What Is a Paper Jam?
One-Line Definition:
A paper jam is when paper becomes stuck inside a printer during printing.
Quick Example:
A crumpled sheet inside the printer can cause a paper jam and stop printing.
Full Glossary Entry:
A paper jam is a common printer error that occurs when paper becomes stuck and fails to pass through the device’s internal mechanism during a print job.
This can happen at various points along the paper path, including the initial pickup rollers that feed a sheet from the tray, the main transport area around the print head or drum, or the fuser and exit rollers that eject the finished page.
Jams are caused by a range of factors, such as using paper that is wrinkled, damp, or of an incorrect size or thickness for the printer.
Other causes include overloading the paper tray, foreign objects obstructing the paper path, or worn-out rollers that can no longer grip the paper effectively.
Most printers are equipped with sensors that detect a jam and immediately halt printing to prevent damage.
Why This Matters (Troubleshooting and Fixes):
Resolving a paper jam is a fundamental skill for any printer user, as it is one of the most frequent interruptions to printing.
If not cleared correctly, a jam can lead to more serious issues.
Tearing the paper while removing it can leave small, unseen scraps behind, which are guaranteed to cause subsequent jams and may require technical service to remove.
Pulling the paper forcefully in the wrong direction can also damage sensitive components like rollers and sensors.
Therefore, when a paper jam occurs, it is crucial to follow the printer’s on-screen instructions or user manual, which provide a systematic guide for opening the correct access panels and carefully extracting the stuck sheet.
Understanding the common causes also allows for preventative measures, such as properly loading the correct type of paper.
