Colour laser printers have a lot of benefits over inkjets, but the latest models have computer chip enforced toner contracts (so you can only buy expensive “genuine” toner). I picked up a Samsung CLP-300 2nd hand for $20 that allows generic toner. Low cost non-OEM cartridges are $20 per set on ebay delivered for 3 colours + black. This particular model, and it’s network enabled sibling the CLP-300N, suffer an annoying paper feed bug that means they are readily available for sale 2nd hand. The pick-up roller gets dirty/worn, and the paper feed fails, often sporadically. This link includes some instructions for fixing this error, and I’ve reprinted the key section below:

1- turn off and remove power cable;
2- remove paper drawer;
3- remove image unit – don not let it under sun light. cover it.
4- put the printer upside down;
5- look at the axle of the big central rubber roller:

5.1- you will see both sides have a plastic balancer and locker.
5.2- left one has a small “finger” that locks it from slide.
5.3- take your cellphone and do a photo of the present position of the axle and the pieces as you will need to remember it after.

6-light and carefully, lift this small finger from the axle and slide the locker half inch to the center;
7- after this, you have the axlee in a so so free way. You can move (rotate) it, if you lift and free the inside gear at left end;
8- at the central drum, there is two locks, one each side. If you release them, you can remove a type of a plastic shell with the rubber belt attached to.
8.1- to unlock the shell you need to rotate the axle and position the locks in a convenient way. So, rotate it again, and so, remove the shell.
9-I removed the rubber belt, washed it with water only.
when repositioning the belt on the shell, observe it and put in a different position, as the slick area fits inside the shell, so a new surface is out.
10- mount it a reverse order.

The pick-up roller itself is available as a spare part on ebay from around $9. Search for clp300 roller.

A 10 minute fix makes these good as new.

I also came across the service manual. It can be downloaded here.
