The magnitude and polarity of the voltage on the fuser roll surface is controlled by either electronic charge application means or by applying charge control agents to the fuser. For negative toner, the fuser roll voltage must also be negative (and visa versa). This will repel the negative toner at the entrance to the fuser nip, prevent the toner from transferring to the fuser roll at the entrance of the fuser nip and preclude the formation of NVO and consequently prevent MOC.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
