Well as there's no answer to my own question, I'm going to give you some important information about.
Today I'm in touch with a manufacturer of industrial material for the absorption of hydrocarbon effluents. Not exactly the same because absorbents for hydrocarbons are hydrophobic but we get...
Well, after cleaning several times, it seems that changing them (any Canon Inkjet) will be a better solution than buying a brand new one. I've a lot of customers who want to buy a refurb one (half price of a new one).
Despite there's no more spare parts for most of them, have you tried to...
You should. Because you'll find in them quite all the solutions for repairing the new printers. The way an actual printhead is done is similar to an old one. Nothing new.
Just a question if you don't mind, do you think the EEPROM has a different use today than it did in the i965 service manual...
To be sure the problem doesn't come from the PSU. Diconnect it, and test it with a multimeter. You must put a voltage of 5 volts between pin 1 and ground (pin 2 or 4); use a 4.5 volt battery for the test (simulating the printer presence), testing "in the air" doesn't work.
The 3 first ones are online since this morning here's the link.
I'm going to add some other pages today. Anyway the link will remain the same, you just have to choose the one you need on the displayed page.
Enjoy your week end
I'm mainly repairing for customers (given gratis to friends, or people who need a printer but can't afford). I bought these one on Monday (15€) but not sure I'll pay the same price on a MB5xxx
Maybe I'll have an MB2150 in the next weeks for free. Then we'll see.
Even if I agree with you...
I've around 53 service manual. Most from quite old printers. I'm going to move them from my general site to another dedicated to printers only. It's free of charge, there are on my own server. When it'll be done, I'll post the link.
They have all canon, epson, brother spare parts just ask through chat if you don't know the exact PN. And also if you're out of GB as you can't register if you're abroad, so that you must ask for.
My case it's MB2050WI (WI for Waste Ink I presume ) ;)
