HP laserjet 4 plus envelope printing

Hello!
Just purchased a used HP laserjet 4 plus with the intention of using it to print envelopes. I can not get it to print without crinkling my envelopes in the process. Any suggestions?
Thanks!

Nature of the beast. If you open the back door, the rectangular object at the bottom is the fuser. There are 2 metal levers near the bottom on the outboard sides of the 2 metal vertical supports. If you move the one on the right to the up position when printing envelopes, it will lessen the pressure on that side and lessen the creasing.

Best bet is to buy a Lexmark printer with "envelope enhance". Fusers in those printers have a solenoid which removes then returns the pressure between the fuser rollers three or four times as the envelope passes through. It sounds scary as in creates a banging noise, but it works.

Lexmark gurus will be able to advise which models have it (I know the early 'Optras' had it).

You're the first printer tech who's ever advocated the purchase of a Lexmark. I took apart a Lexmark M fuser last week and had to restrain myself from getting the hammer and smashing it to bits. You almost need 3 hands to reassemble them. It's not the first time I've had to restrain myself from smashing a Lexmark to bits. I feel pretty much the same way about Brother products as well. I think both companies target the bottom 2\% of the graduate engineering classes. They definitely aren't designed for ease of repair.
All the newer HP models use fixing film technology. I've never seen one of them crinkle an envelope.

Moe,

I thought it was just the LJ 4 that had those levers.
