Lexmark C4342 error 30.01: Tray Jam

The Lexmark C4342 error 30.01 signals that an obstruction has been detected in the input tray area. When paper fails to move smoothly or stalls immediately upon entry towards the rollers, the machine stops to prevent damage. It is a frequent code that is usually solved by checking for correct paper loading.

Solutions

Diagnóstico rápido

If the printer displays 30.01 when printing, the page has stalled right at the start of its path from the tray. Check for crumpled paper or tiny scraps left over from a previous session.

Solución paso a paso

  1. Tray Removal: Fully slide out the paper tray.
  2. Manual Extraction: Remove any jammed paper gently, avoiding sudden jerks.
  3. Guide Review: Adjust side guides to the exact paper size without overtightening.
  4. Quick Cleaning: Wipe dust off the rubber rollers.

Prevención y mantenimiento

Always use standard-grade paper and avoid damp sheets or those with staples. Keep the rollers clean and the environment dust-free to ensure proper grip.

Cuándo llamar a un técnico

If feed rollers spin but don't pull paper, or if constant clicking sounds occur, the pickup mechanism may be worn out.

Frequently asked questions

Extract the tray and check for paper scraps. Sometimes misaligned guides cause the paper to tilt and get stuck.

Do not overfill the tray past the max indicator and ensure paper isn't damp or curled.

Periodically clean the feed rollers with a moist lint-free cloth without harsh chemicals.

It is a routine jam. If it happens constantly with fresh paper, the rollers likely need a good cleaning.
