Removing the printhead

8-14 Phaser 600 Color Printer
Tools required
#1 POSIDRIV® screwdriver
1. Turn off the printer. Leave the power cord plugged in to provide a
discharge path for static electricity. Allow the printhead to cool; this
takes about 20 minutes.
2. Open the top cover.
3. Remove the right cover as explained in the earlier procedure, "Right
cover" on page 8-4.
Warning
The printhead is hot. To avoid injury, allow it to cool before
handling it.
4. Move the printhead tailpiece's slide ramp to the printer's right to tilt
the printhead backward slightly.
5.
Supporting the printhead carriage, disconnect the printhead's sensor
and heater wiring harnesses from the carriage board.
6. Loosen the right-side tilt-adjusting hex screw securing the printhead
in place. Back out the screw and its tilt plate far enough to free the
printhead. In order to not drastically alter the printhead tilt
alignment, do not loosen the left-side tilt-adjusting screw.
7. Supporting the printhead, gently remove the printhead's hybrid flex
cable from its connector on the carriage board.
