CP2025/CM2320: Sub-PCA Upgrade Not Compatible with Old Board

The power supply sub-PCA is a small board beneath the main motor that relays power from the lvps to the fuser. HP made two versions of this board for the CP2025 and CM2320 which are said to be compatible. They are not.

Early brown boards, which have been discontinued, had two cable connectors on the left, while the later green ones have just one connector. Try to replace a green board with a brown board and you are left with a cable coming from the printer with nothing to plug into.

Can you just leave the extra cable dangling? No, you cannot. If you plug in only the upper connector (white wires), you will get a “50 service” error the first time you try to print, because there is no power going to the fuser. If you plug in only the lower connector (black wires), it’s even worse – the 115 VAC line voltage will be shorted directly to ground the first time you try to print! Obviously, neither of these is a workable solution.

So, if your customer's failed power supply PCA is brown, you have to get a working brown board. Although no longer available from the manufacturer, and a scarce part, we will try to keep them in stock.
