My 8400 runs perhaps 60% of the time with the hood open - a folded piece of 5mm Kapa in the recess on the RHS by the bristles of the cleaning brush. Helps to see if there are head strikes, and to hold down the beginning of prints on papers such as Canson Platine Rag.
I do have to tell clients not to get too close, as had one try to point to a part of the print coming as it was running. Explained, that I pulled them out of the way, as the head would not stop, and I hate cleaning blood from machines. Also, be aware that after X number of prints, the printer will want to check nozzles and / or clean the head, and this needs to happen in darkness. You won't be able to close the cover when this starts, so be ready to kill the lights in the room.
