Setting the Media Sensitivity Number
The media sensitivity number (MSN) is important, because you use it to
optimize print quality and print speed. The three-digit MSN specifies the
amount of heat required by the printhead to image a label. The amount of
heat that each roll of media or ribbon requires is unique due to different
chemistries and manufacturing processes.
Intermec has developed heating schedules (the amount of heat required to
image a label) to produce the highest possible print quality for Intermec
media and ribbon combinations on Intermec printers. Look for the three-
digit MSN on
• the side of the media roll. Use the last three digits (140 in the example)
of the 15 digit number stamped on the roll for the MSN.
• a small label attached to the roll of media.
• a small label attached to the plastic bag of your ribbon roll.

MSN:
This illustration shows you where to find the MSN. Note that some ribbon rolls
have the MSN printed inside of the core.
Use this three-digit number to optimize print quality and print speed on
the printer. You can achieve the best print quality on the 4420 or 4440
printer by using only Intermec ribbon and media products. This table lists
