Function / [Setting]
Press Start to detect defective sectors on the hard disk.
Before shipment, the original defective sector information is
stored in the non-volatile memory. This information allows
the hard disk to avoid accessing the defective sectors. If
other sectors become defective after shipment, this sector
information must also be stored in non-volatile memory, to
prevent output of abnormal images. During media checks,
new defective sector information is stored in the IPU non-
volatile memory. This information allows the IPU to avoid
accessing the bad sectors. As check processing proceeds,
the progress is indicated by the displayed numbers (0 ~
100). Time required for execution depends on the hardware
specifications.
Press Start to format the hard disk.
Required time for execution depends on hardware
specifications. If defective sectors are not found, check
SP4960-001, 002. If a defective sector is found, some extra
time is required for sector substitution.
Press Off or On to switch the hard disk off and on.
The hard disk should stop operating whenever possible to
prevent noise and to protect the hard disk. However, if the
hard disk is not operating, the fast copy speed may slow
down, waiting for the hard disk to start.
Press Start to clear the bad sector from the NVRAM.
Perform this setting after removing a defective disk and
replacing it with a new disk.
Displays the number of defective sectors on the hard disk.
The number is based on the defective sector information
that the IPU has created during operation. When the
number reaches 51, SC361 is displayed, then format the
hard disk with SP4960 001, 002.
Displays the hard disk model name (40 characters) on the
touch-panel display.
Press the button for Ultra DMA or Multi Word DMA
Press On or Off to enable or disable hard disk detection.
Set to Off to disable a defective hard disk if either hard disk
malfunctions, so the customer can continue to use the
copier functions while waiting for a replacement disk.
Adjusts the synchro-cut position.
[-9.9 ~ +9.9 / 0.0 / 0.1 mm/step]
Use the 210-mm position in the sample to check the
difference. This difference is used to calculate the motor
clock count for adjusting the difference.
Adjusts the synchro-cut position.
[-9.9 ~ +9.9 / 0.0 / 0.1 mm/step]
Use the 1000-mm position in the sample to check the
difference. This difference is used to calculate the motor
clock count for adjusting the difference.
