Print Quality Diagnostic Tips

General Terminology

Before diagnosing print quality problems, take a moment to understand the concepts below. This will
prevent confusion when diagnosing or escalating a problem.
1. Know your paper orientation when diagnosing a print quality issue.
References to direction such as horizontal and vertical must be made holding the paper in
-
portrait orientation (long edges to the left and right) with the printed side facing you. Don't
hold the paper in landscape orientation. See below.
2. Know the direction of the print when diagnosing a print quality issue.
3. References to the "Process" or the "Scan" direction mean the following (see picture below):
Scan or Scanning is the direction in
which the LED or laser writes to the
photoconductor and is across the
paper path.
Note: This printer uses one Laser Printhead which fires four scanning beams across the length of the
photoconductors. LED Printheads, on the other hand, fire a simultaneous beam across the
photoconductor.
For Training Purposes Only
Process is the paper's direction
through the printer that corresponds to
the rotation of the photoconductors.
