Details:
TDCU Motor lock signal criteria:
 Drum motor
High if the motor speed is not within the range of target
value ± 6.25%.
Low if the motor speed is within the range of target value ±
6.25%.
 ITB drive motor, PTR Motor
High if the motor speed is not within the range of target
value ± 6.25%.

6.25%.
Target value:
If the default motor speed was adjusted using the SP, the
adjusted value is used as the target value.
Specification:
 When the motor is on, each lock signal is checked every
100 milliseconds. If the High status is detected 20 times

running correctly. The machine issues an SC and stops the
motor.
 Motor defective, connector disconnected, harness broken,

SC587-00Y Development Temperature Detection ErrorTemperature Sensor Output Error: 0.35V or lower (100 degrees
centigrade or higher) or 3.07V or higher (-30 degrees centigrade
or lower).
Details:
In case of a Temperature Sensor Output Error: 0.35V or lower
(100 degrees centigrade or higher) or 3.07V or higher (-30
degrees centigrade or lower), the machine determines the
sensor is malfunctioning and assumes that the temperature is
100 degrees centigrade.
If the sensor is determined as malfunctioning 3 times
consecutively (3 outputs, each of which is an average of 6
readings), the machine issues the SC and no longer use the
sensor, using the assumed temperature "100 degrees
centigrade" instead.
However, the sensor is used again after power off/on.
 Connecter disconnected or harness broken
 Sensor defective
 Connecter disconnected or harness broken: Revert

port on the BCU.
 Abnormal condition (Connector not connected): "L" at the
HORUS port on the BCU.

SC925-00NetFile function error
SC925-01NetFile function errorThe NetFile file management on the HDD cannot be used, or a
NetFile management file is corrupted and operation cannot
continue.
 HDD defective
 HDD inconsistency caused by power failure during HDD
access, etc.
 Software bugIf another SC related to HDD errors (SC860 to SC865) is issued
at the same time, the HDD is the cause. Solve the other SC.
 If SC860 to SC865 is not issued
 Turn the main power off/on.
 If this does not work, initialize the HDD NetFile partition
(SP5-832-011). Approval by the customer is required
because received fax message waiting to be delivered and
documents waiting to be captured will be lost.
Procedure:
Go into the User Tools mode and do "Delivery Settings" to print

 If this does not solve the problem, initialize all partitions of
the HDD (SP5-832-001), then turn the machine power off
and on.
Approval by the customer is required because documents
and Address Book information in the HDD will be lost.
Received fax messages stored are protected but the order
may be changed.
 If this does not solve the problem, replace the HDD.
