920.11—POST—Two toner sensors not connected error service check
Step Questions / actions Yes No
1 Remove the left cover. See “Left cover
removal” on page 4-23. Check all toner level
sensor cables connected to the rear of the
HVPS.
Are any of the cables damaged?
If only one toner level
sensor is damaged:
• Disconnect the sensor.
• Go to step 2.
If two toner level sensors
are damaged, replace the
damaged sensors. See
“Toner level sensor
removal” on page 4-174.
Go to step 2.
2
Disconnect one of the toner level sensors,
and POR the printer. See “Toner level
sensor removal” on page 4-174.
Does the 920.11 error occur again?
If the error recurs, then this
sensor is one of the bad
sensors. Continue
disconnecting the toner
level sensors until two
sensors are disconnected
and the 920.11 error
occurs.
Replace the toner level
sensors that are
disconnected. See “Toner
level sensor removal” on
page 4-174.
Repeat this step for the
other toner level sensors
until the 920.11.
