Hello again,
I tested and cleaned one more time the coin comparator.
I tested it with few more coins, i had to set the screw A for all 1 mark fit perfectly ( discomet, i started wrote this message before your answer, but thanks for the advice! I tried with euros and doesnt work).
On table, it's perfect.
Only one thing, for 10 pfennig, they are often returned because in back, one plate is not pushed on the comparator. I didnt find how to solve it.
I took on the machine and all coins are returned.
I saw its one thing on the machine, i don't know what, i show it on pic with scredriwer. If i let it push with screwdriver inside hole, it's work.
But.. sometimes i have alarm, so i guess this is for alarm?
Without screwdriver in hole, i have trouble..
