I recently acquired a Bessler 45mxt enlarger with an Aristo cold light head. The head looks somewhat tilted and not sticking straight down. I am not sure this is normal. It is taped with some gaffers tape around the top due to small light leaks from what I was told from the seller. The enlarger turns on fine and I was practicing focusing and setting the height, etc. The circle of light did not seem to project straight down, but rather seemed to fall off the front edge a bit. The circle of light seems large enough to cover the area I'd need, so is this an issue? I am really not sure how to check setup. The enlargers I've used up until now were all set up and I just focused/set height. Do I need to calibrate, and if so, what should I look for? If the head is a bit tilted, would it be fine to take off this tape, adjust it until it points straight down, and re-tape?
Thanks for any advice. If my questions sound really ignorant, please bear with me.
