The paper-pickup drive shaft in my printer has missing teeth. Is there a BCH video showing how to remove and replace it?

Missing teeth on a paper-pickup drive shaft or its gear usually call for replacement of the damaged part or assembly. Lubricant, glue, or forcing the tray cannot restore the tooth profile and may damage the mating gear. The question does not identify the printer model, so we cannot confirm the replacement part, disassembly sequence, or whether the shaft itself or an attached gear has failed.

Start by turning the printer off, unplugging it, and removing paper from the tray. Inspect only the areas you can reach without forcing covers or moving the mechanism. Look for loose tooth fragments, a cracked gear, a damaged mating gear, or paper scraps near the pickup rollers. Photograph the damage and the printer's full model label. Do not run repeated feed cycles while broken teeth are engaging, and do not use a replacement part based solely on appearance; shaft lengths, gears, and timing positions vary by model.

Our video about an Epson ET-8550 paper-tray problem shows the feed area, but it does not establish that your printer is an ET-8550 or that its shaft-removal steps fit your machine. Watch the original BCH video [https://www.youtube.com/watch?v=XEkItTcx920] and the drive-shaft access video [https://youtu.be/XkXv8XfW9bY] as visual references only. Search the BCH Technologies YouTube channel [https://youtube.com/@bchtechnologies] for your exact model and "paper pickup drive shaft" before opening the case.

Replacing the shaft may require removing covers and feed assemblies, preserving gear timing, and routing cables and springs correctly. If the mating gear is worn, replace or repair the affected assembly as well; a new shaft alone may quickly fail. A model-specific service manual and part number are the safest basis for the job. If the damaged part is deep inside the printer, the gears bind, or you cannot confirm the timing, ask a qualified technician to diagnose it.
