HP HP Smart Tank 7001 All-in-One Wireless Ink Tank Printer with Auto Duplex, ADF, and Refillable Ink System MECH-07 Error Fix: Print Quality Degradation

Error code MECH-07 on the HP HP Smart Tank 7001 All-in-One Wireless Ink Tank Printer with Auto Duplex, ADF, and Refillable Ink System means: Print Quality Degradation.
