Error 077-106 Xerox WorkCentre 7830: Paper Jam Guide

The Xerox WorkCentre 7830 is a high-volume color laser multifunction printer designed to optimize document workflows in offices and print centers. The 077-106 error is a paper detection-related code, specifically indicating an issue with the input sensor that fails to confirm the paper's path. Resolving this issue is vital to maintain productivity and prevent damage to the feed rollers due to failed print attempts. Proper maintenance ensures the paper transport system functions smoothly.

Common causes

  • 1Worn feed rollers: Rubber loses grip, preventing paper from moving toward the sensors.
  • 2Blocked sensor: Accumulation of paper dust or scraps preventing the sensor flag from moving.
  • 3Wrong paper configuration: The loaded size does not match the one selected in the panel, causing a safety stop.
  • 4Static residue: Static electricity causes paper to stick to internal walls of the path.

Solutions

Diagnóstico rápido

The 077-106 error appears when the machine attempts to feed a sheet but the tray exit or main input sensor fails to detect the movement. If you hear the feed motor sound but no progress is made, it is a clear indicator of this sensor or residual jam error.

Solución paso a paso

  1. Remove all paper from the main tray and ensure that the side guides are adjusted to the exact size of the paper.
  2. Inspect the paper path by opening the side covers to locate potential scraps of torn paper or accumulated toner dust.
  3. Clean the feed rollers (pickup rollers) with a cloth lightly dampened with distilled water to restore their traction.
  4. Restart the device by turning it off from the main switch and waiting 60 seconds before powering it back on.

Prevención y mantenimiento

  • Avoid using paper stored in high-humidity conditions, as it can stick to the rollers.
  • Perform a roller cleaning cycle every 50,000 prints.
  • Ensure paper weight is compatible (60-256 g/m²) per technical specifications.

Cuándo llamar a un técnico

If the 077-106 error persists after cleaning the rollers and checking the paper path, the input sensor might be faulty or misaligned. In this case, the component must be replaced by a certified technician.
