Fax Driver 1-3
Overview 1
1.1.2 Flow of the PC-FAX operation
Conventionally, faxes are sent by loading an original into a fax machine and sending it.
With the fax driver, you can send a fax directly from your computer without using any paper (PC-FAX
transmission).
Transmission commands sent from the application are received by the fax driver.
Data is transferred to this machine through the USB interface (when using a USB connection) or through the
Ethernet (TCP/IP or IPX/SPX) (when using a network connection), and then the data is transferred from this
machine to the image controller. Image rasterization (bitmap data created from output text and images) is
performed by the image controller. This data is stored in the memory of this machine and transmitted like a
conventional fax job.
