Chapter 3: Service Level Troubleshooting
Diagnostics Overview
The NCR 7169 Multifunction Printer performs four types of diagnostic tests to help
troubleshoot problems and to change the printer configuration. Each of these is
described in detail in the sections that follow.
• Level 0 Diagnostics (Startup)—the printer performs these tests during the startup
cycle. For more information, refer to Level 0 Diagnostics (Startup) on the next page.
• Level 1 Diagnostics (Printer Configuration)—allows configuration of the printer
using a Configuration Menu that is printed on a receipt. For more information, refer
to Level 1 Diagnostics (Printer Configuration) on page78.
• Level 2 Diagnostics (Runtime)—the printer checks the status during normal
operation. For more information, refer to Level 2 Diagnostics (Runtime) on page105.
• Level 3 Diagnostics (Remote)—the printer keeps track of counters during normal
operation.
• Vendor Adjustment—the printer performs this task in off–line mode. This allows
changing the mechanical settings and performing printer test. Modifications of these
settings should be done by service personnel only.
