Thank you for this guide! My printer scan head was clicking and grinding at startup and would not allow me to print.

In addition to cleaning the glass and calibration strip, I manually slid the scanner head back and forth through its full range of motion. Once the printer was reassembled, the grinding ceased and all operations are back to normal.
