Attention!

The Unit Emergency switch lets you turn off all power to the system in the case of an emergency.

Do not use the Unit Emergency Power Off switch to power off the system unless you have an emergency. Doing so can cause loss of data and hardware problems in the AFCCU.

Local/Remote Power Control

You can press the Remote and Local switches on the Power Control Panel to change power control from local to remote at any time. Local power control means that you can turn power on and off using the switches on the Power Control Panel. Remote power control means that you turn power on and off from another source, as shown in Table 6.

Powering On the System

You can switch power on for the complete system for duplex or simplex mode use. You can also switch power on for only one printer and its associated control unit in simplex mode when one of the two system printers is not operable and needs repair. In either mode and with the use of either printer, you must switch the AFCCU power on.

How you switch power on for the system depends on whether power control is set to Local or Remote.

Notes:

1.To switch power on for Printer 1 with Printer 2 powered-off, the AFCCU frame must still have power on.

2.The Unit Emergency switch in each printer must be in the Power Enable position before you can switch power on to that printer.

3.If a D208 error occurs after you switch power on for the system, do the following:

a.Switch power off for the system.

b.Wait two minutes.

c.Switch power on for the system again.

If you are operating the system in dual simplex mode and leave one printer powered-off, the D208 error remains on the powered-off printer window.
