I printed more than 120 labels through the manual feed tray, printing 50 a day. On the third day, a problem appeared.
When you try to print through the manual feed tray, a message appears about "paper jam". When it prints occasionally, it prints a sheet, while bending the upper right corner of the sheet. When you shine a light into the manual feed tray and look at it while printing, you can see that the paper moves very hard from its place (a problem with paper advancement).
What should I do?
My guess is that I need to clean the paper feed rollers, either all of them, or on the right side (where the corner of the sheet is crumpled).
If I am right, tell me what and how to clean
