4. NEW PRE-TRANSFER LAMP:
A new pre-transfer lamp (PTL) has been added to the B070/B071 enhanced models. The PTL has been
added to aid in poor drum separation problems, but if the PTL is used a blurred image may appear on the
leading edge of the paper. Therefore, the default setting for the PTL is set to "Off."
The following service programs have been added for the new pre-transfer lamp.
