Chapter 5 5.3 Start-Up Sequence 5.3.1 Overview The system software used to control the operation of the machine is stored on the HDD. When the machine is started up, the CPU on the main controller PCB reads the system software from the HDD into the image memory (DDR-SDRAM) of the main controller PCB for use as instructed by the boot program of the boot ROM.
Page 136 Chapter 5 -Control Program 2 (interval 3) 1. The individual software modules are initialized, and the printer and screen configurations are established. 2. The start-up sequence ends when the printer and scanner are correctly recognized. Otherwise, an error code (E732/E733) will be indicated at the end of a connection time-out. The engine becomes ready to accept a job when the start-up sequence ends normally.

Chapter 11 11.2.5 Checking Life 11.2.5.1 Lifetime Detection of Fixing Assembly Belt Unit The lifetime of the fixing assembly is estimated by the following three values. When the following three values reach their thresholds, message and E008-0001 are displayed. The main cause of reducing the lifetime is torque increase of the fixing drive motor. It is mainly because the message is displayed by reading the current (torque) running through the fixing drive motor.

Page 571: Periodically Replaced Parts
Chapter 15 15.1 Periodically Replaced Parts 15.1.1 Periodically Replaced Parts Some parts of the machine must be periodically replaced to ensure a specific level of product performance (i.e., they may not show wear but can significantly affect the machine performance once they fail). If possible, schedule any periodical replacement so that it coincides with scheduled servicing.
Page 572: Durables And Consumables
Chapter 15 15.2 Durables and Consumables 15.2.1 Outline Some parts of the machine may require replacement once or more over the life of the product because of deterioration or damage. Replace them as needed by referring to the guide. Find Out When to Replace Use the following service mode to find out when it is best to replace a specific durable part.
