Samsung printer ML-2240. If I load up with say 100 sheets x A4 it will print ok around 75 pages then it stops picking up the paper, If I top up the paper again to 100 sheets it starts picking up again and stops around the 75 sheet count.
Any thoughts on what to check on?
It normally indicates that the rubber pickup rollers are losing some "grip". A good clean with soapy water can help. Also get rid of any paper dust floating about in the printer.
If that does not fix it, or if the roller looks knackered, then you can get replacements. (ebay etc will leave you change from a fiver!)
There are some youtube vids on the actual change.
Thanks John.
Examine the way it picks paper up. Many do this with an upward pressure under the stack of paper near the back. This allows the rollers to pull the top piece out, but if the amount its rising is too small, or the roller has gone shiny due to paper dust, then it tends to either half do it and jam or not work at all.

+1 I've just cleaned the pick-up roller on my HP1320. FWIW I found IPA worked better than water (but test a small area first).
My samsung M2026 can do similar, it seems to prefer the paper is "fanned" slightly, rather than inserted in a solid block ...
An outside possibility that which way up you are using your paper is making a small difference. I have seen it do so on some printers.
The pickup rollers need cleaning but I honestly wouldn't bother until it gets a bit worse than that. 75% paper capacity usable isn't too bad.
I also have a Samsung ML-2240 and find that the brand of paper makes a difference. Sainsbury's paper often causes paper jams, while that from Tesco mostly works. They look and feel the same (and cost much the same) but I've found a consistent difference so have stopped buying Sainsbury's paper. No doubt other fine brands of paper will also work well.
I only use Tesco as it is usually the cheapest, have done for a few years with no issues but the `jamming` is just a recent thing.
Yup, IPA will work - it does depend a bit on why it's losing grip - if it's dirt and dust or the rubber is hardening a bit, then soapy water or a mild cleaning product of some form will work ok IME (the "Foam Cleanser" type aerosols are quite good as well).
If its greasy or has similar contaminants, then IPA will clean it better.
HP once sent out a paper pick up roller fix kit for one of their printers.
It was one of those green (dish) washing up scrubbing pads and was pressed against the rotating roller to rough it up a bit. This was to cure a problem where the paper wasn't being picked up.
Interesting, I've not seen one of those.
Back almost 20 years, HP sent me a very well designed and made kit for a different paper pick up problem. It was actually a Canon printer, but the mechanism was HP.
It consisted of a number of pieces of thick cardboard, scored and marked for folding. It formed up to make a rectangular tube that fitted down the almost vertical paper bay and another box that slid down inside it. A sticky pad was attached, sticky side out, to the box, pushed down and stuck, in exactly the right position, at the bottom of the bay. That provided just enough friction for the paper to be taken one sheet at a time by the roller, rather than 3 at a time and jamming, as the original pad had worn away.

I have cleaned the rubber with soap & water and will see how that goes when the paper pile is used up. Failing that I have now watched the utube videos for replacing it.
Well enough of that will help reach the "Stuff the printer" state of mind!
(although the IPA (the beer) is not a good source of IPS (Isopropyl Alcohol) the solvent)
Take a container to your local supermarket and fill up with hand gel for 'free' at the entrance :-)
It looks like the clean with soap & water has cured the problem.
Thanks all for the advice.
