Selecting stock Xerox Nuvera
1-12 Paper Guide
Cut quality
The accuracy of the sheet cutting process affects paper handling and image quality.
When paper is cut with a dull blade, edges stick together to form “edge welds,” which cause
paper jams and excess paper dust in the printer. Paper dust is also created when folio sheets are
cut from the roll. A good paper mill takes steps to remove dust from paper before wrapping it.
Loose fibers on the edges of cut sheets can lead to printer contamination and visible fibers
within printed images.
If the cut is not exactly square, skewing, jams, and stacking problems can occur. Image quality
defects also occur due to misregistration in the paper path.
Slight variations in sheet cut size can also cause sheet to sheet registration problems in bindery
operations.
In-house trimming and paper cutting
Xerox recommends the use of pre-cut paper in the Xerox Nuvera.
Note
If you must cut sheets before printing, an in-house maintenance program that ensures
knives are kept sharp and dust is removed with a vacuum or air system will be key in
achieving good results. Failure to do so could result in excessive downtime and service calls.
If a custom cut is required, it is recommended that you use a rotary slitter.
Xerox recommends trimming sheets after printing has been finalized to prevent the generation
of paper dust and printer contamination issues.
Surface strength
Fibers, additives, and coatings can rub off of sheets as they are pulled through drive rollers.
Papers with good surface strength shed fewer fibers and particles, which helps prevent the Xerox
Nuvera System from becoming contaminated over time. System contamination causes
jamming throughout the system, image quality problems, and fuser wraps (fuser agent
becomes contaminated).
Electrical properties and paper handling
Paper naturally resists electrical current, which can lead to static build-up between sheets. Static
can cause multifeeds, jams, and stacking problems.
To obtain proper resistivity, paper manufacturers add salt and other materials during the paper
manufacturing process. They also pack paper in moisture-proof packaging to maintain
resistivity.
For best performance, choose paper with low resistivity, and observe the storage guidelines in
Chapter 2, Managing your paper supply.
