Where does the printer stop?

Before paper enters

Focus on tray loading, pickup rollers, guides, and the entry sensor.

Paper stops halfway

Inspect the duplex path, rear door, and fuser or output path as the manual permits.

The carriage cannot move

Look for labels, scraps, or objects in the carriage path without forcing it.

Stop and get qualified help when

Do not continue troubleshooting if any of these apply:
  • The printer is a laser model with hot internal parts
  • A sensor lever or carriage component appears broken

Official support and model manuals

Use the full model number from the rating label. The manufacturer manual is the deciding reference when codes differ by region or product family.

Frequently asked questions

Can a tiny scrap keep the jam warning on?

Yes. A small piece can hold a paper-path sensor in the wrong position.

Should I use compressed air?

Not inside toner or ink mechanisms unless the manufacturer specifically instructs it; debris can be driven deeper.

Keep diagnosing
