Hi everybody!

I got some problems with my home inkjet printer, a CANON PIXMA IP 1600 (identical to IP 1200, 2200, 2600, 1800, 1880, 1980 etc. for parts fitted thereon, other than to other models of MP series).
It seems that paper cannot be fed lately. Previously, multiple sheets were fed simultaneously, so I needed to keep all the sheets lifted except for the one that was going to be printed (pretty annoying when I had a discrete number of pages to print...).
Being a home printer (with a quite discontinuous necessity of printing), I just went on like this for a long while, then I've recently noticed that no sheet can be fed.
So I tried to perform roller cleaning from the printer driver and clean the paper feed rollers with moistened cloth but both actions turned out to be useless.
I guess the paper feeding mechanism got broken, since the lower roller can't even come up.
Having removed the paper feeding unit, I managed to take some pictures of it.

As we can see in the first picture, there's an upper and a lower roller.
The first one spins without moving vertically, while the second one should even move vertically.
In the second photo I took, you can see the bottom of the paper feeding unit.
With the third picture I'd like to explain what I observed by moving something in the paper feeding unit.

By pressing the two little ledges (which I numbered 3 in the first picture), the rod 1 goes down but the tooth protruding from the same rod (I marked it with a blue line) doesn't touch the rod 2.
Behind the rod 2, I noticed a small lever (which I highlighted in red), able to move forward thanks to a small spring. The fourth picture shows this lever (V shaped) more closely, partially covered by the rod 2.

The first thing I'm interested to know is whether this lever must be in its current position or hook the tooth protruding from the rod 1. At the moment, the V lever is right below the tooth and it doesn't seem possible to force it to a different position.

Another thing I noticed (see the fifth picture) is that the rod 2 ends on the left side with a lever that, when I move the rod 2, seems to move in vain without hooking anything.
In my opinion, we have 2 different options:
- something that is hooked by this lever comes out only when printer is on and gives the command to feed paper;
- something has come loose (or broken) internally.
Otherwise, I can't believe that a lever with a tiny tooth at the end moves in vain without hooking anything.

I hope to get some useful answers to overcome this paper feeding problem. Thanks a lot!

Maybe a service manual and a special service tool for this printer will be helpful? You find links in this post. The links are still active, I just checked them.

I think image 2a shows that the ink absorbers are overfilled and close to overflowing. Maybe this ink is causing the problem?

Thank you for the service manual and tool for my printer.
So I've just cleaned the waste ink pad and performed a reset of the counter but the main issue has to do with the lower roller, still unable to come up and match the upper roller. I suspect it's something related to a couple of levers, probably accidentally moved from their original position.
I need to carry out further tests to figure out this particular situation.
