2. Refer to Figure 4-34. Reconnect the ribbon/head open sensor connector to the main
logic board (P4). Install new tie wraps in the same locations as previously removed.

between the ribbon/head open sensor assembly and the printhead mechanism
assembly when closed. Once this distance is achieved, tighten the mounting screw.
4. Install the electronics cover. Reinstall media and ribbon back into the printer. Close
the media door and reconnect power to the printer.
5. Turn the printer On (l) and unlatch the printhead mechanism. Look at the front panel
to ensure the error LED flashes. Close and latch the printhead mechanism and print
a configuration label using the Cancel Key Self Test to ensure the sensor and printer
work properly.
