NOTES:
 
• 
To optimize your printer’s performance, always use clean, 
unused media. 
• 
Be careful not to leave fingerprints on the media, which can result 
in a smudged print. 
• 
Reusing media that has been fed through the printer once (for 
example, after jams) can reduce the life of the consumables and 
paper path components.

The recommended transparency is 3M CG3700. 
 If the print 
quality is poor, try printing on the other side.
