Analyzing the Print Test
Print Tests provide several uses in troubleshooting the printer problems.
• Isolating problems to either the print engine (printer engine card assembly) or to the RIP card
assembly and host software.
• Locating feed and media transport problems.
• Detecting print quality and image registration problems.
Using print test to locate a feed or media transport problem
Use Print Tests to locate a problem with media feed or with media transportation along the media path.
1. Enter Printer Diagnostics and generate a Print Test.
2. Follow the media along the media path until the problem occurs.
Using print test to analyze a print quality problem
Due to the method used to generate Print Tests, grid lines may display a noticeable amount of jitter or
unevenness. This is normal for Print Tests.
1. Print a sample image from the host computer.
2. Enter Printer Diagnostics and generate a Print Test.
3. If the print quality problem occurs when you print from the host computer but does not occur when you print
from Diagnostics, the problem may be in the RIP card assembly, in the print driver software, or in the
application software on the host computer.
4. If the print quality problem occurs on the Print Test, then the problem is caused by the print engine.
5. If the print quality problem is an image registration problem, go to “Setting Printer Registration” on
page 3-31.
