Epson L3150 Service Required Error
One of the most searched Epson L3150 printer errors is the “Service Required” message.
The Epson L3150 Service Required error usually appears when the printer’s waste ink pad counter reaches its preset limit. The printer stops working to prevent ink overflow. Resolving the issue generally involves servicing or replacing the waste ink pads and resetting the waste ink counter using appropriate maintenance software.
What Is the Waste Ink Pad?
During:

- Nozzle maintenance
unused ink is directed into an absorbent waste ink pad inside the printer.
Over time, Epson estimates the pad has reached its capacity and displays a service warning.
Symptoms
- Service Required message
- All indicator lights flashing
- Printing disabled
- Scanner unavailable
- Error shown in Epson Status Monitor
Can You Continue Printing?
Usually No.
Once the internal counter reaches its limit, the printer locks many functions until the maintenance issue is addressed.
