Checks
1 Does the oil case have an adequate
amount of fixing oil?

Is the hose from the oil case to the
upper oil pan clogged with dust?
3 Is the fixing oil level sensor (PS6)
normal? (Check as when checking a
photointerrupter.)
4 Operate the oil pump drive solenoid
using 'IO' of 'FMISC' under 'FUNC' in
service mode. Does it operate
normally?

'FMISC' under 'FUNC' in service
mode. At this time, does the voltage
between J2209A-3 and J2209A-4 on
the DC controller PCB change from
24 V to 0 V?
