The interleave process during duplexing is slightly different, depending on the size of the paper as described below.

Paper Length (mm)

Interleaved Sheets

Longer than 139.7 (HLT LEF), shorter than 216 (LT LEF)

5

Longer than 216 (LT LEF), shorter than 297 (A4 SEF)

4

Longer than 297 (A4 SEF), shorter than 364 (B4 SEF)

3

Longer than 364 (B4 SEF), shorter than 432 (DLT SEF)

 

Longer than 432 (DLT SEF), shorter than 457.2 (12"x18")

 

Longer than 457.2 (12×18in), shorter than 487.7 (13"x19.2")

 

Five Interleave Sheet Flow

In this example, the flow follows this sequence: 1st front side > 2nd front side > 3rd front side > 4th front side > 5th front side > 6th back side > 2nd back side > 7th front side > 3rd back side > 8th front side > 4th back side > 9th front side, and so on. Refer to the illustration below.
