The Epson L3111 EcoTank printer, like all inkjet printers, utilizes a maintenance box (waste ink pad) to capture excess ink during cleaning cycles. The printer tracks the estimated saturation of this pad via an internal counter. When this counter reaches a predefined limit (e.g., 100%), the printer displays a "Service Required" error (often indicated by blinking lights or error code 0x69) and ceases operation.
