Xerox 5252 manual Store Paper

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 air-tight moisture proof container.
	• 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 state-of-the-art rotary slitters on high
	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 in-house maintenance program,
	including knife sharpness maintenance and dust removal with a
	vacuum or air system, are key to achieving good results.
