We have an officejet 8600 plus all in one printer and it's been a good unit. One day, a power surge came through and that was it. The printer was dead. We have 4 kids doing primary school, all needing things printed, copied etc. this was a family crisis, and demanded action!
I went through the power diagnostic advice from hp - I think a video on YouTube? I got to the point where my power supply is not replaceable and I should go see a service agent. My previous Samsung printer cost 250 to repair! So not going there again. So I had to find the power unit and replace it.
I then tried to find the name and number of the power supply component and tried finding a supplier. On aliexpress I found the right unit - a CM751-60045
So, here's the step by step on replacing it:
You'll need a T9 screwdriver.
Place the unit on its side with the power supply at the top
There are 2 screws that hold the cover on
Sorry that's oriented 90 degrees different to the first picture. I worked out the right way afterwards!
Unscrew those 2 screws and now we want to take that side cover off. Look at the underneath of the printer and you'll see a little tab:
Slide a little flathead screwdriver underneath and you'll then be able to allow the lateral movement you need to move the cover sideways.
Don't use brute force! Back on the pane with the screwdrivers, insert another flathead screwdriver and use that as the lever. Lever a little and the panel pops forward.
Now twist it up as there are two "hooks" on the underside of the panel at the top that you should swivel the panel up to disengage:
That shot shows the underside of the panel. Here's where I salute the engineers on this project. Look at the power supply: 2 screws to release, and one small plug, all easily accessible. Samsung - take note!
Screw number 1
And screw number 2
Unplug the cable, pull out the old unit and put in the new. Reassemble.
Hope that helped!
