●Pages must be all color, or all grayscale: not some in color and some in grayscale.
●All pages must be in one or other of the following two groups (the two groups cannot be mixed in the same nest):
●
●PostScript, PDF, TIFF, JPEG

How long does the printer wait for another file?
So that the printer can make the best nest possible, it waits after a file has been received to check whether a subsequent page will nest with it or with pages already in the queue. This waiting period is the nest wait time; the factory default nest wait time is two minutes. This means that the printer waits for up to two minutes after the last file is received before printing the final nest. You can change this
waiting time from the printer's front panel: select the 
icon, then Job management options > Nest options > Select wait time. The available range is 1 to 99 minutes.
While the printer is waiting for nesting to time out, it displays the remaining time on the front panel. You can print the nest (cancel the nest wait) by pressing the Cancel key.
