Intermec PX4i Thermal Printhead Installation Instructions - Page 6

Installation Instructions (For illustrated instructions, refer to the printer's User's Guide). Note: If you are installing the 400 dpi printhead on the PX4i printer (Kit P/N 850-812-900 IPL Only), you must first update the IPL firmware to version 2.74 or later. 1 Switch off the power to the printer. 2 Open the side door (and the front door, if any). 3 Turn the printhead lift lever to raise the printhead. 4 Remove any remaining media and transfer ribbon. 5 Hold the pressure arm and press down the printhead bracket so it comes free from the magnet in the pressure arm. 6 Disconnect the printhead bracket by twisting it out of the print mechanism and pull it out as far as the cables allow. 7 Disconnect the cables from the printhead. Note the snap-lock on the inner connector. Pull at the connectors-not at the cables. 8 Check that the label on the new printhead corresponds to the label on the old one and connect the two cables to the replacement printhead. 9 Fit the printhead so the "fingers" engage the headlift shaft. Check that the cables run freely and do not prevent the printhead from being properly seated. 10 Turn the printhead lift lever so the magnet engages the printhead bracket. 11 Switch on the power, so the printer can reset itself to the characteristics of the new printhead. 12 Load a new supply of media and ribbon as described in the printer's User's Guide.
