Connecting one SCSI device

C A U T I O N

To avoid damaging components, before you connect or disconnect a SCSI cable, turn off the printer, then turn off the SCSI device.

1.Turn off the printer and the SCSI device.

2.On the SCSI device, set a unique SCSI ID number (0 – 6; the printer is 7).

3.Connect the SCSI device to the printer:

a.Connect the SCSI cable to the SCSI device; you will need a high-density SCSI connector.

b.Check termination (not required if the SCSI device has a built-in terminator).

■The printer has an internal terminator.

■The printer must always be at one end of the chain with a terminator (or a device with an internal terminator) at the other end.

■Most SCSI hard disks are shipped with an internal terminator that is active.

■If the SCSI device does not have an internal terminator, add one.

N O T E

Devises that require power from another device (TERMPWR pin 38) may not terminate properly.

■ For scanner’s termination, refer to its documentation.

c.Connect the SCSI cable to the printer.
