Implementation notes (brief)
Every time you clean the print head (either manually or via automatic cleaning cycles), a small amount of ink is flushed through the nozzles to unclog them. This waste ink does not evaporate; it drips down into a spongy absorbent pad at the bottom of the printer. Epson programs a "lifetime" limit into the printer’s firmware (usually around 8,000 to 15,000 cleaning cycles or pages). Once the virtual counter reaches 100%, the printer locks itself to prevent the physical pad from overflowing and leaking ink all over your desk. Epson L3150 Adjustment Program Reset Tool
