Page 23 7463 Adjustments Media aligner roller adjustment Complete the media aligner roller adjustment procedure when you replace the media aligner roller. Always print a copy of the Quick Test Page before making any adjustments to the media aligner roller reference adjustment screw. Note: When replacing the media aligner roller, back the reference adjustment screw out far enough to remove the old media aligner roller and install the new one.
Page 24: Polygon Printhead Mechanical Registration Adjustment
7463 Adjustment is typically 0-2 rotations. More than 3-4 turns, in either direction from the 20.5mm nominal spot, should not be necessary and may indicate other issues with the tray (such as problems with the back and side restraints), pick tires, or transfer roll mounting.
Page 25 7463 Install the new printhead with the mounting screws lightly tightened before printing the registration Quick Test Page to see if adjustment is needed. Before adjustment of the printhead, loosen each of the three mounting screws by a half turn. This will leave the screws loose enough to allow the printhead to move within its slots as the adjustment screw is rotated.
Page 26 7463 Locate the printhead adjustment screw access hole in the front of the printhead access cover. This will require a 3mm hex wrench to adjust. A ballhead hex wrench is suggested to make it easier to find the screw head. Check the Quick Test Page for any sign of misalignment by checking the diamonds at the bottom left and bottom right of the test page for equal distance from the bottom of the page.
Page 27 7463 Warning—Potential Damage: In some cases the adjustment process may take several tightening and loosening cycles of the printhead mounting screws. Care should be taken to avoid stripping the mounting screw bosses. Use only a manual hex head screwdriver, for this reason. When you have the correct adjustment, ensure that the printhead mounting screws are properly tightened, and print a final Quick Test Page for verification.
