Regularly paper jam

[east2100]

What's your HP 2300's really problems is so called as Sticky Solenoids.

HP 2300 has three Solenoids which control tray1/tray2/duplex respectively which has simple movement of open and close.

When it open it will hook the gears and paper won't be free to be grabed into machine.

When it close it will let go paper to go into machine.

All these opan/close are controlled by a critical timing but because of the Sticky Solenoids problem then its close timing take just a little more time so the pick-up reller turns more than one time maybe when it turns more than three times HP 2300 jams.

At least two papers jamed in the machine one is about to leave the exit , and another one jamed under toner cartridge. Maybe the 3rd one is jamed in the input tray and half of the paper just get into machine.

They are all caused by so called Sticky Solenoids.

Take a look on youtube the one which is very clearly.

Won't cost any money just your time.

I can't find 2300's so use a 2200's instead. They are almost the same but 2300 a little bit more difficult.

Google 2300's Service Manual it will be easier.

By the way.

If pick-up roller can't grab paper into machine properly which it will try two times.

Then the pick-up roller is needed to be replaced.

If the pick-up roller picks up more than one paper at the same time and all the time then the Separation Pad needed to replaced.

Pick-up reller often replaced timing is far more shorter than the Separation Pad in my experience.

Google HP 2300's Separation Pad & Pick-up Roller to see what they look like.

Hope it helps.

Unfortunately that isn't the solution. I cleaned them, but still paper gets jammed in the same position.

Possibly.  Probably.  It's difficult to say for sure without actually being in front of the printer when it jams, but here's my hypothesis:

If you're printing a multiple page document (say, three pages), and the printer BARELY manages to pick up the first two, but fails to pick up the third due to a slick pickup roller, The printer will throw a "paper jam" error even though the actual failure was an inability to pick up the third page.  The result in this case would be 2 pages stopped at various points inside the printer.  Bear in mind that this isn't the ONLY cause of the problem you're seeing, but it's the most likely, and it's where I'd start if this were my printer.

Good Luck!

P.S. 

On the 2300, you can often hear the machine struggling to pick up a page from the tray.  You'll hear the pickup roller "click around" once or twice before you actually hear the paper being pulled in.  If you can hear that, chances are high that you have a bad pickup roller.

Haven't tried this one yet, but i'll see if I can get the pickup roller somewhere cheap as the printer still gets the paper jammed. Sometimes it happens after 3 pages, but just now it happened after like 20 pages.

I don't know if you did it right or not?! I missed one thing that you have tray3 and it surely needed to be taken care too. If you don't use tray1 and tray2 then what i said before is useless for you. But they are all caused by sticky solenoids. Clean the sticky thing off or just let it be but insert a V shape of paper in between the two metals to avoid its sticky again. It never fails I have done that more than thousands of times in my twenty years printer fixing job.
