I have an Lexmark Optra Color 1200 laser printer. It has some 22k prints on it and in the past, I was able to print envelopes left and right without a problem.
Now, I am having a very hard time printing an evelope that does not get smeared. I have changed the toner cartridges and photoconductors along with the fuser oil roll. I have installed and re-installed to cartridges hoping that would help. The printer prints fine on smooth paper up to 110 lb which is the heaviest paper that I have. Its the stupid envelopes.
