Hp laserjet 4000/4050/4100 series - deleting duplexer function and going back to normal paper handling

I've acquired a good used HP 4100dtn mono laserjet that has a problem with the duplexer jamming when it tries to print a job.

Everything else about the printer checks out and it's basically in excellent condition apart from the duplexer issue.

To *delete* the duplexer and restore the printer to *normal* paper handling what do I need to get to replace the duplexer? If I can find another used printer esp another 4050 or 4100 without the duplexer I can grab the parts from it.

Anyone with deep knowledge of these high quality printers know where to get the suitable parts to remove the duplexer function?

Thanks.

Yes—if you want to remove the duplexer on the HP LaserJet 4000/4050/4100 series and return to standard (non-duplex) printing, you’ll need the rear output bin or duplexer cover, which replaces the duplex unit on the back. This is a simple plastic part that snaps into place and allows the paper to exit normally.

Look for a “rear output bin” or “duplex cover” from a base model like the 4100n or 4050n (models without a “d” in the name). These are often available used on eBay or printer parts sellers. Once installed, the printer will detect the duplexer is gone and stop trying to use it. At least should.
