Jerome Fine replies: I am still looking for some help as well. If you find anything, please let me know. I can't even find out if there are two fans! The fan right at the back left of the printer is easy to look at, but I was not able to get into the guts at all. To remove the cover, the display on the left "snaps" out to reveal a hold down bolt in addition to the other two in the front. But I was unable to do much more than just "look". Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.
