Samsung ML-2510 Printer. Picks up multiple sheets of paper most of the time.
I know this is an old post, but I thought I'd add this bit of info. I just fixed my ML-2010 by first replacing a torn pickup tire, but it still kept picking up multiple pages. I read a different post where the person traced it to a bad solenoid that was sticking in the open position as he described it. He replaced the solenoid, but on mine the solenoid was working, but I found it was sticking when closed. It is supposed to close and open once at the start of each page. Mine would close and stay closed sometimes until the start of the next page which would, of course, cause another pulse to energize the solenoid. I found it was due to a deteriorated thin half moon-shaped foam pad on the top of the solenoid's electromagnet that would cause the part that gets pulled in to stick to it for a couple of seconds before the spring would overcome the pad's stickiness and release it. I replaced the foam pad with a then piece of sticky-back felt that I cut to fit. When I reassembled it, it worked perfectly.
The way to get to the solenoid is to pull the covers, take the power supply boards off the back(as one unit, attached to a metal baseplate) and remove the panel underneath it, noting the screws and connections along the way. On the side where the solenoid is attached, I also saw a "split" gear that appeared to have a mark showing how they matched together, so be sure to realign the marks if they become separated before reassembly. Beyond that, it was a simple inexpensive repair. As these machines age, I would bet this is a major cause of this issue.
