Hello,

I have a strange problem with my printer. It prints fine but when I send items in the post that have been printed on this printer and if they are folded over the ink transfers from one page to the next. Is there a setting I can change to rectify this or anything I can do?
Thanks,

[Brian]

It seems like the fuser isn't doing it's job properly.
I'm not sure if the fuser temperature can be adjusted in the setup, it can in some types of printer.
