how to stop envelopes from skewing and printing crooked?

[dkabele]

We just bought our HP Officejet Pro 8600 Plus e-All-in-One-Printer - N911g.   We are having problems with envelope printing coming out crooked.  We load the tray as directed but if there are more than one envelope in the tray, the printout is skewed.  My wife is ready to take the printer back already.  Any thing we're missing?

Does the paper rollers pull the envelope into the printer unevenly from the start of the print process? I would make sure that two sided printing was turned off, The pathway to check that settings is listed on page 44 of the user manual. Also, pages 38 cover all the settings to check to print envelopes in either Mac or Windows. I hope that this helps.

I have read many comments and solutions (tried them all) about this issue with the HP 8600 injet printing addresses crooked on #10 letters and I believe that this is an inherent mecanical problem with the printer. Here are the reasons that I believe this is a mechanical failure with the printer and not a software problem. The unit indicates it is aligned correctly. I have never had a problem with regular 8.5 x 11 inch paper. I have printed other wider envelopes on this same unit and they come out perfect. It is only the narrower #10 envelopes that come out crooked. When the envelope comes out of the printer it is already skewed. When ejected to the  output tray it clearly lands skewed to the left when facing the unit. Oddley enough this is the side that the open flap is on the envelope. When the envelope is inspected after printing that edge is  creased. The left edge when facing the unit. When envelopes were placed in the tray to print the edge is uncreased. It is evident to me that as the envelope goes through the printer the rollers put more tension on this flap compared to the opposite side. I believe that wider envelopes do not have this problem because they have more roller area contacting the envelope surface which prevents it from startig to skew. Six rollers near the print head have the possibility to pull the #10 envelope through the print head area. The first and last rollers have the ability to only contact the envelope about 1/32 to 1/16 of an inch and therefore if slightly miss aligned more tension is put on one outside roller or the other and the envelope becomes misaligned and the text is printed skewed on the envelope. In other words the outside rollers pulling the envelope through the printer do not have enough contact area. One side grabs more than the other and hence the crooked print, not a software problem....mechanical problem in the inherent design and spacing of the rollers. The rollers are spaced wrong for a #10 envelope and do not have enough contact area on the edges of the envelope. Should be easy for hp engineers to test it out if this is what is actuallyhapening.
