How to Use the Tip-over
You can find two tip-over protection tools on the left and right sides of the caster base, and
also two tools on its back side. Pull them straight out, then turn them 90° counterclockwise
until they click.
When the number of additional tray units is three or more, completely pull out the tip-
over protection tools. If these tip-over protection tools are not set in place, the printer
might tip over and cause an injury.
Injury may result.
• When performing actions such as transporting this machine, replacing consumable and maintenance parts, or
setting paper onto the tray, please observe the following precautions to prevent the machine from tipping over.
- Do not push the output tray when the machine's output tray is open.
- Do not push down on the paper cassette while it is pulled out.
- Do not push the machine from the behind while the paper cassette is pulled out.
