Page 434 5060-00x Remove the old printhead and install a new printhead assembly. Do not tighten the printhead screws yet. Note: Make sure the right rear screw goes through the printhead spacer located at the right rear of the printer frame. Bias the new printhead assembly against the front and rear stops. Tighten the right rear printhead mounting screw.
Page 435 5060-00x Securely close the front cover or reattach if previously removed. If replacing the black printhead, go to step 12. Otherwise, enter Diagnostics Mode: Turn the printer off. Press and hold Go and Return. Turn the printer on. Release the buttons when Performing Self Test displays.

Reinsert paper tray into printer. If any fragments fall into the printer they should land in the paper tray and be easy to remove. Remove the broken pieces of old nip relief handle.
Page 445 5060-00x Remove any remnants of the handle. Check the paper tray to check for debris. For example, see the fragment (B) in the following picture. A-19 Appendix A—Service tips...
Page 446 5060-00x Installing the new nip relief handle Rotate the new nip relief handle into place to connect it to the nip relief link (A). Using a screwdriver, gently pry the nip relief lever (B) towards the rear of the machine and insert lower portion of handle so that it is trapped between the lever and the reference edge plate (C).
Page 447 5060-00x Holding the nip relief handle in place, use a flathead screwdriver to gently pry up on the top portion of the lever allowing the handle to press into place onto the post using moderate force. Once the handle snaps onto the post, press the upper portion of the handle to the right and rotate the handle into its home position.
Page 448: Finisher Alignment
5060-00x Finisher alignment This tip provides detailed instructions for aligning the finisher to the printer. The sides of the finisher must be parallel with the printer and at the same height, or you may have paper feeding problems. There are four locations where adjustments can be made to correctly align the finisher with the printer. There are two adjustment casters on the left (the side closest to the printer) and two on the right, underneath the platform cover.
Page 449 5060-00x • Tall finisher – Printer – Optional duplex unit – One additional 500-sheet drawer – Optional 2000-sheet drawer – Finisher A-23 Appendix A—Service tips...
Page 450 5060-00x Step 1: Secure the printer Completely stabilize the printer before the finisher alignment process is started. How this is done depends on whether you have a short or tall finisher. Short finisher Attach caster brakes (A) to the two back legs of the printer caster base. Screw the caster brakes onto the legs of the caster base.
Page 451 5060-00x Step 2: Align the pin Adjust the two casters on the left side (closest to the printer) to raise or lower the finisher as needed, so the pin (D) on the printer properly aligns with the hole in the finisher (the pin should freely slide into the hole). Short finisher Insert the Allen wrench (E) into either caster bolt (F).
Page 452 5060-00x Tall finisher Loosen or tighten the wingnuts (G) to adjust the height of the finisher (clockwise raises the finisher). Step 3: Align the bumper pads Adjust the two casters on the right side (under the platform cover) to raise or lower the finisher as needed so the two bumper pads on the finisher lightly touch the printer.
Page 453 5060-00x Short and tall finisher Lift the platform cover. Insert the Allen wrench (D) into either caster bolt (J). Rotate the wrench in the appropriate direction to adjust the height of the finisher (clockwise raises the finisher). Repeat with the other caster bolt. Step 4: Adjust the tilt If necessary, adjust the tilt of the finisher so that the front is flush with the front of the printer.
Page 454 5060-00x Step 5: Connect the finisher and printer Push the finisher against the printer, making sure the gap in the front is the same as the gap in the back. When adjoining the finisher and the printer, make sure that the finisher cable is out of the way of the paper path. If the cable folds itself between the finisher and the printer, disconnect the cable, twist it one time, and then reconnect it.
