we just installed a sprint, 48" wide and 8 feet of heat. just started testing and im running it at 375 degrees and the belt at 14 ft/min. i feel like im getting the ink to 320, but its really only in the chamber for about 35 seconds. is that too short of a time? using a temp gun and temp strips. wish i had a donut. whats anyones thoughts on the time in the dryer vs. just getting it to temp.
