HP LaserJet IIP-Error Code 12

I have a HP LaserJet IIP with an Error Code 12. I also have a HP LaserJet IIP+ that I can use for parts. Can I swap the density control board from the IIP+ into the IIP? Any other problems this might cause? If you have some basic instructions to do this, that would be helpful also.
Thanks so much.

Part number RG1-1604-000CN is used in the following HP products.

Product name HP model number(s)

LaserJet IIP Plus C2007A

It's the board with the slide switch that adjusts the toner density.

You just take off the top cover and then you can figure out the rest.

Thanks, Stephen. I swapped the Density adjust board and the IIP works fine now. I really appreciate your info. - dansitarz
