Solutions

Diagnóstico rápido

If the machine hangs right after you hit print on a heavy file, the C4000 error suggests the printer CPU couldn't handle the data stream. A hard power reset should clear the fault.

Solución paso a paso

  1. Hard reset: Turn the unit off and remove the power cord for 5 minutes.
  2. Clear queue: Remove all pending files from the printer server or PC spooler.
  3. Firmware update: Check for newer firmware versions that improve data handling.
  4. Internal test: Print a diagnostic status page from the control panel to confirm hardware readiness.

Prevención y mantenimiento

Try to simplify complex documents before printing. Perform semi-annual firmware checks. Using genuine TK-1150 toner ensures that the printer communicates clearly with the drum unit and logic board.

Cuándo llamar a un técnico

If the error occurs consistently on power-up before any printing attempt is made, a mainboard memory fault is likely.
