HP HP Smart Tank 7001 All-in-One Wireless Ink Tank Printer with Auto Duplex, ADF, and Refillable Ink System MECH-10 Error Fix: Ink System Air Lock

Error code MECH-10 on the HP HP Smart Tank 7001 All-in-One Wireless Ink Tank Printer with Auto Duplex, ADF, and Refillable Ink System means: Ink System Air Lock. Air entered the ink supply lines causing inconsistent ink delivery — air can enter when ink tanks run completely empty, after moving/shipping the printer, or after printhead replacement; run the printhead cleaning utility 3-5 times with short pauses between runs to purge air from the lines; fill all tanks to the MAX line before starting the purge process; gently tilting the printer can help free trapped air bubbles; an air lock that cannot be cleared by repeated cleaning may require professional service to re-prime the ink system
