Chapter 1 1.2.4.3 Handling of the Laser Assembly 0010-7424 Take full care when servicing the area around the laser scanner system, as by avoiding bringing a reflective tool (e.g., screwdriver) into the laser path and removing watches and rings before starting the work. (These items are likely to reflect the laser light, and exposure to laser light can permanently damage the eye.) The machine uses red laser light, and its covers that possibly reflect the light are identified by an appro- priate label.

Chapter 4 4.3 Start-Up Sequence 4.3.1 Overview 0010-7846 The system software that controls the machine is stored on its HDD. When the main power is turned on, the CPU on the main controller PCB loads the system software from the HDD to the work memory (DDR-SDRAM) of the main controller PCB according to the instructions of the boot program stored in the boot ROM.
Page 99 Chapter 4 <Boot Program Area> - Boot Program (interval 1) When the main power switch is turned on, the CPU on the main controller PCB runs a self-diagnostic pro- gram. The machine checks the condition of the image memory (DDR-SDRAM) and the HDD, indicating an error code upon detection of a fault.
