6.7.3 PAPER WIDTH AND MEDIA TYPE SETTINGS

After a roll has been installed, the width and media type must be selected on the
operation panel screen, and special settings input with user tools, before printing
from that roll. These settings determine machine parameters, such as toner supply
and temperature and pressure in the fusing unit (☛ 6.10.4).
To do the paper selection settings for the rolls and the cassettes, push [User
Tools]> "System Settings", then touch the "Tray Paper Settings" tab.
NOTE:
• "Tray 1" and "Tray 2" selections refer to "Roll 1" and "Roll 2".
• "Auto" for automatic paper size detection can be selected for either paper
cassette to detect standard paper sizes.
For more, please refer to the Operating Instructions.

6.7.4 ROLL TRAY FEED MECHANISM

Each tray has an independent motor that
drives the feed rollers and exit rollers for
the tray.
The feed motor [A] and feed clutches [B]
are on the left side of the tray.
There are two knobs [C] attached to the
timing belts on the right side of the tray to
allow removal of paper jams manually.

6.7.5 BY-PASS FEED MECHANISM

Inserting a cut sheet from the by-pass feed
table into the machine switches on the by-
pass feed sensor [A].
The by-pass feed sensor switches on the
drum motor, registration motor [B] and the
registration clutch [C], and the paper starts
to move.
The registration clutch switches off
temporarily so the user can adjust the
position of the paper. This delay time can
be adjusted with SP1911 (By-Pass Feed
Start Timing Adj.).
