The surface of the glue in the vat did not reach the lower limit position. This error
occurred when the glue surface was detected below the lower limit position 4
times in succession during the glue replenishment cycle.
The glue level thermistor could not detect the glue surface at the upper limit
position: 1) After glue was detected above the low limit mark, and 2) After 12
glue packets were supplied, and 3) No glue had been recently applied.

thermistor:
1. Glue level thermistor 1 value (low limit) was out of the range: 128°C±14C
2. Glue level thermistor 2 value (high limit) was out of the range: 142°C±10C
3. Glue level thermistor adjustment value 1 was larger than for adjustment 1.

current exceeds 500 mA.
When a toner supply bottle motor is on, it is checked every 100
milliseconds for lock signals. The following steps are executed
every second.
If the lock signal was detected 9 times in 10 samplings, the
lock counter increases by one. When the lock counter value
is 23 or larger, the SC is issued.
If the lock signal was detected 8 times or less in 10
samplings, the lock counter is cleared.

bottle replacement etc.), the lock counter value is kept as is.
Sampling starts again the next time the motor runs.

(also when the machine enters sleep mode, in which the
plotter is turned off) or when an SC is issued.

Y Development Temperature Detection Error
Temperature Sensor Output Error: 0.35V or lower (100 degrees

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.

FFC set detection (Error between IPU and BCU)
The HORUS port on the BCU is used for FFC connection
detection to detect FFC (harness) disconnection and loose
connection between BCU and IPU. By checking the "H" or "L"
status of this port, the connection status can be checked.
Normal condition (Connector connected): "H" at the HORUS
port on the BCU.
Abnormal condition (Connector not connected): "L" at the
HORUS port on the BCU.
Details:
When a connector is disconnected, the voltage level
becomes "L" level (0V level) because there is a pull-down
resistor in the BCU.

disconnected, the number of parallelly connected resistors
changes and therefore the voltage input to the AD terminal
changes.

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
