14.1.1 BEZEL / PAPER EXIT / LED CONTROL
The additional circuit boards contain the paper exit sensor Sharp GP2S700 and the bezel lighting. 6 LEDs (GPT-4672) or 8
LEDs (GPT-4673) will be controlled via a LDO with enable input. The current supply is provided by the 24 V printers power
supply and is secured via fuse F6 (placed on the printer controller board). The LDO output voltage is set to 9.8 V for GPT-
4672 and 15.6 V for GPT-4673.
