FAX COMMUNICATION FEATURES
The fax driver makes print data from an application, then compresses the print data
using MMR. PJL commands are added to the compressed data and the destination
telephone number and the line selection are included in the PJL commands. The
telephone number can be taken from an address book application.
The fax driver uses TCP/IP protocol to transfer the print (MMR) data to the
machine.
Regular transmission
The machine stores the print (MMR) data in the SAF memory. Then, the print data
is transferred using the same method as memory transfer.
Print and transmission
The machine stores the print (MMR) data in the page memory on the controller.
Then, the machine decompresses the print data and prints out. The decompressed
print data is transferred to the FCU and is stored to page memory.
Even if the Expansion Memory is not installed, it is possible to transmit and print
the document from the PC with 400 dpi resolution. However, the data is converted
to 200 dpi and printed out if the data is stored in the SAF memory for memory
transmission. This is because the page memory on the FCU is not enough to
expand the print data to 400 dpi with only standard memory.
Using Document Server
First, the machine stores the print (MMR) data in the HDD. Then the print data is
transferred to the FCU. However, the FCU does not store this data in the SAF
memory. Then the print data is transferred using the same method as Document
Server transmission.
