• Typically, heavy weight papers exhibit increased variability of formation and surface
smoothness, which may result in degraded image quality.
• Preprinted “shells” from offset printers negatively impacts reliability and image quality
based on coverage and other factors.
• Manufacturers of coated stock do not recommend use of their media when the ambient
relative humidity exceeds 60%.
• All paper stretches to a certain extent during printing. The amount of stretch is
dependent on paper type and environmental conditions. Stretch is most noticeable on
coated stocks. This stretch can affect front-to-back image registration.
• Image registration, image quality, and machine reliability can be adversely affected when
custom-cut paper is inaccurately cut, is of poor quality, or loose paper fibers are present
on the cut edges.
• Image registration, image quality, jam frequency and machine reliability can be adversely
affected when punched or drilled paper is of poor quality and/or loose hole plugs are
present in the ream.
Image Size, Print Area and Registration
The maximum image area this family of EPS can create is 12 in. x 18.9 in. (305 mm x 480 mm).
The standard area that can be printed leaves a margin of 4.1 mm on all four edges of the paper
(for 11” x 17”, SRA3, 320 mm wide). The actual printing area may vary depending on the printer
(plotter) control language.
±0.76mm at 2σ (±1mm at 3σ) lead registration
±0.72mm at 2σ (±1mm at 3σ) side registration
Production Speeds
The rated speed for the Xerox 4112 EPS and Xerox 4127 EPS are 110 and 125 pages per
minute, respectively. These speeds are achievable in optimum conditions using Letter/A4 sized
media, long edge feed, and discounting startup delays like warm-up time and time to clear the
paper path. Use of finishing features, multiple paper trays and other factors affect the productivity
of all printing devices to some degree.
The output speed of a print job is affected by:
• Use of finishers and finishing features (e.g., stapling, hole punch, folding, and Booklet Maker
will slow down print speed)
• Job length
• Using the Bypass Tray or High Capacity Feeder
• Single-sided versus two-sided job
• The time it takes to RIP a job based on the type of PDL
• Other factors outside the control of the product
Print Speed
Print per Minute (PPM) of the print engine using a common configuration is defined as below.
Timing of throughput is measured with one original by the time taken after the trail edge of the 1st
sheet is fed until the trail edge of the 11th sheet is output to the top tray. Throughput is measured
using the system trays (1,2,3,4) and the High Capacity Feeder (HCF) Option (6,7) with output to
the top tray.
