I have been researching on the internet about a metal taste in my mouth. We just moved to a new location and instead of a large room with a lazer printer in it and a copies in the hallway, both copier and printer are in a small room across the hall from my office. Almost everyday I get a metal taste in my mouth. It is much worse when heavy printing is being done. My doctor does not think it is from the office but I do not get this taste on the weekends. I am going to continue investigating an allergy to ink!
