Test Prints
Table 1 describes the test patterns and the purpose for which they should be used to identify
image quality defects.
Test Print 1, 2
TP 1 and 2 provides a variety of different line styles in both process and cross-process direc-
tions. The pattern is used to check registration, dot size and image density.

IQS 1 Solid Area Density
Documents
TP 1 or TP 2 and the solid area density scales, 82E8230 (SIR 542.00) or 82P448 (SIR
494.00).
The Phaser 4600/4620/4622 is ISO11798 compliant with archival paper. Image density is no
less than 90% across core media list. Media must fix toner well enough to pass taping test.
Using a 500g weight, after rubbing the test pattern 5 times, calculate the ratio of pre- and post-
test data (density).
After taping test, the image density of black area of test pattern should be higher than 80% of
its original density in standard paper under N/N environmental condition.
Specification
Print the TP 1 or TP 2 test pattern. Compare the print with the solid area density scale. The den-
sity of the 1.0 areas on the print of the test pattern, must be as dark or darker than the 0.8 ref-
erence on the solid area density scale of the SIR Pattern.
Corrective Action
Go to the IQ1 Image Quality Entry RAP.
