What It Is: The PW (Paper Width) Sensor - a small optical sensor that detects the edges of the loaded paper so the printer can confirm the correct paper size/width before printing. A faulty PW sensor causes paper-size mismatch errors, misaligned margins, or the printer refusing to start a print job even with the correct paper loaded.
Part Number: 2181521 / 2186324.
Condition: Refurbished Original / Pulled Original - professionally tested and working.

Note: This row overlaps in compatible models with row 19's "PW Sensor" (Epson M2140/L6460 in both), but the two rows carry different part numbers - kept as two distinct listings rather than merged, since each row's part number identifies a genuinely separate SKU.
Note: This entire listing is a byte-for-byte duplicate of batch 23's Products_17.xlsx (identical title, description and image) - this whole upload (all 30 rows) matches batch 23 exactly, the first time an entire batch has turned out to be a 100% duplicate of the immediately preceding one. Reused batch 23's suggested content verbatim.
