Hello and thank you for choosing JA for your support needs. Sorry for the issue, but I must ask a few question before I can resolve your issue for you.
Where in your Printer do the Jams occur?
Please look for the following things:
Rubber Roller Cleaner for Martin Yale Folders, 13 Ounce Spray Can PRE200 It can be purchased at Walmart, Best Buy or any Office Store. Also, you need to acquire some Laser Printer Cleaning Sheets. These sheets are ran through the Printer and they clean the Pickup Rollers and remove any debris that may be attached to them.
Are you near the Printer now?
OK, we can continue this when you are free...
