SC544 or 564 appears mistakenly
Prepared
by:

Tier 2
SYMPTOM
SC544 (Heating roller thermistor (center) error 3) or SC564 (Heating roller non-contact
thermistor error 3)
may
appear mistakenly while the lower drawer unit is out. This
symptom occurs only in limited lots of the D014/D015 copier. See the defective lot number
table attached to this RTB. (Even for the defective lot numbers, this symptom will
NOT

appear 100%)
NOTE:
While the lower drawer unit is out, electrical power for the fusing unit is disconnected.
Therefore, SC544 or SC564 should not appear actually. However, these SC
may
appear
mistakenly. Because the fusing unit has no power, this incorrect SC544 or SC564 is not
the actual thermistor error.
CAUSE
For the defective lot machines, the detection margin of SC544 and SC564 in the power
supply unit is a little bit small compared with the design target. Therefore, the incorrect
SC544 or SC564
may
appear even though the electrical power for the fusing unit is
disconnected.
SOLUTION
For the defective lot machines, upgrade the Engine firmware to the following version or
newer at the machine installation or the next service visit.
Firmware type: Engine
Version: 1.07:01 or newer.
Program No.: D0145402G or newer.
After the December 2008 production, this version or newer has already been applied.
