2. Symptom:
Control PWB units for mid-August and mid-September 2011 production, can exhibit
unstable output power voltage if the voltage dropped under the limit required for
the operation of CPU at power-off.
As a result, the paper tray lifts up erroneously and the tray rotating plate is elevated
above the specified position. Eventually a paper jam may occur at Tray 3 or 4.
According to T/R No. CCE-970, a modification has been implemented to the control PWB
unit. Since a low voltage detection circuit has been embedded to the control PWB unit
with this modification, the symptom described above does not occur.
3. Description:
If the symptom described above has been reported from field, please replace with new
Control PWB unit.
