1 Improper adjust-
ment
or assembly
of the JOG dial JOG Assy Check that the load value for the JOG dial
is within the specified range, referring to
“Measuring method” in “
8 .3 JOG DIAL
ROTATIO N LOAD ADJUSTME N T.”
If it is outside the specified range, adjust the position
of the Adjust Plate to change the load value for the
JOG dial, referring to “How to Adjust” in “
8 .3 JOG DIAL
ROTATIO N LOAD ADJUSTME N T.”
—————
During the above adjustment, if the upper-limit
adjustment position of the Adjust Plate is reached,
oil mayhave been spattered on the Adjust Plate.
Replace the washer, gear, and cam plate with new
ones, then reassemble. After replacement, adjust
the position of the Adjust Plate to change the load
value for the JOG dial. —————
The JOG dial turns too freely. (The load value for the JOG dial is outside the specified range.)
1 Improper adjust-
ment of the JOG
dial or defective
washer, gear, or
cam plate JOG Assy Check that the load value for the JOG dial
is within the specified range, referring to
“Measuring method” in “
8 .3 JOG DIAL
ROTATIO N LOAD ADJUSTME N T.”
If it is outside the specified range, adjust the position
of the Adjust Plate to change the load value for the
JOG dial, referring to “How to Adjust” in “
8 .3 JOG DIAL
ROTATIO N LOAD ADJUSTME N T.”
—————
During the above adjustment, if the lower-limit
adjustment position of the Adjust Plate is reached,
shavings from the worn-out washer may have
increased the friction. Replace the washer, gear,
and cam plate with new ones, then reassemble.
After replacement, adjust the position of the Adjust
Plate to change the load value for the JOG dial. —————
Resistance to turning the JOG dial is too strong. (The load value for the JOG dial is outside the specified range.)
1 Improper adjust-
ment
or assembly
of the JOG dial JOG Assy Check if the plate spring of the JOG
holder is worn out or deformed. Replace the JOG holder. After replacement,
adjust the position of the Adjust Plate to
change the load value for the JOG dial. —————
Check if there is any foreign object in
the link section (gears). Remove the foreign object. During reassembly,
pay attention to the position of the cam plate.
After replacement, adjust the position of the Adjust
Plate to change the load value for the JOG dial. —————
1 Loose connections
in the communi-
cation line. Between USBA Assy
and MAI
N Assy
Check the connection of the USB
communication line. If connection is improper, resolder it.
If connection is proper, go to 2. —————
4 Defective
MAI
N CPU
MAI N Assy If the symptom persists after the above
corrections. The MAI N CPU (IC10) is defective.
Replace the MAI N Assy.
—————
2 Defective
MAI
N CPU
MAI N Assy Check the signal from the MAI N CPU and
USB CO N TROLLER.
If the signal is not output from the MAI N CPU
(IC10), it may be defective.
Replace the MAI
N Assy.
—————
3 The USB
POWER SW IC
or its control
signal is defective. USBB Assy Check the CPU_USB_HSTPWRE N and
CPU_USB_HSTPWRFL signals from the
USB POWER SW IC (IC6301).
If the CPU_USB_HSTPWRE N signal does not become H,
check the connection. If the connection is OK, then the
MAI
N CPU (IC10) is defective. Replace the MAI N Assy.
If the CPU_USB_HSTPWRFL signal does not become H,
the USB POWER SW IC (IC6301) is in a state of
shutdown caused by abnormally high temperature.
Check the connection. If the connection is OK, then the
port may be damaged. Replace it.
—————
2 V +5_USB_HOST_
V BUS is defective.
MAI N Assy Check V +5_USB_HOST_ V BUS of the
USB power supply.
If V +5_USB_HOST_ V BUS cannot be confirmed, go to 3.
If V +5_USB_HOST_ V BUS can be confirmed, go to 4.

[4-1] N o communication via the USB connector (Type A)
Check the following, with a USB device connected to the USB A connector.
1 Loose connections
in the communi-
cation line. MAI N Assy Check the connections from the MAI N
CPU and USB CO N TROLLER.
If connection is improper, resolder it.
If connection is proper, go to 2. —————
3 Loose connections
in the USB signal. MAI N Assy Check the connections of the
communication line (USB_D+, USB_D-). The communication line may be loosely
