A print head can collect toner and contamination during use in an image forming device. A Customer Replaceable Unit (CRU) moves across the face of the print head when withdrawn. A cleaning unit, which can be a silicone blade, foam pad or other suitable material, is attached or integral to the CRU such that when the CRU is withdrawn the cleaning unit wipes the surface of the print head. Insertion of the original CRU or a new CRU would again wiped the cleaning unit over the lens surface providing the required cleaning action. Accordingly, this cleaning operation happens automatically when the CRU is replaced, and also the CRU can be pulled out and re-inserted to perform the cleaning operation if contamination is detected or at other maintenance points.
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.
