Greetings,
I have found much linear/rotary encoder from printers such as Canon, Epson and HP. Now I wish to be able to read the signals by powering up these devices and play with them for a while.
Having done some work, I manage to find the pinout and conisder " they are right".
I have some trouble with the concept of pull up/down resistor with the application of digital signal.
Do I need to add some 2 pull up/down resistor from DATA1/2 to avoid floating issue? How should I connect them?
Here's the file and the picture.
Thank you for your time.
