A digital copying and printing system associated with a computer network for prioritizing and executing copy and print jobs. Two central processing units share the prioritizing and interpreting of copy and print jobs, so that the copy and print jobs are performed in a highly efficient manner.

Architecture for a digital copier and printer for handling print jobs

This invention is directed to new electrophotographic, and magnetic toners, which are useful for example in high speed fusing systems, these toners being comprised of a polyamide resin, a pigment or colorant, which pigment or colorant may be magnetic and as an optional ingredient, a carrier material. The polyamide resin is of the formula ##STR1## wherein R, R.sub.1, R.sub.2, and R.sub.3 are radicals independently selected from aliphatic, substituted aliphatic, aromatic, substituted aromatic, cycloaliphatic, and heterocyclic, x is a number of from 1 to about 100, and y is a number of from 1 to about 100. In one preferred embodiment the toner composition is comprised of the polyamide resin and a high loading, 50-75 percent of a magnetic material, allowing for high speed fusing in magnetic imaging systems.

A storage buffer for a moving web comprises a collection bin having an opening through which the web can be randomly dumped under the influence of gravity; means for floating randomly dumped web within the collection bin upon a cushion of gas without mechanical support of said web; a web exit within a wall of said collection bin; and means for guiding pressurized gas over web passing through the web exit.

Random-dump storage buffer for moving web

A storage buffer for a moving web comprises a collection bin having a bottom triangular cavity, a top opening through which the web can be randomly dumped under the influence of gravity and a bottom opening through which the web is withdrawn from the collection bin on a first-in, first-out basis. The sloping bottom walls of the collection bin are provided with ridges to assure the maintenance of a gas bearing beneath the bottom-most layer of exiting web. Nozzles for directing pressurized gas into the collection bin are located on both sides of the web at the collection bin exit.

An electronically controlled magnetic recorder for rapidly optically scanning an original document and for producing a latent magnetic image thereof. The recorder comprises directly coupled helical optical scanning and helical magnetic writing.

Synchronous helical scan-helical record magnetic imaging

An improved magnetic interpositive imaging method is provided by creating an electrostatic latent image in a photoconductive member comprising photoconductive material dispersed in a binder; developing by touchdown development said electrostatic latent image with toner comprising from about 10% to about 60% by volume hard magnetic material; fixing said toner to said photoconductive binder; magnetizing said fixed toner; and, transferring the magnetic signal from said magnetized, fixed toner by thermoremanent transfer of magnetization to a magnetizable recording medium.
