Hi,
I need help determining the pin outputs of the encoder that I want to connect to arduino leonardo (where is -, signal 1, signal 2, +). This is an encoder used in Canon Pixma TS8051/TS8251/8151/8350 printers with markings (QM7-4930) (QK21838). I have already burned one of these due to a bad connection and I would like to avoid this mistake again, but I cannot find any technical documentation and I do not have enough knowledge to determine what is what. I am posting photos from both sides.

An encoder will, well, encode it's movement. I do not see part in the pictures that move. Perhaps a better picture will show the movement and how that is encoded.
its something like this: https://down-id.img.susercontent.com/file/ee08dcfae82286792f7b409850e1c5ca in black part on brown site is place for timing disc - disc is moving part
Looks like it has one LED and two photodiodes or phototransistors as detectors:
You could use a DMM to figure out the polarity of the LED and then draw a schematic.
Look at the link you posted. Do you see anywhere they call that an encoder?
If I touch the marked pins with a multimeter set to diode mode, instead of 1, the multimeter receives 444 or 517, but after a while the result changes to 1 again. If I touch it the other way around, nothing happens and it still shows 1, so it seems to me that + and - I managed to find out, am I right? If so, the mystery remains as to what signal 0 and 1 are, and there are 5 pins, not 4
"Look at the link you posted. Do you see anywhere they call that an encoder?" - i see incremental encoder - sensor + timing disc, look:
But that was not the original question and picture, was it? All your device cares about is knowing the spin direction, which is determined by the order of pin pulses which Det1 and Det2 will tell you. Is the order 2 and then 1 or is the order 1 then 2? Then count the pulses form the first pin to give you the signal.
Hi, @marfuk123
Have you got the encoder disk that fits in the sensor?
If the sensor disk has fine marked gradations as the one pictured in post#6, then you will have problems using it unless you have the disk.
That disk is a printed disk, so possibly hundreds of pulses per revolution.
