The first thing I noticed when rolling in my tools is the windows 8' tall by 25' wide, with a southern exposure, and the sun blazing in so brightly that I walked into a desk.
While my temporary blindness was receding, I was immediately reminded of a dentists office I had visited 15 years ago, that had glass on three sides, and the same 1 million watts of direct sunlight blazing in. That Mita DC1255 copier had had it's 3rd drum in a week. The blazing sunlight had found a crevice, through a rear fan opening and was light shocking the selenium tellurium drum for several hours each day. The fix, if you're curious was a miscellaneous cup shaped plastic cover I had lying around that fit over the vent and was glued on, with openings at the top and bottom to let the air flow.
The bizhub jammed every page exiting the fuser. For diagnostic purposes I tried covering the fan openings, but it still jammed. It took nearly 30 minutes out of the direct sunlight before the exit sensor PS3 started to respond correctly. My fix for this one was equally unorthodox. You may recognize the piece of bumper sticker that I placed, shielding light away from PS3 and the duplex sensor. It's small enough that it should not inhibit airflow. With the MFP rolled back in place, it worked like a charm.
