Good morning

When I print a page my HP Laserjet 3800n often picks two or more paper
sheets from the tray. I have been googling for this problem but I could
not find the magic words to get a valid result.

I suppose it is a cleaning problem, but I prefer asking before dismounting.

Thank you in advance.

I just did paper feed repair on CP1518, easy enough if you can get
replacement parts.
