"Error says paper jam, but there is not. What could cause this?"에 답변Hello Kathy, Your printer makes a "grinding sound". This is usually due to two things: 1. A dirty printhead rail. It is either ink residue or dry. Try gently cleaning it with some water. 2. Paper pick up roller(s) not picking up. Clean them with a damp terry cloth towel or a multi-purpose cleaner. Good Luck!
