IBM 3000 manual Duplex Printing Applications

This power-driven roller assembly is on the ¯oor in the forms input area of the second printer of the system; the continuous forms are threaded through it. It assists in feeding forms from the Buffer/Flipper Unit under the printer into the tractor feed area of the printer.

Duplex Printing Applications

The following con®gurations support Duplex (double-sided) printing.

Duplex printing is achieved by arranging both a Model ED1 and a Model ED2 in series, separated by a Buffer/Flipper Unit. The ®rst printer in the paper path prints one side of a form. The forms then exit the printer through a Buffer/Flipper Unit, which inverts them before threading them through the second printer. The second printer in the paper path prints the other side of the form.

This publication calls the ®rst printer Printer 1 and the second printer Printer 2. Allowable printer system con®gurations are inline (see ªInline Con®guration for Duplexº on page 6), or a left 90° angle (see ªLeft Angle Con®guration for Duplexº on page 7). Only a Buffer/Flipper Unit may be between Printer 1 and Printer 2, but no preprocessing or postprocessing devices.

The forms path can be:

vFrom the forms input area of Printer 1 through to the output stacker of Printer 2

vFrom the forms input area to a postprocessing device at the output of Printer 2

vFrom a preprocessing device ahead of Printer 1 through to a postprocessing device at the output of Printer 2.

Both printers in the con®guration attach to a host system through the AFCCU. The AFCCU controls both printers simultaneously and is physically attached to Printer 2 in the con®guration.
