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.
