I have been told ram disk acts like a hdd except that when the mach. is powered off you lose the stored data. Makes sence however I have been told many different reasons to use or not to use it.

Do any of you know for sure the full function of ram disk?

It allows the print job to be held in RAM until it is all printed. This is important for when "sort at printer" setting is on. If a finisher is used, it absolutely is required to staple jobs.

You'll find printing multiples from Adobe Acrobat Reader won't work at all without a RAM disk, only 1 copy will output. It also will reduce network traffic by only sending the print job once to the printer. If sorting is done by print queue, the job must be sent in full multiple times, also slowing total print time.

A hard disk will also do these functions, and RAM disk is turned off when a hdd is installed.

Thanks, Thats what I thought. What size as a percentage of memory or percentage of user available memory do you recomend?

you need to turn ram disk on when you do not have the hard drive for stapling multiple sets when you have a sorter. Go into FPRO values and turn this on and bump up the memory to around 70.

RAM disk size typically is at least 1/3 system RAM size. This can be decreased some if the system RAM is expanded a lot. On some printers I've set the RAM disk as large as 32MB because they had an error making 50+ sets of a multi-page print job. That was with 188MB system RAM installed.
