Creating Thumbnails (MFP models only)
• The MFP creates thumbnail images in JPEG format for the first page of the image files stored in the
HDD. The thumbnails themselves are also stored in the HDD as well. The specific operations
performed by the MFP to create the thumbnails depend on whether or not the File Format
Converter is installed.
• When the File Format Converter is not installed:
 When the image data is saved to the HDD, the MCS uses its modules to create a thumbnail of the
first page of the image data.
 When the File Format Converted is installed:
When the image data is saved to the HDD, the IMH uses its modules to create a thumbnail of the
first page of the image data. The first page is read into memory, after which the File Format
Converter compresses it and converts it into image data. The MFP software then creates the
thumbnail from this data. If a request is received for thumbnails for page 2 or onward, Netfile
sends the request to the IMH via the MCS. The IMH then generates the thumbnail for the
requested page(s) in the same way as described above for page 1.
Viewing Thumbnails (MFP models only)
• Netfile loads the requested thumbnail data directly from its storage location on the HDD, and then
sends it to the PC via the NCS.
Deleting Thumbnails (MFP models only)
• When the number of thumbnails for pages 2 and onward created at the request of Desk Top Editor
for Production reaches a certain limit, Netfile will choose the oldest thumbnail and send a request to
the MCS to delete it. The MCS then deletes the specified thumbnail from HDD memory. Also, the
MCS deletes all thumbnails for pages 2 and onward from HDD memory whenever the main power
is turned on or a system reset is performed.
