When your epson ecotank et-2850 is most likely to develop issues, based on community repair data and manufacturer patterns.

Problems that can appear early, often due to manufacturing defects or initial wear.
Users sometimes overfill ink tanks past the maximum line, causing ink to overflow into the printer's internal electronics. Ink can reach the main circuit board, the encoder strip, or the carriage motor contacts. Epson's tank design has improved with fill-stop valves, but the ET-2850's auto-stop can fail if bottles are squeezed forcefully.
The ET-2850 uses Epson's Micro Piezo printhead, which fires ink via piezoelectric crystals rather than heat. While more durable than thermal printheads, the dye-based inks still dry in the nozzles during idle periods. The printhead is built into the printer, not the cartridge, so a permanently clogged head means the printer is effectively disposable.
The rear paper feed design of the ET-2850 uses a single pickup roller that wears faster than dual-roller designs. Paper dust and humidity accelerate the rubber degradation. When the roller loses grip, the printer frequently fails to pick up paper or misfeeds.
