HP PageWide Managed P77740 Printhead Assembly Install Guide - Page 12

10.7 10.8 When the assembly is fully seated, install screw PB1 (callout 1), PB2 (callout 2), and then PB3 (callout 3) to keep the assembly from moving. NOTE: Remove the flat-blade screwdriver, and continue the reinstall steps. After all printhead assembly screws are installed (in the correct order), remove the wiper shipping restraints, and then do the following: • Support the printhead bar (callout 1), and then disengage a spring loaded gear (callout 2; pull it toward the front of the printer). Make sure the printhead is fully raised, and then turn the manual wiper movement shaft clockwise (callout 3) to move the wiper away from the printhead (towards the right door). CAUTION: Do not move the wiper so far away from the printhead that the engagement rack disengages from the drive wheels. If necessary, see step 10.1. 10.9 Continue to support the printhead bar (callout 1), verify that the spring loaded gear is disengaged (callout 2; pull it toward the front of the printer). Make sure the printhead is fully raised, and then turn the manual wiper movement shaft counterclockwise (callout 3) to move the wiper to its home position under the printhead. NOTE: The wiper should move with little force required to turn the manual shaft. If excessive force is required to move the wiper, the printhead is not correctly aligned in the printer chassis. 12
