Paper and Paper Trays
| For reliable digital press operation and good print quality, Xerox |
| recommends the following: |
Store Paper: | • On a flat surface. Do not store paper directly on the floor, since |
| that increases the possibility of moisture absorption. Paper |
| should be stored on pallets, or shelves or in cabinets in an |
| area protected from extremes of temperature and humidity. |
| • In a low dust area. |
| • In a low humidity area. Humidity is one of the most important |
| steps to promote proper paper characteristics. Optimum paper |
| storage conditions include a relative humidity of 35% to 55%. |
| An increase in humidity can cause paper to develop wavy |
| edges. This occurs because the edges absorb moisture while |
| the rest of the ream remains unaffected. Wavy edges can |
| cause jams and misfeeds. |
| • In an |
| • In controlled temperature. The temperature in the room where |
| paper is stored can have a significant effect on how that paper |
| performs in the machine. Optimum paper storage temperature |
| is 68o to 76o F (20o to 24.4o C). |
| For additional paper handling information, refer to the Color |
| Materials Usage Guide. |
Cutting and Trimming | Proper cutting of the paper is important. Mills offering paper in cut |
Paper | sizes cut their papers using |
| performance systems. Slitting and edge trimming by circular |
| knives with dust removal at every cutting point prevents |
| contamination of the paper. |
| Trimming papers from parent sheets to get the desired output size |
| may generate dust if dull knives are used. The recommendation is |
| to delay trimming until printing has been finalized to prevent paper |
| dust generation and contamination. |
| If preprinting is imperative, an |
| including knife sharpness maintenance and dust removal with a |
| vacuum or air system, are key to achieving good results. |
