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

Turn off the printer first, then turn off the SCSI device.

On the SCSI device, set a unique SCSI ID number (0 – 5; the printer is 7 and 
the optional IDE internal hard drive is 6).

Connect the SCSI device to the printer:

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

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. 

■

For termination information on any SCSI device, refer to its 
documentation.

Connect the SCSI cable to the printer. 

Turn on the SCSI device first, and then turn on the printer.

If you have a SCSI hard disk, see “Initializing a formatted SCSI device” on 
page 105, and “Enabling and disabling Sys/Start Job execution” on 
page 106.

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