HP HP Smart Tank 7001 All-in-One Wireless Ink Tank Printer with Auto Duplex, ADF, and Refillable Ink System MECH-03 Error Fix: Ink Tank Low or Empty

Error code MECH-03 on the HP HP Smart Tank 7001 All-in-One Wireless Ink Tank Printer with Auto Duplex, ADF, and Refillable Ink System means: Ink Tank Low or Empty. One or more refillable ink tanks need to be refilled with HP ink bottles — the Smart Tank 7001 uses HP GT53 or GT53XL (black) and HP GT52 (cyan, magenta, yellow) ink bottles; to refill, open the ink tank access area, open the color-coded cap on the correct tank, and insert the bottle — the ink flows automatically and stops when the tank is full; do not overfill past the MAX line; never mix different ink brands or generations; ink level indicators on the printer show approximate levels through transparent tank windows
