I'm now out of the biz, retired, but the Sales Information Guides available on-line have a matrix in the back that shows compatibility of accessories. Also that are detailed specs on each accessory) so that you can make sure the customers needs can be met with your offering. As I recall there are significant limitations with the various booklet makers. Also remember that booklet makers fold 11x17 (12x18's) and there are click charges to consider. Also the cover inserter can be utilized to insert add'l 11x17's (12x18's) allowing end-users to add color even inside a document. Study up well on these devices and their flexibilities. Good Selling.
