I have a Samsung SCX-3405 laser printer and for some time now the sheets after printing or copying come out damaged. They are crumpled (rolled) at the end of the page (the part which comes last from the printer, about 1/5th of the page, some 2 cm). The top part of the page is fine.

enter image description here

This is not a mechanical damage like tearing for instance but rather something which looks like a malfunction of the hot piece of the laser printer (sorry for the non-technical terms). What is really surprising is that all the page is ok, the issue is only on the bottom 2 cm or so.

I think that this is more pronounced when the printer is not in use for some time (the sheets seem to straighten up when I print more in one batch).

The printer is ~2-3 years old and I printed out two cartridges of toner from it (it is not used much). The paper is standard printer paper, the same I used before without issues.

What could be the reason for such problems? Would it make sense, financially, to have it repaired? (the price of the equivalent model today is about 140 € = $160)

    Some papers are more susceptible to wrinkling than others. What kind of paper are you using? Also, this will happen more if the paper is damp, so what is the environment like? – hdhondt Sep 4 '16 at 16:34
  • @hdhondt: this is standard printer paper. The thing is that only the bottom ~1/5th part of the paper is damaged, the rest if fine. This paper was used all the time before and there were no problems. The environment is continental, nothing special. I edited the question to highlight that, thanks. – WoJ Sep 4 '16 at 16:39
  • Modern home office all-in-one printers are rarely worth repairing. The call-out fee alone is going to be more than half the price of a new machine. Find a teardown guide, spend a couple of hours with it in bits to see if you can figure out what's wrong, then just buy a new one. – Tetsujin yesterday
