AR-M208 SPECIFICATIONS 3 - 4
Top margin
The set value is received from the digital copier, and data are made
according to the set value.
Left margin
Since the paper size sensor is not set, the digital copier cannot recog-
nize the size and direction of paper which is actually inserted.
Therefore, the left margin is set according to the paper size specified in
the print data sent from the computer, and print process is performed.
If the computer does not specify the paper size, or in the case of the
custom size, the left margin is set according to the default paper size.
(7) Print reference
This machine employs the center reference system.
Since the digital copier is not provided with the tray size detection fea-
ture, formatting and center distribution are performed not by the actual
paper size but by the paper size specified by the computer.
D. Interface
E. System outline
The GDI-PWB is provided with IEEE1284 I/F on the host side, and the
16-bit bi-directional data bus I/F and UART on the machine side.
Transfer of image data with the IMC-PWB is performed with this 16-bit
bi-directional data bus. Command status information with the engine is
processed with UART.
This unit is installed to the position of PCL-PWB on the conventional
AR-235/275.
JBIG compression data sent from the host are transferred to the IMC
PWB, where the data are extracted to be VIDEO data, and sent
through the MCU PWB to the LSU.
