| Number | Title | Issue Date |
| 7102102 | Heater assembly including thermal fuse A heater assembly heats media substrate in a printing system prior to imprinting a desired image on the substrate. A plate member engages the substrate and communicates thermal energy thereto for the heating. A laminar assembly is adhered to the plate member and inc... | 09/05/2006 |
| 5504562 | Electrostatographic reproduction machine having a platen cooling cover An electrostatographic reproduction machine including a cover assembly for holding an original document onto a glass platen, and for dissipating heat build up from the top of the glass platen. The cover assembly includes a heat conductive white film layer... | 04/02/1996 |
| 5243386 | Optical system housing structure for image forming apparatus An image forming apparatus such as an electrophotographic copying machine includes an optical system for housing a scanning exposure optical system. The optical system housing has air inlet and outlet holes for introducing air into and discharging air fro... | 09/07/1993 |
| 5162855 | Image forming apparatus having temperature sensor for estimating the off time of the fuser as related to the platen glass temperature A copying machine for reproducing an image with toner on a recording sheet. The copying machine has a photoreceptor to hold a latent image corresponding to the image on its surface, in which the surface is charged to a predetermined electric potential bef... | 11/10/1992 |
| 5109253 | Copier technique for determining speed and threshold number of sheets for a copier A copying apparatus is adapted to suppress the temperature rise of a platen glass by decreasing the copy speed from a first speed to a second speed after the apparatus has copied a threshold number of sheets in succession. The above parameters of the firs... | 04/28/1992 |
| 4827283 | Lighting control method and a lighting control apparatus of a light source in an image forming apparatus A lighting control method and an apparatus thereof which determine during the returning motion of the light source, whether the next paper is fed to the registration roller, and if it is determined that the paper is fed, the light source is caused to turn... | 05/02/1989 |
| 4695151 | Image forming apparatus In an image forming apparatus, an original placed on an exposure table is illuminated for exposure to form an image. The image forming apparatus comprises an optical unit including a light source for exposing the original and a ventilating unit for ventil... | 09/22/1987 |
| 4684237 | Scan assembly moved between alternate positions to prevent platen overheating A scanning system for an electrophotographic printing machine is adapted to alleviate the problem of platen overheating when the machine is operated in a mode wherein documents are stream-fed past an exposure zone formed by a stationary scan/illumination ... | 08/04/1987 |
| 4297024 | Exposure device of an electrographic copying apparatus An exposure device of an electrographic copying apparatus including at least one heat generative exposure lamp for exposing a photosensitive paper corresponding to an original to be copied. A paper detector detects the photosensitive paper at an inlet of ... | 10/27/1981 |
| 4214832 | Electrostatic copying machine comprising improved document scanning means A book type document is placed on a glass platen face down and scanned by a reciprocating optical system one or more times to produce one or more copies respectively. A retractable conveyor comprising an endless belt is moved onto the platen to automatica... | 07/29/1980 |
| 4183656 | Slit exposure type copying apparatus The operation of a slit exposure type copying apparatus is controlled to avoid overheating of a transparent cover for the original supporting station by controlling either, or both, of the excitation of the exposure lamp and the return movement of the mov... | 01/15/1980 |
| 4098552 | Copying machine A copying apparatus with a reciprocating platen is disclosed having an improved illumination system. The system includes a regulator that maintains an illumination source at an optimum value by turning the illumination source on during forward scan of the... | 07/04/1978 |
