Manual document feeding

In its normal “on-line” mode of operation the 2750 automatically processes documents passed from the printer. The 2750 also allows off-line operation, accepting hand-fed documents for folding. Because the width measuring system in the bridge is inactive when the folder is off-line, hand folding has limitations which do not apply to on-line operation:

•

•

Bookfolding is not possible.

The final fold in the on-line process delivers two equal-width panels. In the manual mode the last panel is simply the surplus resulting from accordion folding, ranging in width from 3½” (90mm) to the selected accordion panel width.

•All documents are treated as “SEL” (Short Edge Leading), and should be entered that way: for example, a 22” x 34” print should be hand-fed with the 22” edge leading. There is nothing to stop you feeding it long edge first, but this gives unpredictable results and should be avoided.

•Neatness of the folded packet depends on the operator. If the document is skewed as it enters the infeed slot, the skew will multiply with each accordion fold to give an undesirable fan effect. This means that care must be taken, particularly with documents over 50” (1.25m), to square up the leading edge of the document.

Handfeed Mode is invoked by pressing the HANDFEED Button on the Operator Control panel sending a signal to the host controller that the folder is off-line and unavailable for processing a job. The user will not be allowed to enter Handfeed Mode while the folder is processing a job or if the folder has received a sheet coming command from the host signaling the start of a new job. Attempts to invoke Handfeed Mode under these circumstances will result in an audible beep.

If the folder is not connected to a host controller be sure the printer is inactive and the last print has exited the folder before invoking Handfeed Mode. When the Handfeed Mode is active, the bridge diverter will disengage, creating a barrier to incoming prints. Prints exiting the printer will fall to the floor below the bridge. Be sure to deselect hand feeding when the handfeed operation is completed.

Once the folder has entered Handfeed Mode, the display will show the available fold programs with an asterisk indicating the active program. Note that the button-to-program assignments may vary from those available on-line. This is a key operator or technician setup.

If an attempt is made to handfeed and the HANDFEED push-button is not depressed, a warning beep will sound.
