HP HP Color LaserJet Pro M255dw Wireless Color Laser Printer with Auto Duplex Printing and 22 ppm MECH-02 Error Fix: Color Registration Misalignment

Error code MECH-02 on the HP HP Color LaserJet Pro M255dw Wireless Color Laser Printer with Auto Duplex Printing and 22 ppm means: Color Registration Misalignment. Colors on printed output are misregistered, causing blurry edges, offset colors, or rainbow-fringe effects on black text — the M255dw should automatically run a color calibration at regular intervals; run a manual calibration from Setup > System Setup > Print Quality > Calibrate Color on the LCD; if registration is still poor, the imaging drums or intermediate transfer belt (ITB) may be worn or the registration sensors are contaminated
