General Procedures & Information
Initial Issue
GP 14 Special Boot Modes
Purpose
This procedure describes methods of recovering from certain unclearable faults.
Procedure
Some boot-up failures, as well as some un-clearable fault codes, may be caused by software
corruption, or by structural flaws in a command sent to the machine. In these cases, it is some-
times possible to bypass or delete the offending code during the startup process.
CAUTION
There are four special boot modes. Each mode performs a different set of initializations to
bypass a specific set of problems. There is information lost in each procedure, thus, they
should not be used unless specific directions are given. The following list gives these proce-
dures, in the order from least-invasive to most-invasive. If you are instructed to perform a spe-
cific initialization, perform only that procedure. If you are asked to perform the entire series,
perform the steps in the order given, until the problem is resolved.
Job Log Clear Mode
This step will delete any print or copy job that is in process, and then perform a reboot.
To execute: With the machine completely powered off (both the Power Switch and the Main
Power Switch in the OFF positions), simultaneously press and hold the 1, the Stop, and the
Energy Saver buttons on the Control Panel, and then switch on the Main Power Switch and
then the Power Switch. Continue to hold down the 1, Stop, and Energy Saver buttons while
switching on the power. Hold the buttons down until the boot up screen (progress bar) appears.
HDD Initialize Mode
This step will delete all pending print or copy jobs in the IOT job queue, initialize the IOT HDD,
and then perform a reboot.
CAUTION
All customer data on the HDD (customer’s files/configuration such as mailboxes, scanned doc-
uments, user IDs and account IDs for accounting) will be deleted.
To execute: With the machine completely powered off (both the Power Switch and the Main
Power Switch in the OFF positions), simultaneously press and hold the 6, the Stop, and the
Energy Saver buttons on the Control Panel, and then switch on the Main Power Switch and
then the Power Switch. Continue to hold down the 6, Stop, and Energy Saver buttons until the
boot up screen (progress bar) appears.
HDD Format Mode
This step will delete all pending print or copy jobs in the IOT job queue, format the IOT HDD,
and then perform a reboot.
CAUTION
All customer data on the HDD (customer’s files/configuration such as mailboxes, scanned doc-
uments, user IDs and account IDs for accounting) will be deleted.
To execute: With the machine completely powered off (both the Power Switch and the Main
Power Switch in the OFF positions), simultaneously press and hold the 4, the Stop, and the
Energy Saver buttons on the Control Panel, and then switch on the Main Power Switch and
then the Power Switch. Continue to hold down the 4, Stop, and Energy Saver buttons until the
boot up screen (progress bar) appears.
NVRAM Init Mode
CAUTION
STOP HERE! This portion of the routine will set all IOT ESS NVM values to default. DO NOT
execute this step unless specifically directed to perform this portion.
Do not attempt this part of the procedure unless there is a known-good Machine Settings
floppy, an accurate Configuration Report and/or other data that will enable you to reload the
correct NVM values for this machine.
This step will initialize the IOT ESS NVM (SYS-System and SYS-User) and then reboot the
machine to the Initialize Wizard. Follow the on-screen instructions when the Initialize Wizard
displays.
To execute: With the machine completely powered off (both the Power Switch and the Main
Power Switch in the OFF positions), simultaneously press and hold the 3, the Stop, and the
Energy Saver buttons on the Control Panel, and then switch on the Main Power Switch and
then the Power Switch. Continue to hold down the 3, Stop, and Energy Saver buttons while
switching on the power. Hold the buttons down until the boot up screen (progress bar) appears.
