IMPORTANT
• We recommend an additional standard 120V/15 A outlet for service tools,
such as a laptop computer or vacuum that may be used when servicing or
configuring the machine.
• Use only dedicated and properly grounded outlets for the main unit. It is also
strongly suggested to use dedicated and properly grounded outlets for each
optional accessory. Do not use extension cords. The ground connection
serves to provide the internal electronics with a reference voltage. Faulty or
poor ground sources will cause this reference voltage to fall into a range
that no longer serves as a reliable reference voltage. The internal logic and
programming of the imageRUNNER ADVANCE DX C357iF Series
machines will not perform reliably because there is an insufficient difference
between the internal operating signal voltages and the poor ground
reference signal. A qualified electrician can measure and provide the ground
source that the imageRUNNER ADVANCE DX C357iF Series machines or
any computer controlled office equipment requires.
• Before installation, confirm that all necessary receptacles are available.
