Use in a normal way.
In a normal boot sequence, [Normal
boot diag] is executed to omit the
device (ESS) diagnosis items and
reduce the start-up time. On the other
hand, [Long boot diag] is executed
for more detailed diagnosis of the
device. The diagnosis items and the
differences are as follows:
• RAM diagnosis:
Write/Read/Verify test is
executed for the entire area.
• Program ROM diagnosis:
The checksum is calculated to
check the ROM and necessary
actions are taken.
• Font ROM diagnosis:
The checksum is calculated to
check the ROM and necessary
actions are taken.
Initialize the configuration area
(printer setting value, etc.) of NVRAM

If any error occurs when spooling in
HDD and the system does not start
up even though turning OFF/ON the
power supply, erase the spool area in
HDD and start up the system. Then,
initialize the NVRAM (ESS)
configuration area (printer setting
value, etc.) too. (Job Log is not
erased.)
