Hard Disks
Use the Administration/Disk Operations menu to format the internal
hard disk or connected hard disks.
See the Options manual for more information on installing external
hard disks.
▲ Caution: If you connect to this printer an external hard disk you
previously used with an earlier QMS Crown printer (QMS 1660E,
QMS 1725E, QMS 2025, or QMS 3225 ), this QMS 4060 Print
System software release will automatically reorganize the files on the
hard disk when the printer is turned back on again. (The printer
release number is listed on both the start-up and the status page.)
Once this reorganization is done, the files on the hard disk can no
longer be accessed if the hard disk is reattached to an earlier QMS
Crown printer.
This reorganization process takes time. If, when you first turn the
printer on after attaching a previously used hard disk, it does not
come on line immediately, be patient. Interrupting the reorganization
process could cause all files on the hard disk to be lost.
