Use the exact message, not a similar model’s code
HP may reuse code formats across products while the supported action can vary. Use this model or an explicitly applicable manufacturer family as the source.
After clearing the condition
Retest the operation that triggered the error. If the same exact message returns after the documented action, move to the manufacturer’s next escalation rather than repeatedly resetting the printer.
