Preprinted papers such as letterhead must be able to withstand temperatures up to 190°C (374°F) without melting or
releasing hazardous emissions.
Storing paper
Use these paper storage guidelines to help avoid jams and uneven print quality:
• For best results, store paper where the temperature is 21°C (70°F) and the relative humidity is 40%. Most label
manufacturers recommend printing in a temperature range of 18 to 24°C (65 to 75°F) with relative humidity between
40 and 60%.
• Store paper in cartons when possible, on a pallet or shelf, rather than on the floor.
• Store individual packages on a flat surface.
• Do not store anything on top of individual paper packages.
