Canon IP3600 error B200

[Japanat]

Hello.
A friend of mine gave me this printer to see if I can fix it, and after tinkering around I found the service manual that states that to fix it I must change the printer head and the power supply.
So I ordered a new printer head and changed it, to no avail.
He gave me another 2 not working printers, still IP3600, one has the same problem and the other has a different problem, so I tried to get the power supplies from those other two and tried it on the first one, still to no avail.
On the service manual I missed a part, where it states that with the printer head you have to change the logic board, so I removed the board with the USB plug (I hope it meant this board) from the printer with a different problem (not B200 related) and installed on the first one, also swapping their PSUs. Still no avail, still getting the B200 error.
I'm not a printer savvy, I usually don't work on them, even tho I like this kind of modularity on those printers, anyway I'm stuck.
I downloaded the Canon Service Tool, two versions, the v.1030 and the v3400, I found by myself how to set the printer in service mode (holding the second button while connecting the power cable, I hope it's correct), and the tools seems to recognize the printer, but I didn't dare try to do anything yet since I don't know what to do.
Can anybody help me, please?
P.s.: I tried to read other threads here but I didn't get much of help, but maybe I missed something.
Thanks.

The IP3600 is a pretty ancient printer model more than 10 years old; the B200 error is the typical printhead failure which in lots of cases damages the motherboard as well.

I would not spend any effort anymore on such printer and rather look for a new printer - as a megatank or cartridge based model - with user replaceable printheads and waste ink /maintenance box.

I know but I already spent money on the printhead and I don't want to waste them.

Ink stained Fingers has given you the very best advice available here and things won’t get any better if you persist, O’ have fun while it lasts..

I know but I already spent money on the printhead and I don't want to waste them.

These print heads you purchased are totally useless and are second hand refurbished ones to look like new, buying print heads from any other source other than Authorised dealers are a waste of time and your money..

Printers of that age have long since been discontinued and no print heads are available for a long, long time, best advice is to contact the seller and seek a refund..
