| IA3008-MB30A Contact image sensor heads Monochrome image sensor head (300dpi) IA3008-MB30A The IA3008-MB30A is a state-of-the-art compact, lightweight image sensor head that resulted from the combination of ROHM's LSI circuit technology and thermal printhead mounting technology. The IA3008-MB30A is perfect for multifunction printers (MFP) or facsimiles that print on normal paper using laser units. Applications Facsimiles Image scanning devices Features 1) The amplifiers, resistors, capacitors, and other discrete components that were normally externally attached, are built into the sensor IC. 2) Compact body and lightweight achieved by the placement of the LED light source and sensor IC on the same board. 3) Uses a special flame that provides superior light gathering characteristics and uniform light dispersion. 4) Uses a ceramic board as the base board for minimal temperature fluctuation and uniform thermal dispersion.
