Identifying the Problem

3. If there is a line, it appears along the entire length of the image, from head to tail.

Implementing a Workaround Until the Head is Replaced

2. Run the bbs balance script, so you to see which pixel is causing the beam balance to fail.
3. Run the bbs profile script.
4. Chop the extra pixel.
   Note: Make sure to order and replace the head as soon as possible.

Sending the Head for Repair

1. Drain the collent from the head.
