Subject: Re: [Homebrew_PCBs] How to ajust toner darkness in HP LaserJet 4m plus printer?

From: Tobias Gogolin <usertogo@...>

Hi folks
I am wondering has anone ever tried to disconnect the fuser (the hot
chamber the paper runns trough to fuse the toner to the paper?
I have notices that when there was a paper jam the section printed but
not fused has the toner very loosly on the paper, which if it can be
handled without disturbing the pattern may result in a more complete
transfer of toner ?

cheers

Tobias

P.S>: It would be cool if sombody could figure out how to increse the
precission of the print offset (margin) so well that one could print 2
or more layers of toner?
