Abstract

The present disclosure relates to magnetic xerographic imaging and in particular, relates to a system architecture for providing simplex and/or duplex magnetic imaging and copy generation. The system disclosed in the figure shows apparatus for moving a magnetic tape 1 through supply, imaging, storage, development, transfer and take-up stations. Latent magnetic images are generated on a magnetic tape at imaging stations 2, utilizing techniques known in the magnetic imaging art. Copy sheets are stored in a copy sheet tray 4 and moved into transfer relationship with the magnetic tape at a pair of transfer stations 5, 6 by a copy sheet transport 7. Two storage dump containers 8, 9 allow continuous recording so that while a previous job is being developed and transferred, subsequent jobs can be imaged at the imaging station 2. The tape is subsequently wound on take-up roll 3.

MAGNETIC XEROGRAPHIC IMAGING SYSTEM (Cont'd)

The present disclosure relates to magnetic xerographic imaging and in particular, relates to a system architecture for providing simplex and/or duplex magnetic imaging and copy generation. The system disclosed in the figure shows apparatus for moving a magnetic tape 1 through supply, imaging, storage, development, transfer and take-up stations. Latent magnetic images are generated on a magnetic tape at imaging stations 2, utilizing techniques known in the magnetic imaging art. Copy sheets are stored in a copy sheet tray 4 and moved into transfer relationship with the magnetic tape at a pair of transfer stations 5, 6 by a copy sheet transport 7. Two storage dump containers 8, 9 allow continuous recording so that while a previous job is being developed and transferred, subsequent jobs can be imaged at the imaging station 2. The tape is subsequently wound on take-up roll 3.

The magnetic tape transport system includes a pivoted pair of transfer rollers 10, 11 which pivot between the solid line and phantom positions shown in the figure. Initially, the tape 1 carries precollated duplex and simplex latent images from a first storage container 8 past a first of the pivoted transfer rolls to a development station 12. The development station 12 includes a development roller 13 which is rotatably mounted for clockwise rotation to develop images which pass a first image developing zone 18. At the development stage a series of magnets, M1 - M4, are in the dotted line position to attract toner particles to the roller 13. After development of the latent images with a magnetic toner material, the images are moved along the transport path to a first transfer station 6 where magnetic toner images are transferred to a copy sheet moving in registration with the now developed images. The copy sheet moves away from this transfer station 6 to a simplex output tray 15 where it can be removed by the user or temporarily stored until a second duplex image can be transferred to it. On this first path of travel, the simplex images are fused by a tri-roll fuser apparatus 16. This process of image development and transfer continues until all simplex copies from a given job have been developed and transferred.

Once the simplex images have been fused, magnets M1 - M4 in the development apparatus are rotated to the solid line position and the two transfer rolls are pivoted so that now the second roller 10 is in transfer relationship to the copy sheet transport 7. The ma...
