6. Points to note when using the printer
1. When turning on the power switches, be sure to start with the external devices and then the
Printer. To turn off the power switches, be sure to start with the Printer and then the external
devices. If you turn on/off an external device while the printer is ON, noise can be introduced
to the Printer through the cable connecting the device and the Printer, causing an error in the
Printer.
2. Whenever connecting the Printer with an external device, be sure to turn off the power switches
of both and disconnect the power cords from the outlets. A fault can occur if the connector is
connected or disconnected while the power switch is ON.
3. Be sure to turn off the power switch of the Printer before installing or removing the following:
flash memory (option), Adobe PostScript Level 3 Module (option), expansion RAM DIMM (op-
tion), hard disk (option), built-in print server (option).
4. Be sure to use a shielded cable when connecting the Printer's parallel interface connector and
an external device. Moreover, make sure that the parallel interface cable is no longer than 3 m.
5. Be sure to use a twisted-pair LAN cable of Category 3 or higher when connecting the Printer's
10Base-T/100Base-TX port and an external device to a 10Base-T network environment.
6. Be sure to use a twisted-pair LAN cable of Category 5 when connecting the Printer's 10Base-T/
100Base-TX port and an external device to a 100Base-TX network environment.
7. Be sure not to touch the metal area of the connector before connecting or disconnecting the
USB cable while the power switch is ON.
8. Be sure to use SHUT DOWN MENU to shut down the printer if the optional Hard Disk HD-65
has been installed.
