No tolerance for paper wider than 8.5 inches EXACTLY

Summary: The problem people are having with paper jamming is the fact that there is zero tolerance for paper that is the slightest bit wider than 8.5 inches. If your paper is exactly 8.5 inches wide (or slightly less), the printer will work properly. Most economy copy and laser print paper is not exactly 8.5 inches wide. Such paper is about 8.53125 to 8.5625 inches wide. This will cause a jam in the ML-2510 every time. It is a design flaw.
Summary: A couple of months after putting in a fresh cartridge, the printer stopped feeding the paper properly, so after about 3 months use total it was no longer useable. Those first three months were fine, but after that the printer became useless. I've had HP printers that lasted a decade, so it was really frustrating to end up with a pile of e-waste after just three months. The printer only cost me $50.00 new, but it certainly wasn't worth even that much.
Summary: Purchased Samsung 2510 less than a year ago. Initial cartridge lasted 593 sheets - had to take it out a few times and shake it to get the extra 93 sheets. Printer worked great throughout. Bought new Samsung cartridge for $75 and now the printer prints 1 sheet and stops after pulling the second sheet in about an inch or 2. Cleaned pickup roller, disassembled it and reversed it, removed fuse on toner cartridge, reinstalled.. tried everything.

Summary: This printer has given me nothing but agony. It is nearly impossible to get it to print without jamming. I've had it for months. I've tried all types of paper, I've made sure to keep it on a perfectly flat surface with support under the paper feeder, etc etc - but it will not stop jamming.
Summary: Right out of the box and like many others the paper cannot feed. The whole printer just feels beyond cheap and now I have to deal with returning this. Many others on many sites have had this problem... I'm sure some are just fine, but why risk it. I had a brother before and will be going back... frankly the quality level has turned me totally off to Samsung products.
Summary: I originally ordered the product for my daughter. After setting it up, it jammed the first try I made a printout. Sad to say, not even one printout came out. I have had several printers already, but this one really sucks. Worse, the store I bought it from will not allow a refund once you already opened the box. Worse more is that the ink toner I bought with the printer cannot be returned unless I prepaid the shipping cost. Avoid this printer at all cost.
Summary: I am having the same paper feed issues as some of the other reviewers and it has been only a year (I print very occasionally). It worked great at first and I was really pleased it printed amazingly fast and I thought it was perfect for my needs. But now it is impossible to use, extremely unreliable, I never know when it will work or not. Paper feed stopped working and it does not matter what I do I can't get it working again.
Summary: I purchased this printer as a replacement for an HP laserjet 1200 which is getting old. I know that laser printers are notorious for drawing a lot of current but like other previous posters I had the dimming lights and even though I did not have the printer connected to my UPS, the UPS indicated that an event had caused a drop in voltage. Also, I too experienced problems with envelopes. Very unprofessional reults. Every envelope printed came out wrinkled.
