Abstract
In large-format printers, it is common practice to begin printing without engaging the Take-up reel to minimize material waste, known as print from the leading edge.
However, this approach introduces a significant risk: as the printed substrate advances, it eventually touches the floor. Contact with the floor can lead to media lifting into the print zone, causing severe carriage crashes and operational downtime.
To mitigate this risk, the invention proposes an automated alert system that notifies the operator when the substrate’s edge is approaching the floor. The system combines an audible signal (beep), a visual indicator (specific beacon color or blinking pattern), and optionally a remote notification via any remote solution.
This timely alert enables the operator to attach the media to the Take-up reel before it reaches the floor, thereby preventing crashes and improving workflow efficiency.
