Printer keeps jamming
When a jam keeps coming back, the most useful clue is where the paper stops. Start with fresh paper before assuming the printer needs repair.
1. Try fresh paper
Use a small stack of clean, dry, flat paper of the correct size. Remove curled, damp, damaged, or mixed-size sheets.
2. Check the tray
Keep the stack below the fill mark. Move the paper guides so they just touch the paper without squeezing it.
3. Notice where the paper stops
Right as it starts feeding: check the tray and paper pickup area.
Halfway through: check the normal jam doors and paper path.
Near the back or two-sided-printing area: check the rear door and make sure the paper size/type can be printed on both sides.
Near the output tray: make sure nothing is blocking the paper as it comes out.
4. Look for a small scrap from an earlier jam
Turn the printer off and check only the normal user-access areas. A tiny piece of paper can make the next sheet jam again.
5. If it always stops in the same place
Use the jam instructions for your exact printer model. The repeated location can point to a specific part of the paper path. There is no reason to reinstall Windows or Mac printer software for a physical paper jam.
