 IN CARRIAGE ASSEMBLY OF ScanMaker 3880
AC-INVERTER : DC INPUT VOLTAGE = 12V
LAMP START-UP AC VOLTAGE = 550VP-P ( MINIMUM )
LAMP AC CURRENT = 10mA (APPROXIMATELY)
VIDEO MEMORY BUFFER : 1M WORD ON MAIN BOARD ( MARCH-0503 ).
DATA PROCESSING CHIP : SCAN CHIP : SQ113 ON MAIN BOARD ( MARCH-0503 ).
SCANNER CONTROLLER : SCAN CHIP : SQ113 ( 8 BIT PROCESSOR ) ON MAIN BOARD.
USB INTERFACE : SCAN CHIP : SQ113 ( USB CONTROLLER ), USB 2.0 INTERFACE.
