I have a LJ 4350 that will print an envelope and pause about 3 or 4 seconds in between printing the next one. It is running Windows 7. It has 336 DDR RAM on board. Client said it started printing slow after a technician came and looked at it one time. I have tried changing all the settings i could on it and it still prints slow. I have also updated the firmware on it. Any trouble shooting ideas?
