paper jam in duplex mode laserjet 4100tn

[willflow]

Hi There,

i own a trusty laserjet 4100tn stack with duplex.

when printing in duplex mode a paper jam occurs in the second page. 

After having  transferred the content of the second page, the paper jams while entering the fuser.

single sided printing never is an issue.

any clues?

Thanx in advance

Will

I'll try if its a sticky solenoid problem first.

Take out duplex unit and try to take off its cover especially the gears side to find if there's a solenoid or not.

If it is then use a paper folded into V-shape and put it into the solenoid's L-shape metal to block its getting sticky together again.
