HP LaserJet Pro 500 color MFP M570dn Conversion to Wireless?

[Joseph_Bruce]

Greetings:

With addition of internal wireless card and cable; is it possible to add wireless communication to my HP LaserJet Pro 500 color MFP M570dn?

Thanks,

Joe

Doesn't look like it...

You might want to consider putting a wireless switch next to it and cabling it to the switch.

SH:

I'd thought about a small switch; but I'm tight for space as it is and there's little room for one (poor palnning on my part).

What have you looked at to tell you that it's an unlikely fix?  I will probably be opening it up this afternoon.

Thanks and best regards,

Joe

The Specs for the machine and the options HP offers.

You could use some 2 inch wide Velcro to stick a switch to the side or back of the printer.

Plug-and-Play for me.  Your results may vary-

Steps:

• Google, find, download, and refer to CZ271-91020 This is the repair manual for the HP LaserJet Pro 500 color MFP M570dn.
• Find a wireless card and cable. HP is real good at “white listing” parts so that a given machine likely won’t use newer parts.  You’ll need: wireless card, matching connection cable; screw, glue, or tape.
• Referring to the repair manual; remove the side covers and then the back covers (top and bottom).
• Thread the cable through the rectangular hole in the frame, and plug the cable into the control board (jack at top of control board and below rectangular hole for cable in frame), and then into the wireless card.
• Turn on the printer and see if the card is found. If not; unplug the printer and try turning the cable 180 degrees as the polarization is nonexistent; or at least isn’t very strong on the plugs and cards.
• Once the card is recognized (you’ll see the icon in the display); decide how you’re going to attach it.
• I tried leaving the scanner attached; and had a hard time getting the screw tight enough with a right-angle screw driver to hold the card tightly in place; so I removed the 4 screws holding the scanner in place to gain access. If you can find a hex head screw; the scanner could stay in place.  Alternatively; you could glue or tape the card in place.  Even if it flops around; I can’t see that it’s critical to have it firmly attached.
• Use up all the screws reattaching the covers.
• Start using printer wirelessly.

Notes about parts:

• Wireless card 1150-7938 worked for me with the March 12, 2019 firmware update to my printer. Cards 1150-7953 (I expected this one to work) and 1150-7957 weren’t recognized.  Your results may vary; but I hope this helps.
• The cable you’ll need is about 4 to 5 inches long, and has 2 rows of 4 pins on each end (unless your card has something different). There is not enough room to mount the wireless card to the control board; and even if you did; it would be covered by a metal plate later (not good for radio waves).  
• The hole for an attachment screw is already molded into the case. I used a 3 mm x 0.5 pitch Philips head machine screw from the local hardware store to mount the card.  A similar hex head or hex drive screw could be used and could be installed without removing the scanner.  As the screw goes into plastic; a wood or sheet metal screw could also be used.  Glue, tape, or nothing could also be used and I would expect satisfactory results.

Conclusions:

• It worked.
• It didn’t work like I thought it would (required an older generation of wireless card).
• Wasn’t very hard to do (after gathering parts it took about an hour even taking pictures).

Good luck, and happy printing,

Joe

You could also get an HP USB>wireless jetdirect adapter that would just plug into the usb port of the printer.

Repairatrooper:

This printer had previously had USB communication issues; so using that bus was an issue.

The original question was; could a non-wireless printer be converted to wireless with card and cable.  The answer is; yes, it can; or at least it worked this time.

Not stated; but my issues were:

1) This became a stand-alone printer.  There is one single 117vac outlet; and I was told "No extention cords or splitters."

2) Several people need access to this printer; so it needed to be networked.  The 50' of CAT5e running along the floor was both unsightly and a trip hazard.

3) USB is not an option.

My solutions were:

1) Internal wireless card.

2) New printer.

I chose to look at option 1 as we already had the printer and a large stock of supplies.

Very nice guide and instructions, Joseph! Frustrating that HP sells this as wireless OUTSIDE of the US. I have 3 of these and many other HP LaserJets and these are the only newer models that don't have wireless as an option.
