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.

Came across a product that can be used with legacy devices as an ethernet to wifi bridge:

Anyone used something like this?

@zonavar68 Yeah, I’ve used the IOGEAR GWU637 — it’s a handy little WiFi bridge for connecting older Ethernet-only devices to your wireless network. Setup’s pretty simple: connect it to a PC, log into the interface, enter your WiFi info, and you’re set. It tops out at 300 Mbps, which is fine for most legacy gear. Great for printers, consoles, or anything that just needs basic network access. Good luck!

@AnotherUniverse I've got the printer currently connected directly to an ethernet port on the back of my normal router and the connection works, but I can't get windows 10 to look for the printer using the IP address it's currently configured for (same subnet at my router). Win 10 does have a way to look up printers using IP address. If I manually update the printer list in Windows it still doesn't know about the 4100, and I haven't been able to find a PCL driver, at least not a HP supplied one.

@zonavar68 Ok. I don’t mess with Windows much if I don’t have to. 😊
I ran into the same thing with my 4100. It’s connected via Ethernet and shows up fine on the network, same subnet and everything, but Windows 10 doesn’t find it automatically—even when I search by IP. The trick for me was to manually add it as a local printer using a TCP/IP port. I picked “Add a printer,” then “The printer I want isn’t listed,” then used the IP address to create a new port. As for drivers, HP doesn’t offer a specific PCL driver for the 4100 anymore, but the universal PCL 6 driver worked fine for basic printing. Didn’t have an issue after that but also don’t have the machine anymore.

@AnotherUniverse I've managed to find a HP PCL6 driver that I was able to install and get working. I had to select 'generic PCL6 device' since the specific printer model isn't supported. It printed the test page out of Windows.

The printer is hardwire connected to my internet router. Happy it's working.

@zonavar68 Heck yeah man!!!
