Communications Diagnostics
If there’s a problem transferring data between the computer and the printer, try putting the printer in the Communications Diagnostics mode. The printer will print the ASCII characters and their respective hexadecimal values for any data received from the host computer (see Figure 29). To find out how, refer to “Feed Button Modes” in this chapter.
Feed Button Modes
Power Off Mode (Communications Diagnostics Mode)
With the printer power off, press and hold the Feed button while you turn on the power. The printer prints out a listing of its current configuration (see Figure 28). After printing the label, the printer will automatically enter a diagnostic mode in which the printer prints out a literal representation (see Figure 29) of all data subsequently received.
Power On Modes
With the printer power on, printhead closed, and Error LED off, press and hold the Feed button for several seconds. The Error LED will flash a number of times in sequence. The explanation at the right (Action) shows what happens when you release the key after the specific number of flashes.
Flash Sequence | Action |
A configuration label prints.
The media sensor calibrates and a media sensor profile prints (see Calibration and Figure 25).
The serial communication parameters are reset to 9600 baud, 8 bits per character, no parity, l stop bit, and XON/ XOFF.
Resets the factory defaults, auto calibrates, and saves settings into memory.
The print width is calibrating. While the Error LED rapidly flashes, a series of stacking rectangles prints on the label. When the rectangle prints to the outer edges of the label, press and release the Feed button. The label width and current communication parameters will be saved into memory.
If the Feed button is held down for six flashes and quickly released, the printer will ignore the button. For additional information, refer to the maintenance manual.
