Threading a duplex system

This section describes how to thread a duplex system to achieve the following configurations:

Threading a duplex system in a straight-line (inline) configuration

Do this procedure to thread a duplex system set up in a straight-line (or inline) configuration. For InfoPrint 4100 Models HS2, HS3, HD3/4, and HD5/6, you must thread both the Tall Buffer/Flipper and the Air Bearing Buffer/Flipper to achieve a straight-line configuration. For InfoPrint 4100 Models MS1 and MD1/2, you must thread the Tall Buffer/Flipper.

Use the following illustration when threading forms for a straight-line configuration for InfoPrint 4100 Models HS2, HS3, HD3/4, and HD5/6.

Use the following illustration when threading forms for a straight-line configuration for InfoPrint 4100 Models MS1 and MD1/2.

Procedure:

  1. Thread the forms through the Tall Buffer/Flipper using the following illustration as a guide. Use the numbered arrows as guides starting from Printer 1 at the middle of the figure (1) to Printer 2 at the bottom of the figure (5). The result is that the forms are buffered between Printer 1 and Printer 2.
    Note:
    The guide collars on the roller bars, denoted by letters (A) through (C), were adjusted properly when the system was initially installed. Making adjustments is probably not necessary, even if you are threading a form through the system with a different width than you previously threaded.
  2. If the Air Bearing Buffer Flipper is installed, thread the forms using the following illustration as a guide. Use the numbered arrows as guides starting from Printer 1 at the middle of the figure (1) to Printer 2 at the bottom of the figure (5). Make sure to thread the forms under the brush and over the air bearing turnbar at (1). The result is that the forms are inverted 180° between Printer 1 and Printer 2.

Threading a duplex system in a left-angle configuration

Do this procedure to thread a duplex system set up in left-angle configuration. You must thread the Tall Buffer/Flipper to achieve a left-angle configuration.

Use the following illustration when threading forms for a left-angle configuration.

Procedure:

Thread the forms through the tall Buffer/Flipper using the following illustration as a guide. Use the numbered arrows as guides starting from Printer 1 at the middle of the figure (1) to Printer 2 at the bottom of the figure (5). The result is that the forms are inverted 180° between Printer 1 and Printer 2 and also make a 90° turn.

Note:

Threading a duplex system in an H configuration

Do this procedure to thread a duplex system set up in an H configuration, which is used for printers configured so that the fronts of both printers face in the same direction. You must thread the Tall Buffer/Flipper Unit and a turnbar to achieve an H configuration.

Use the following illustration when threading forms for an H configuration.

Procedure:

  1. Thread the forms through the Tall Buffer/Flipper using the following illustration as a guide. As the form enters the flipper, its rear edge should run close to the collar. Use the numbered arrows as guides starting from Printer 1 at the middle of the figure (1) to Printer 2 at the bottom of the figure (6). As the form leaves the 45° bar, the edge should line up with the tractors of Printer 2. The result is that the forms are inverted 180° between Printer 1 and Printer 2 and also make a 90° turn.
  2. Thread the forms through a turnbar. The result is that the forms are inverted 180° again and make another 90° turn.
