I have a MPC300 that the customer loads envelopes into tray 3. Lately the envelopes have been getting a wrinkle in them and occasionally not feeding in from tray 3. We are trying to figure out how to get this to go away. When I initially installed the device, it was printing the envelopes flawlessly. My tech says we needed to rotate them 180 degrees in the tray to change where the flap is pushing the envelopes up higher in the tray where the sensor detects them. We did this but we cannot get the address to print also with 180 degree rotation and the machine now "red lights" the printer button as well.
Any guesses or advice?
Thanks,
John
