Page 77: Image Quality Defect Definitions
Image Quality Defect Definitions The System Controller Test Print (Figure 1) is used to evaluate each of the print quality param- eters. Each area of the test pattern is used for a print quality parameter. The areas and the print quality parameters are listed in Image Quality Checkout. Table 1 Image Quality Defect Definitions Defect Definitions Go To:...
Page 78: Image Quality Checkout
Image Quality Checkout The System Controller Test Print is used to evaluate and ensure that the printed image meets the printer specifications. Use new paper, whenever possible, to check the image quality of prints. Make five (5) prints of the System Controller Test Print (Figure 1).
Page 79: Solid Area Density
Solid Area Density Background Procedure Procedure Ensure the printer is set for 600 dpi. Compare the solid areas on the System Controller Test Compare the Test Prints with the Visual Scale (82P284). The worst background area on any Patterns with the Output Reference document (82P520) (Figure 1).
Page 80: Deletions (Line, Band, Spots)
Deletions (Line, Band, Spots) Fusing Procedure Procedure Inspect Test Prints for the presence of deletions (missing image). There should be no deletions NOTE: The operating environment of the printer is from 41 F (5 Celsius) at 15% relative with a diameter larger than 0.5 mm visible on test prints (Figure 1).
Page 81: Resolution

Page 264: Gp 3.1 Print Process Overview
GP 3.1 Print Process Overview Print Process Overview (Figure 1) (Figure 2) There are seven steps in the N2125 print process. This seven step cycle is repeated for each sheet of paper that is sent through the printer. The seven steps in the print process are: Charge A bias charge roll places a uniform negative electric charge on the drum surface.
Page 265 The Magnetic Roll maintains an electrical potential relative to the charged surface of the drum. Negative charged areas of the drum have a lower electrical potential, or higher rel- ative negative value, than the Magnetic Roll. Discharged areas of the drum have a higher electrical potential, or lower relative negative value, than the Magnetic Roll.
Page 266 Figure 6 Side View Block Diagram of the Discharge Process Fusing (Figure 7) The paper moves to the Fuser Assembly where it passes between the Heat Roll and the Pressure Roll. The Heat Roll melts the toner image and bonds it permanently to the paper.
Page 267: Gp 3.2 The Paper Path
GP 3.2 The Paper Path There are three paths that a sheet of paper can follow during a feed cycle (Figure 1). One path is taken if paper is fed from the Paper Tray. Another path is taken if paper is fed from the Multi- ple-Bypass Feeder (MBF).
