Fax
The L1 common interface Fax (ICF) has an optional 1 or 2 line fax module located in the image
processing module draw beneath the scanner.
The fax PWB is fitted with either one or two MultiTech MT9234SMI modems. The PWB sup-
ports fax modem reset control, presence indicator, audio volume control and board revision
information. The Fax PWB is connected into a fax connector PWB, which in turn is connected
by a ribbon cable to the single board controller PWB.
The fax is controlled by the copy and process controller on the single board controller PWB.
Fax functionality is selected and controlled via the main control panel.
Three Tray Module (3TM)
Overview
The three tray module consists of three trays. Figure 1 shows the positions of the trays.
Trays 1 and 2 are adjustable between A5 SEF and 11 x 17 inch SEF. The paper stack is loaded
centrally in the tray and the side guides move jointly and an equal distance relative to the cen-
tre of the tray. Movement of both the side and end guides are moved individually by the cus-
tomer using pinch grip / release handles. The slides have detentes at given sizes. In between
these standard sizes, the guides will still lock in position via a ratchet / pawl feature to support
custom sized media.
Tray 3 is a dedicated size tray, either A4 LEF or 8.5 x 11 inch LEF. The controller will supply an
NVM value to distinguish between the two possible sizes. The side guides and trail edge
guides in the tray to support the paper stack, are adjustable and lockable between the two
sizes. The paper tray is aligned with the centre of the paper path to the IME.
