Printers use various sensors and detection mechanisms to sense a paper jam. Here's how it generally works:
Paper Path Sensors: Printers are equipped with sensors strategically placed along the paper path. These sensors detect the movement of paper as it travels through the printer. If the paper stops moving or encounters resistance due to a jam, the sensor will trigger an alert indicating a paper jam.
Optical Sensors: Some printers use optical sensors to detect the presence of paper. These sensors emit light beams that are interrupted when paper passes through the printer. If the light beam is not interrupted as expected, it signals a paper jam.
Paper Feed Sensors: Sensors located near the paper tray or input feeder monitor the paper feed process. They detect if multiple sheets of paper are fed simultaneously or if paper is not feeding properly, indicating a potential jam.
Mechanical Sensors: Mechanical sensors, such as switches or levers, are also used in some printer models to detect paper jams. These sensors are triggered when paper physically obstructs their movement or position within the printer.
Error Codes and Alerts: When a paper jam is detected, the printer typically displays an error message or indicator light to alert the user. The specific error message may vary depending on the printer model and manufacturer.
Once a paper jam is detected, the printer may pause or stop printing to prevent further damage or complications. The user can then follow the printer's instructions to clear the paper jam and resume printing.
Overall, the combination of sensors, detection mechanisms, and error alerts allows printers to quickly identify and respond to paper jams, helping to maintain smooth printing operations and prevent damage to the printer.

∙ 10y agoA printer has different parts and gears working during printing. When they get stopped by e.g. a paper jam, printer knows there is some problem and it therefore senses a paper jam. There have been some printers who show paperjams when it is not, some problem with the sofftware.

I actually have this problem with certain printers. Sometimes it is because there is not enough paper in the tray but the type of paper can matter. I would avoid any heavy duty paper as really thick paper will jam a printer.

Provided the printer is working properly, the likely cause is usually poor quality paper (too flimsy), or paper poorly stored and allowed to become damp.
What does it mean if your printer is stalled?
Assuming that a paper-jam hasn't stalled the printer, is there a good cable connection. It could also be that there is a queue of data waiting to reach the printer. Try canceling the queue and restart the printer.

What is a paper jam?
A paper jam is when something is printing out, but the paper gets itself stuck (or "jam" itself) in the middle of the operation. These may be caused by misalignment of paper, by using low-quality paper (e.g paper that isn't even white, is too thin, e.t.c), or by having the wrong ink for the brand of printer. They are quite easy to solve - simply pull your paper out, and follow any prompts.
