A customer has sent us a pdf for us to print out on our 700i as they are having print issues with their machine and we want to test the job here. However, when I upload the file into command workstation and go to print it the job throws up an error saying 'The required finisher (HCS Stacker) is not installed' and won't print the job. The machine has an OCT and this is selected when I go into job properties so I'm a little confused why it won't print the job.

Any help with this would be greatly appreciated, I apologise if some of this is not clear as I am a bit of a novice with this software.

thanks in advance
