Using the Boot-Up Sequence to Troubleshoot

When you Power On the Printer, the Printer performs the Boot-Up sequence which initializes the major components of the Printer. If for some reason the Boot-Up sequence fails because a component has failed to initialize, the following explanations will help you to locate the failing component:

During the first phase of the Boot-up sequence (all the squares turn grey) the Printer is initializing the Operating System. If for some reason this sequence fails, try the following:

1Switch the Printer Off and wait a few minutes. Switch the Printer On again and check if the initialization sequence is successful.

2If the initialization sequence fails again, replace the Electronics Module ⇒ Page 8-24.

During the second phase of the Boot-up sequence (all the squares turn black) the Printer is initializing various components (too numerous to mention). In normal circumstances, if a component fails during this sequence a System Error will appear and you should refer to Chapter 2 - System Error Codes. The following information explains what is being initialized as each square turns black:

Initializing various components of the Main PCA.
