HP OfficeJet Pro 8025e Wireless All-in-One Printer with 20 ppm, Smart Tasks, and Mobile Fax MECH-09 Error Fix: Fax Line Connection Problem

Error code MECH-09 on the HP OfficeJet Pro 8025e Wireless All-in-One Printer with 20 ppm, Smart Tasks, and Mobile Fax means: Fax Line Connection Problem. Fax cannot connect due to phone line issues — verify the phone cable is connected to the LINE port (not EXT) on the printer; ensure the phone service is active by testing with a handset; digital phone services (VoIP, cable, fiber) often do not support fax well — an analog adapter or dedicated analog fax line may be required; do not use DSL line filters between the wall jack and the printer (use a direct connection to the DSL splitter)
