Whenever we print envelopes to the Dell 5310n, it makes a loud knocking noise as the envelope feeds into the printer. We were told that this same printer is doing the same thing in our other office. What could this be and how can we fix this?
Re: Dell 5310n knocking noise when printing envelopes
This is a good thing. The 'knocking' noise is actually called a "Thumper". It's purpose is to get the air out of the envelope before it hits the fuser. Air in the envelope typically leads to creases on the envelope itself.

when you print envelopes you have to choose the envelopes in the printer settings then only machine knows that envelope is printing. when you don't select envelope in printer settings when you sent a print, the printer knows the a normal paper is coming through. the difference is that the envelope is a bit thick the normal paper. when envelope is selected in printer properties then the printer adjusts its settings to print on envelopes.
Haha, shouldn't be your wife this time :P It sounds like one of two things. 1. One of the rollers that pulls through the paper has come a little bit loose and therefore is starting to hit other things, causing said noise. This is why you only hear it when it when the printer is active 2. One of the rollers or gears has become stiff, and isn't spinning as should be. This could stop all printing all together, so it's unlikely to be this, but without looking at it myself, I couldn't say, sorry.
I'd advise looking at the rollers within the printer, to make sure they're not jammed, loose or stuck full of toner. Make sure you have the printer off for a while too, you don't wanna burn your hands off :)
if your getting this noise on every print job the fuser is usually the cause if they have been running on a bit hot they will get flat spots on the pressure roller and it will create a loud kind of clunking sound real common on lexmark lasers. it can also be an envelope setting on some lexmark lasers they have a solonoid for envelope feeding if the envelope inhancment is ingaged in the menu thiscan also cause such a noise
I have(had) the same problem using the Dell A920 printer on a Dell compunter running XP. After spending a hour trying to find a solution on the internet, I finally found a solution on my own.
When ready to print a envelope.
Go to File/Print
Click Properties button
In lower right hand corner, check "Print Color Image in Black and White" box
Click OK button
Click OK in print pop up
When finished, repeat to uncheck "Print Color Image in Black and White" box to allow for color printing.
