Symptom Corrected Version
Sometimes, the transfer belt sensor incorrectly declares a “no paper”
condition when it detects a high-density solid image, even if there is paper at
the sensor.
The leading edge is dirty with toner. To improve this, the ITB cleaning time
(ON time for the cleaning brush) was increased.
The default for the following SP modes (image transfer current) was
changed. This is to prevent residual images on small paper types.

Note: In addition to this BICU version, be sure to update the main unit
controller firmware to V1.04 or later.
V1.03
A new SP mode was added to turn on the development fan at job end
(default: the fan is turned Off at job end). This is to prevent dirty background,
which can occur in high-temperature/high-humidity conditions.
