The CSF/CSD will not be able to bypass the HSC carton/totes unless:

 - it is a unique size carton
 - it must be completely filled similar to a closed box.

The light curtain sensor will measure the height up to the major flaps, and the bypass sensor reading straight into the carton.

Please see the illustration below as you are looking at the box from the entrance to the exit of the machine.

The red line is where the light curtain will read on the major flaps.
The blue line is where the bypass sensor will read depends on how full you are filling the box.
Only if the distance (D) between the red and blue line is zero, the machine will be in bypass mode.

There are two ways we can make a HSC box or tote work.

1. Ensure that the HSC is filled to the top edge of the box so that it registers as a "closed box" when detected by the bypass sensor.
   
   For products of irregular shapes, place a flat object on top of the box so that the bypass sensor registers it as fully closed.

2. The size of this HSC must be unique in terms of width and height. It means that the width and the combined box and major flaps height of any RSC cannot match the width and height of the HSC.

    • That way we can add that into the program to bypass a certain box size.

    • If a RSC box somehow share the same characteristic (width, combined box and major flap height) as
       the HSC box height, that RSC box will get bypassed.

Bypass on a CSF/CSD is different from a CSEG bypass. CSF/CSD does not have a cylinder to drop down the bottom tape head. Therefore, bypass on a CSF/CSD machine will still seal the bottom as it passes through the tape head, and only bypass the top flap folding and top seal.
