Warnings, Cautions, Notes
In this manual, the following important symbols and notations are used.
• A Warning indicates a potentially hazardous situation. Failure to obey a Warning could result in
death or serious injury.
• A Caution indicates a potentially hazardous situation. Failure to obey a Caution could result in
minor or moderate injury or damage to the machine or other property.
• Obey these guidelines to avoid problems such as misfeeds, damage to originals, loss of valuable
data and to prevent damage to the machine.
• This information provides tips and advice about how to best service the machine.
Responsibilities of the Customer Engineer
Reference Material for Maintenance
• Maintenance shall be done using the special tools and procedures prescribed for maintenance of
the machine described in the reference materials (service manuals, technical bulletins, operating
instructions, and safety guidelines for customer engineers).
Use only consumable supplies and replacement parts designed for use of the machine.
•
The Aim of Anti-tip Components and Precautions
The anti-tip components are necessary for meeting the requirements of IEC60950-1, the international
standard for safety.
The aim of these components is to prevent the products, which are heavy in weight, from toppling as a
result of people running into or leaning onto the products, which can lead to serious accidents such as
persons becoming trapped under the product. (U.S.: UL60950-1, Europe: EN60950-1)
Therefore, removal of such components must always be with the consent of the customer.
Do not remove them at your own judgment.

1. Replacement and Adjustment
Removing Trays
• Tray 2 weighs 27 kg (60 lb) empty. Trays 1 and 3 weigh 20 kg (44 lb) each empty.
• To prevent damage to the tray and personal injury, never attempt to lift a tray alone or without
attaching the carrying handles, especially if a tray is loaded with paper.
• Two people on each side of the tray should lift the carrying handles together to lift and move the
tray.
• Never remove the tray if the LCIT has not been docked to the copier. Removing the tray while the
LCIT is standing alone can unbalance the LCIT and cause it to fall over.
• Only one set of carrying handles is attached to the side of Tray 2. Follow the procedure below to
attach and use these handles to move Tray 1, 2, or 3.
1. Pull the tray [A] out of the LCIT until it stops.
2. Remove the screws from the right rail ( x3)
3. Remove the screws from the left rail ( x3)
• You do not need to remove screw for the stopper pin bracket at the back of the left rail.
4. Remove carrying handles [A] and [B] from the right side of the tray ( x 2 ea.)

Side Registration Adjustment
Normally the side registration of the image can be adjusted with SP1002-004 to -006 (Side-to-Side
Registration – Tray 1, 2, 3). When the punch hole positions are not aligned from a particular feed
station, adjust the side registration by changing the tray cover position for the tray, as described below.
Then adjust the side registration of the image with the SP1002.
Pull out the tray.
1.
2. Change the screw positions [A] at both the right and left sides as shown.
• Adjustment range: 0 ± 2.0 mm adjustment step: 0.5 mm/step
Double Feed Problem from LCIT
If double feed occurs several times when paper is fed from an LCIT (Tray 1, 2 or 3), try to change the
upper limit of the paper stack in the LCIT tray. Changing the upper limit of the paper stack in the LCIT
tray can improve paper separation for the paper stack in the LCIT tray.
1.
Remove the paper feed unit of the LCIT unit (page 13 "Paper Feed Units").
2. Loosen the screw on the paper lift sensor bracket [A].
3. Move the bracket 0.5 mm in the arrow direction as shown above.
39
1. Replacement and Adjustment
4. Tighten the screw on the paper lift sensor bracket [A].
• To return the upper limit position to the default position, move the paper lift sensor bracket 0.5
mm to the opposite side.
Return the upper limit position to the default if a paper jam occurs at the paper feed sensor in
