Scanner Assembly - OKIDATA OF2600 Service Manual

1.2.04 Scanner Assembly

The Okifax 2200 and 2400 use a 2048-bit element direct contact type image scanning sensor. The Okifax
2600 uses a 2432-bit element direct contact image scanning sensor. LEDs are located at the bottom of
the scan glass and image sensors are located at the top of the glass. When the document reaches the
scanning unit, it passes directly in front of the image sensor. The LEDs illuminate the document and the
light reflects back to the image sensors. This image data is sent to the printer control board via the main
control board. The transmitted document length is limited to 14 inches; however, the machine can be
modified for longer transmissions. (See Transmitting Long Documents in the Users Documentation).
Transmission will stop and a line disconnect will occur if the end of the document is not detected within 14
inches after scanning begins (unless the unit is set for unlimited transmission.) This message will be
displayed if the document does not reach the scanning position within five seconds after the start of a
document feed.
