HP OfficeJet Pro 8028 Paper Feed Gear Installation: Finding the Correct Position

Question: My HP OfficeJet Pro 8028 paper feed gear cracked and fell off. I have a replacement, but I cannot tell where the original sat or which way the new gear should face. How can I install it correctly?

Answer: Thank you for contacting BCH Technologies, and I am sorry for the delayed reply. Printer problems are urgent, and we want to give a careful, detailed answer rather than guess at the location of a loose part. Thank you as well for supporting BCH and our YouTube channel.

BCH lists the OfficeJet Pro 8028 among the compatible models for its paper feed gear (PFG). The gear attaches to the paper feed drive rod. Its job and location are described on the BCH HP 80xx PFG product page [https://bchtechnologies.com/products/bch-paper-feed-gear-pfg-for-hp-officejet-pro-80xx-series-fix-8012-8022-8025-the-print-carriage-cannot-move]. That page also directs owners to its inspection and installation video. Compatibility does not confirm that the replacement in hand matches the broken gear or establish its orientation in a particular printer.

Turn the printer off, disconnect its power cord, and remove loose fragments from accessible areas. Compare the replacement with the original pieces: bore shape, thickness, tooth count, and any molded shoulder or retaining feature. Locate the matching position on the paper feed drive rod and use the product-page images and installation video to compare the gear's face and its neighboring parts before fitting it. A photo of where the broken piece was found is useful, but it may not show where it was originally mounted. Do not hammer the gear, force the carriage or rod, or power the printer while loose pieces remain inside.

If the gear does not seat with the orientation shown in the installation material, stop. The shaft, retainer, or another gear may also be damaged, and forcing the part can make the repair harder. Send BCH clear photos of both faces of the new gear, the broken pieces, and the exposed rod and surrounding mechanism so the exact fit can be checked. If access requires deeper disassembly or the mechanism still binds after a correctly fitted replacement, professional diagnosis is safer than further trial-and-error assembly.
