Chapter 4 - Troubleshooting and Maintaining the Printer 9 Check mark detection: a Lift the printhead. b Slowly pull out the media. When the LSS detects a black mark, the cursor moves to the left. LSS AUTO 10 If the LSS does not move as described in Steps 8 and 9, make sure that: • the cursor position is accurate. Refresh the cursor position by pressing the D key. • the LSS is laterally aligned with the slots or black marks. • both the upper and lower parts of the LSS are aligned with each other. • the transfer ribbon is properly loaded so it does not interfere with the LSS. For help, see "Loading Ribbon" on page 43. • the LSS guides are clean and free from stuck labels or other objects that may interfere with the light that goes from one part of the LSS to the other. For help, see "Cleaning the Printer" on page 125. • the media does not have some kind of preprint that may disturb detection. • there is enough difference between the black marks and the surrounding areas. • the liner is transparent enough. • the LSS works properly with another type of media. 122 PX4i and PX6i High Performance Printer User's Manual
