Safe checks, in order
Start with the simplest non-invasive check. Stop as soon as the error clears; repeated resets can hide a condition without correcting it.
Read the full message
Distinguish between a near-end warning and an end-of-life stop message.
Save pending work
Finish only the printing the manufacturer explicitly allows.
Check the exact model
Determine whether it uses a user-replaceable maintenance box or a service-only ink pad.
Arrange the correct service
Use the manufacturer procedure; do not reset a counter without replacing the serviced part.
Know where to stop
Do not open ink-pad compartments, defeat counters, or use a household vacuum on spilled ink or toner.
When to call a technician or support
Contact the manufacturer when the pad or maintenance component is not identified as user replaceable.
When you call, have the exact product model, the complete code or light pattern, and when it appeared.
