My HP PSC 4500 printer makes a loud knocking noise when first turned on which goes off after a few seconds and printer woorks okay

OfficeJet Printers have a "spittoon" in which a rubber pad is used to wipe the bottoms of the cartridges to maintain a clean jet nozzle area. To find this, the unit will go to it's home position, "bump" that side where the spittoon resides, to confirm it's home position, then wipe the cartridges before its ready for use. In other words: "That's a normal noise for this model of printer". It will happen every time you power it up or wake it from hibernation mode with a print job.

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.

Knocking noise

Remove the toner cartridge to hear if the noise goes away.

Pull the 2 caps with the arrows on them in the rear to check if the 2 Phillips screws are tight.

If you loosen those screws, you can pull the FUSER out and check the gears.

Knocking noise

sounds like the developper
it may start to stiffen up.
remove the developper (toner cartridge and try turning the gears by hand, if it's practically impossible to do) replace.
