Brother MFC-J1010DW 16 ppm Wireless All-in-One Color Inkjet Printer with Duplex and Mobile Device Support ERR-A5 Error Fix: Machine Error A5 — Encoder Strip Issue

Error code ERR-A5 on the Brother MFC-J1010DW 16 ppm Wireless All-in-One Color Inkjet Printer with Duplex and Mobile Device Support means: Machine Error A5 — Encoder Strip Issue. Machine Error A5 indicates a problem with the encoder strip — a thin, transparent plastic strip with fine printed markings that runs horizontally behind the print head carriage. The encoder strip tells the printer exactly where the print head is positioned as it moves left to right. If the strip is contaminated with ink spray, fingerprints, or dust, the optical sensor cannot read the position marks, causing the print head to lose its position reference. Locate the encoder strip (a clear/translucent strip running behind the carriage) and carefully clean it with a lint-free cloth dampened with distilled water. Do not use alcohol as it can damage the strip markings. Support the strip gently while cleaning — do not bend or stretch it. If the strip is torn or has a kink, it must be replaced.
