Thank you for the feed-back. Sadly I'm out of ideas of what might cause the error.

do you think I could use a valve cam sensor from another model...Pixma MG5350 for example or from a MP610?

I don't know. I have no documentation for the MG5350, but the purge units for the MP610 looks differently from the purge unit for the MP620. So I guess the sensors will also be different.

Hello PeterBJ,
I'm back... I couldn't threw my old MP620 away.
I'm sorry!!
Then I decided to keep on my investigations and after many Hours trying different ways, I totaly took the Purge Unit out of the Printer and dissassambled to clean it manualy, pieces by pieces.
I took me 2,3 days and I brought it back to Life.
No Error message anymore. The little switch was responsable I guess (see the pic. in case some one would be interested in).
A lot of Work and a lot of Concentration needed.
One more time thank you so much for your support and your Help.

I'm impressed. 
Was the faulty switch similar to those found in older printers like the iP4000? I admit I have dumped a similar Canon printer with a 6C10 error instead of taking it apart and trying to repair it.

the interest thing is that the switch didn'work properly as I mesured it with my Multimeter.I'm impressed.
Than I sprayed contact fluid and it worked again.
I admit too, I Ieft my MP620 on the side for more than 2 years... and the purge unit seemed to be complety clogged with old Ink as I cleaned it.
Now the printhead is clogged too.
I clean it with wash fluid + amonium + isopropanol... Unfortunately I don´t get the Black pgm back.
Do you have the Pharmacist solution fluid proportion in mind?
I forgot the proportions.

Forget about it ...I found it again.
By the way... The MP620 purge unit is similar than the MP550 one, than the switch is the same too.

Ok, one little tip: A drop is per definition 0.05 ml, so 20 drops equals 1 ml. This means you need to add one % of ammonia. If you want to prepare 1 litre of cleaning solution then you should use 10 ml of ammonia. Instead of counting drops it is easier to measure the ammonia with a syringe or pipette.

Perfect.
I'm gonna prepare some fluid.
Any idea concerning the Msg "printhead not recognized..."?
Even if it's an original Canon QY6-0073?
