unstable, it may cause the paper to expand or shrink, resulting in curled paper�
• For the appropriate temperature and humidity, see the Installation and Operating Environment Guidelines or the
Specialty Media Handling Guide�

and humidity�
• Unwrap the paper immediately before you load it into the machine�
