1. Set paper sensor threshold: white paper has relatively smaller sensor brightness while black paper has
relatively bigger sensor brightness. When sensor brightness is bigger than paper sensor threshold, printer
could detect black mark. Otherwise, printer could not detect black mark. In latter case, users have to lower
paper sensor threshold. For example, when printer stops in the middle of white paper, users could increase
the paper sensor threshold. The recommended value is between 75% ~ 95%.
2. Close lid and press paper feed. The paper should stop with the bottom of the form at the tear bar.
