■ On-site checkout
The most common cause of a hardware problem is a faulty or loose connection. Before you replace a costly component, check
the connections between the printer and the imagePASS first, and then check the connections between each imagePASS
component.
For more information, see the following topics:
• "imagePASS connector panel and LED diagnostic codes" on page 14
• "Checking imagePASS internal connections" on page 17
For more information about servicing and troubleshooting problems with the printer, see the documentation that accompanies
the printer.
■ Symptoms and solutions
For various problems and possible actions, see the following table. To learn possible causes and solutions for a specific error
condition, find the symptom in the charts and perform the appropriate suggested actions in the order listed in the numbered steps.
Verify functionality after each numbered step. Proceed to the next numbered step only if the problem persists. For example, in
the steps:
1. Check and reseat the printer interface cable.
2. Replace the printer interface cable.
Perform step 1, and then verify functionality. If the problem is resolved, do not perform step 2.
