Checks
1 Is there a fault on the fixing roller
(upper, lower), fixing oil applying
roller, or the drive assembly of the
feeding assembly? Or, is any of them
subjected to excess load?
2 Set the meter to the 12VDC range.
Does the voltage between J2213A-6
(+; M9D*) and J2213A-7 (–; GND) on
the DC controller PCB change from 5
V to 0 V after the power has been
turned on, WMUP has ended, and
INTR begins (i.e., when the tempera-
ture of the fixing roller reaches
110°C)?
