“Error – Failed to update preview” on Browser (BBUI) – TEKLYNX CENTRAL Error Message


This Error Message Article explains the TEKLYNX CENTRAL error message “Failed to update preview” and details how to fix the underlying problem that caused it to appear.


The TEKLYNX CENTRAL browser interface is unable to render the print preview image.  This can point to several issues including:

  • Connection to the Print Manager (SENTINEL)
  • Print Manager (SENTINEL) services are stopped
  • Print Manager configuration is incorrect
  • Browser timed out because Printer Manager (SENTINEL) was busy…need to try again


Start by checking the Print Manager (SENTINEL) to make sure the TCPreview SENTINEL is ‘Enabled’ and ‘Waiting’.  Study the Log tab for that SENTINEL and troubleshoot based on feedback from the log.
