HP HP Smart Tank 7001 All-in-One Wireless Ink Tank Printer with Auto Duplex, ADF, and Refillable Ink System MECH-02 Error Fix: Ink Not Flowing from Tank to Printhead

Error code MECH-02 on the HP HP Smart Tank 7001 All-in-One Wireless Ink Tank Printer with Auto Duplex, ADF, and Refillable Ink System means: Ink Not Flowing from Tank to Printhead. One or more colors are not printing despite the ink tank showing adequate ink level — air bubbles or a blockage in the ink supply tube between the tank and printhead prevents ink delivery; run printhead cleaning 3-4 times to force ink through the system; ensure the ink tanks have sufficient ink (very low levels can allow air into the lines); gently tilt the printer 45 degrees left and right a few times to help dislodge air bubbles; if the blockage persists, the ink supply system may need professional service
