The Calibration Link function is accomplished by performing color 
calibration  utilizing an imagePROGRAF iPF6400S  printer in the linked 
chain.  
The printer prints a page of calibration targets that are measured with the 
Spectrophotometer Unit SU-21 mounted on the imagePROGRAF 
iPF6400S printer. The Calibration data is stored and sent to other printers 
in the Calibration Link.

C.  Multisensor 
The Multisensor is capable of sensing and calibrating third-party 
imagePROGRAF  print  media.  The specialized lens with its small focal 
diameter improves image detection, and image variation tolerance. 
Separate edge detection, gap detection, and density detection functions 
also work to optimize custom media support. The sensor’s design offers 
increased tolerance to external light thereby  allowing some of its 
operations to be visible from the transparent observation windows on the 
printers cover.
