What this means
Paper is trapped in the printer path. A jam error means a sheet broke the timing of the sensors along the route. The error does not point to the exact location of the obstruction, and a tiny scrap left behind means the problem remains. Clearing the visible sheet does not fix the machine. Torn paper on optical sensors continues to trigger jam errors even when the path looks empty. Do not pull paper backward against the feed direction. That damages internal gears and turns a simple blockage into a mechanical failure.
Common causes
- Overloaded paper trays
- Worn feed rollers
- Incorrect paper type or size
- Moisture in the paper stack
- Torn paper scraps left inside
- Misaligned paper guides
What to check first
- 1Turn off the printer before touching internal parts
- 2Check all paper trays and remove loose paper
- 3Open the main access doors to locate the jam
Step-by-step fix
- 1
Power Down and Open Access Doors
Turn off the printer using its power button and unplug the power cord. Open all rear and top covers to expose the paper path.
Never work on a printer while it is plugged in.
- 2
Pull Paper in the Direction of Travel
Grasp the jammed paper with both hands and pull it gently in the normal direction of paper travel to avoid tearing.
Pulling backward against the rollers can break internal gears.
- 3
Check Underneath the Paper Tray
Remove the main paper cassette completely and look underneath the printer for sheets caught in the lower feed area.
- 4
Inspect and Clean the Rollers
Wipe the rubber pickup rollers with a lint-free cloth slightly dampened with water to restore their grip.
- 5
Clear Hidden Scraps from Sensors
Use a flashlight to look for tiny paper fragments resting on the optical sensors. Remove them carefully with your fingers.
When to contact a professional
Stop clearing that jam and call a professional if the paper is wrapped tightly around the fuser unit. That component gets extremely hot, and you risk a serious burn. Stop immediately if you hear broken plastic gears. Forcing the rollers when something is broken inside only causes more damage.
