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.
