Abstract: Printer job recovery for use in an electronic reprographic system includes the detection of faults affecting printer operation. If such a fault is detected, fault recovery is effected and operation continues. It is then determined whether the jobs are incomplete. If not, recovery is skipped and normal operation continues. If, however, it is determined that there are incomplete jobs, it is then determined whether there are any partially complete jobs. If not, normal system operation continues. Upon determination that there are partially complete jobs, the system recovers the oldest partially complete job. It is again determined whether there are any partially complete jobs. The cycle continues until it is determined that there are no partially complete jobs.

Abstract: An electrophotographic printing machine is provided with a photoreceptor drum (1) including a transparent cylindrical base having a transparent electrically conductive layer (1b) and a photoconductive layer (1c) laminated in this order on a surface thereof and a dielectric belt (8) in contact with the photoconductive layer (1c). The photosensitive layer (1c) is exposed while voltage is being applied across an electrically conductive toner (T) and said transparent electrically conductive layer (1b), thereby forming a toner image on the photosensitive layer. After the toner image on the photosensitive layer is transferred to the dielectric belt (8) which temporarily carries the toner image, the copying material (P) is superimposed on the toner image, and heat and pressure are applied to the toner image respectively from a heater (10) and a pressurizing roller (12). Since the melted toner is transferred onto the copying material using the adherence of the transfer sheet without using electric Coulomb force, the efficiency in transferring the toner image to the copying material is not affected by the electric surface resistance of the copying material. An image can therefore be formed using the electrically conductive toner even on a copying material of low electric surface resistance such as a normal transfer sheet.

Abstract: A spectrometric instrument which exhibits an intrinsic profile for a sharp spectral line produces profile data for narrow spectral lines. The spectral lines are effected with a high finesse etalon of gold coated polymer. A transformation filter is computed for transforming the profile data to a gaussian profile. A wavelength calibration is combined with the filter to effect a correction matrix which is applied to sample data to generate calibrated standardized data. Iteratively a correction matrix is applied to calibration data to generate standardized calibration data which is utilized for the wavelength calibration. Calibration is effected with an optical standard, an interference etalon and a fringe formula. Etalon effective thickness is first estimated and then precisely determined so that fringe peaks calibrate wavelength.
