Original Detection; Scanning Section - Muratec MFX-2550 Field Engineering Manual

Document insert section / separator section
The machine scans up to letter paper size document width. Place the document to the center of the
document tray and align the document guide.
By pressing the start key through copy or transmission commands, the motor starts driving, and the
driving force is transferred to the pick up roller through gears, and the document will be fed.
Document separator section consists mainly of separate roller and separate pad.
The document will be fed from the upper pages. Remaining documents are separated by the friction
of the separate pad and only the top page will fed by the separate roller.
Register section (MFX-2570 only)
Following the document separation, the separate roller transfers the document to register section.
During this transfer, clutch 2 (CL2) which drives the register roller is turned off and the document
leading edge stops at the register roller. The separate roller feeds the document forward, and that pre-
vents the document to skew.
The document sensor (DRS) is placed between the separator section and the register roller to detect
the leading edge of the document.
When the document leading edge passes the sensor and the loop is made, clutch 1 (CL1) runs idle
(turns off) and clutch 2 runs (turns on) and the register roller transfers the document to the scan posi-
tion

Original Detection

The sizes of the documents are detected by the following sensors;

Document presence
Leading and trailing edge
detection

Scanning section

The document sensor (DS2) is placed at scanning position to detect the leading edge and trailing
edge of the document.
When the leading edge is detected, the feed roller transfers the document a certain steps where the
scanning begins. When the trailing edge is detected, the feed roller transfers the document a certain
steps where the scanning ends.
If the document has two or more pages, feeding of the next page begins when the former page scan-
ning ends, and the page is scanned in the same way.
The steps where scanning begins can be adjusted with machine parameter 013, and the steps where
scanning ends by machine parameter 014.
