During certain uncommon tasks such as the removal of a paper jam, it is possible to inadvertently touch a lubricated area on the printer's chassis causing a small amount of grease to be deposited onto the timing strip. Grease on the timing strip may result in poor print quality including; mis-aligned or distorted characters, vertical lines or, in some cases, an inoperable error condition or knocking / grinding noise.
To connect the printer to your network, Advanced Setup method will have you manually enter the access point (network name) and network key (password / passphrase). For office use, consult your network administrator. Take added care when connecting to a network that is not protected with security measures, as there is a risk of disclosing data such as your personal information to a third party. REFERENCE:
