Common causes

  • 1PDL Incompatibility: The file uses PCL formatting not supported by current firmware.
  • 2Corrupt Fonts: Documents with damaged embedded fonts that the processor cannot parse.
  • 3Obsolete Driver: Driver version incompatible with VersaLink protocols.
  • 4Memory Overflow: Extremely large files exceeding the processing buffer.

Solutions

Diagnóstico rápido

If the error occurs only with specific files, the issue lies within the document. If it occurs with all files, the installed print driver is likely incompatible or outdated.

Solución paso a paso

  1. Cancel all jobs in the local print queue.
  2. Update the driver to the latest PostScript or PCL6 version.
  3. Export the file as a flat PDF or image if the original remains problematic.
  4. Reset the printer memory by turning it off for 1 minute.

Prevención y mantenimiento

Keep drivers centrally managed in network environments. Avoid using non-standard fonts in documents requiring high print compatibility. Using original consumables, such as the 106R035 series, helps ensure the hardware is in optimal condition to process data without interruption.

Cuándo llamar a un técnico

If the error persists after reinstalling drivers and testing with simple text documents, the main logic board (ESS) might require a software update from technical support.
