Print quality issues. Run "Clean Printhead" from the OfficeJet's Tools menu — use the standard clean first, then a Level 2 clean if needed.
Fax setup issues. Confirm a working RJ-11 phone line is connected to the 1-LINE port and the fax country/region is set correctly.
Wi-Fi setup issues. The OfficeJet Pro 8620 supports 2.4 GHz Wi-Fi and Ethernet — use HP Smart or the printer's wireless setup wizard.
