macOS Sierra with a C75 Press Fiery: Inserting a pre-printed cover in a booklet

[KingdomEMC]

I already have Command Workstation installed.  I use it quite often.   I've tried adding the cover in the bypass of the C75 and indicating as such in the Command Workstation, but it's still giving me fits.   The gal who has the actual work document is not here the rest of today.  Tomorrow morning when she gets here, I can get the actual file from her.  I've been working with a "sample" doc to try and figure it out before she's ready.  

On another hand, I've spoken with the sales office that we got it from, and the gal there is having me call her in the morning so she can talk us through it, or she will come over and help us set it up.

Joe, thank you, for your willingness to help.  Hopefully, I won't have to bother you anymore. 

Blessings,

Tammy

Just install Command Workstation and set the cover option in there instead of in Acrobat or the driver on the Mac.

If it fails there, archive the job in Command Workstation, zip the archive and post it so I can retrieve it and test in the lab on out C75 with Fiery.

I work for a large church and we have a Xerox C75 Press with Fiery.  I use an iMac and the operating system is the macOS Sierra.

Quarterly, I print an 8-1/2 x 11 magazine on 11x17 paper with no problems whatsoever.  

HOWEVER....our office needs to print a 5-1/2" x 8-1/2" booklet, but wants to insert an already pre-printed cover on the outside of it, prior to folding/center stapling.  I've tried using the very same settings as I usually do on the Fiery for the larger magazine, only changing the paper sizes, etc.  I'm saving each page, in order as PDFs, using the fiery, etc. like I always do.   I've tried adding the cover in the bypass and indicating as such in the Command Workstation, but I'm having terrible trouble. The bypass simply will NOT spit out the cover to include it.  And on top of it, NOTHING will print when I try this.  Other projects, papers,  sheets, etc. print just fine, but this print job is giving me real headaches.  These need printed tomorrow or Monday, so I'm trying to get this figured out so when she comes in tomorrow, we have no snags when she's absolutely ready to print them.

Thank so much, in advance for any help you can give me.
