nary noise, smoke, heat and odor occur,
immediately unplug the power cord.
Be careful not to get clothing (ties, long
hair, etc.) caught in the machine as it may
cause injury. Should this occur, immedi-
ately unplug the power cord. Do not insert
fingers in the feed section while moving
the rollers.
2) Power OFF on disassembling
When disassembling and assembling are
performed, unplug the power cord.
3) Prohibition of modify
This machine must not arbitrarily be
modified or remade. If it is, use may be
forcibly suspended.

semble and reassemble this machine, fol-
low the instructions described in this
manual and the service information.
4) Electromagnetic wave interference
This machine complies with some stan-
dards regarding electromagnetic wave
interference, such as VCCI and FCC.
However, the user may have to take
countermeasures if the machine causes
electromagnetic wave interference.
5) “User Manual”

CHAPTER 1 GENERAL DESCRIPTION
III. USER OPERATION
This section presents an outline of the
scan operations and document jam clearing.
Refer to the “User Manual” of this ma-
chine for details. This machine includes 2
printed manuals; the “Easy Start Guide” and
the “Reference Guide.” The CD-ROM disc
contains the data of the “User Manual” in
addition to these manuals.
The machine is installed by the service
technician.
1. Preparation of Trays
Before scanning documents, prepare for
the document feed tray and document eject
tray according to the documents.
1) Document feed tray
When the power to the main body is
turned ON, the document feed tray opens
automatically and moves to the height of
the set home position.
Figure 1-301
Push the document guides from both
sides (
{
1) and adjust their positions ac-
cording to the document width (
{
2).
Figure 1-302
Note:The right and left positions can be
changed by locking the document guides.
Refer to the “User Manual” for the details.
Pull out the document feed tray extension
according to the document length.
