Paper jams are one of the most frustrating problems that users face with printers. Whether you’re working in a busy office or printing homework at home, a paper jam can stop your workflow cold. What makes it worse is that paper jams often seem to happen at the worst possible moment—just when you’re rushing or trying to meet a deadline.
This guide will help you clear paper jams safely and explain how to prevent them from happening again. We’ll focus on techniques that apply to most printer types—especially Brother, Epson, and general inkjet or laser models.
What Is a Paper Jam?
A paper jam happens when a sheet of paper gets stuck inside your printer during the printing process. The machine stops working to prevent further damage. Some printers flash warning lights or display a message like “Paper Jam Inside” or “Jam Tray 1.” It’s the printer’s way of saying, “Help me out before I can continue.”
Common Causes of Paper Jams
Before you can prevent paper jams, it helps to understand what causes them. Here are the most common reasons:
-
Misaligned paper: If the paper isn’t straight or centered in the tray, it might skew and jam.
-
Overfilled tray: Cramming too many sheets into the paper tray can cause multiple pages to feed at once.
-
Wrong paper type: Using paper that’s too thick, too thin, or moist can lead to jams.
-
Dirty or worn rollers: These rubber rollers pull the paper through the printer. If they’re dirty or worn out, they can cause slippage.
-
Foreign objects: Sometimes small paper clips, torn paper, or labels get stuck inside.
-
Humidity or curled paper: Paper exposed to moisture might stick together or warp.
Step-by-Step: How to Clear a Paper Jam
Step 1: Power Off the Printer
Always turn off your printer before attempting to clear a jam. This prevents internal parts from moving while your hands are inside, reducing the risk of injury or printer damage.
⚠️ Never try to pull jammed paper with the printer still powered on.
Step 2: Find the Jam Location
Printers often display where the jam occurred:
-
“Tray 1” or “Paper Feed Tray” → front-loading tray
-
“Rear Jam” or “Back Cover” → exit path at the rear
-
“Inside Jam” → internal areas like near toner or rollers
Check:
-
Input trays
-
Output tray
-
Duplexer (for double-sided printers)
-
Rear panel
-
Underneath the cartridge or toner access area
Use a flashlight if needed.
Step 3: Remove the Jammed Paper
Use both hands to gently pull the paper in the direction it would normally feed. Avoid pulling backward unless the paper path forces you to.
Tips for safe removal:
-
Don’t yank—this may tear the paper or damage sensors.
-
If the sheet tears, remove all remaining bits. Even tiny scraps can cause future jams.
-
If the printer has manual feed rollers, rotate them gently to help release paper.
For multi-function printers (MFPs) with scanners, lift the top panel to access the path.
Step 4: Reset the Printer
Once all paper is cleared:
-
Close any open trays or covers.
-
Plug in and turn the printer back on.
-
Wait for it to warm up and check for any error messages.
-
Print a test page to confirm all is well.
If the jam message still appears, you may need to:
-
Open covers again and double-check for scraps.
-
Reinsert paper trays properly.
-
Power cycle (turn off and unplug for 30 seconds, then restart).

Turn off the printer.
-
If a jam occurs near the paper guide, gently pull the sheet out.

For continuous paper, tear along the perforation line before removing.
-
If paper is wrapped inside, use the manual knob on the side to roll it out—but only when powered off.
-
Remove the tension unit if needed and pull out the remaining paper.
-
Reset the paper-release lever to match the paper type before turning the printer back on.
⚠️ Don’t force the knob while powered on—it may damage internal gears.
Tips to Prevent Paper Jams
✅ Use the Right Paper
-
Match paper type and weight with printer specs.
-
Avoid old, folded, or moist paper.
✅ Don’t Overload the Tray

What Not to Do
Avoid these common mistakes:

Leaving scraps behind: Always double-check for torn corners or strips.
When to Call for Help
You should seek professional repair if:
-
The jam message doesn’t go away even after clearing.
-
You hear grinding noises or notice damaged rollers.

Paper constantly jams in the same location.
