Hello and thank you for choosing JA for your support needs. Sorry for the issue Sir or Madam. To assist you further I need to know the Model of Coping Machine?
Thank you Sir or Madam for that information. Now your Pick up Rollers must be cleaned. Please acquire two things, a can of Yale Rubber Roller cleaner and conditioner. This can be found at Staples, Best Buy, Walmart or any office store local to you. Also grab some Laser Printer cleaning sheets. These run through the Copier/Printer and removes debris from the Rollers.
Chime in and let me know of your thoughts..
