1-2. ADF Mechanism
The ADF consists of the feed roller, R2 roller, document/scan line sensors and separation rubber plate.
When a document is placed in the feeder, the document sensor detects it as explained in the previous section.
Then, the CPU switches the LED array on and turns the feed roller until the document reaches the scan line posi-
tion. After the handshake is completed or the Copy key is pressed, the feed roller feeds the document until the lead-
ing edge reaches the R2 roller (the machine scans the first 15 mm of the document). From this point, the R2 roller
feeds the document until the trailing edge of the document passes the feed roller. Both the R2 roller and the feed
roller are in contact with the document. However, the R2 roller turns a bit faster than the feed roller. After the trailing
edge passes the feed roller, only the R2 roller feeds the document.
So, the document is fed into scanner slowly during the first 15 mm, at the normal speed when the document is fed
by both rollers, then at a faster speed when the document is free from the feed roller. The magnification rate of the
scanned image varies in these three parts.
2. Printer
The printer mechanism for RF01F/02F is different from the FAX240F. Only the FAX240F has a cutter and decurler
unit.
2-1. RF01F/02F (Manual Cutter Models)
The printer is very simple. After printing has been finished, the machine feeds the paper 22 mm to the cutting posi-
tion. So, the received copies will have a 22 mm blank space on the top.
