Power Switch. Located on the right-hand side of the printer near the back. The power switch should be turned off before connecting or disconnecting any cables.

Feed Key. In normal use, pressing the Feed Key once when the printer is idle (not printing) will cause the printer to feed a blank label. The Feed Key also activates a number of specialized functions which are described in Table 1.

Table 1: Feed Key Troubleshooting Modes

Power Off Mode (Communications Diagnostics Mode)

With the printer power off, press and hold the Feed key while you turn the power on. The printer prints out a listing of its current configuration (configuration label). See Figure 5 on page 20. For best results, use media that is at least 4” wide by 4” long. After printing the label, the printer will automatically enter a diagnostic mode in which the printer prints out a literal representation of all data subsequently received (hex dump mode). To exit this mode, turn the printer power off.

Power On Modes

With the printer power on, printhead closed, and Fault light off, press and hold the Feed key for several seconds and the Fault Light will flash the following numer of times in sequence. The explanation at the right shows what happens when you release the key after the specific number of flashes.
