the problem is with the scanner

the problem is the diagnostics light is flashing

An error is detected by the built-in diagnostic.

1.The scanning area needs cleaning. For cleaning instructions see maintenance procedures on page 24.

2.If the Diagnostic light continues to flash after maintenance, then there may be camera position errors. See tell me about hp customer care on page 90.

the problem is the wait light is flashing

When the Wait light is flashing (and the Diagnostics light is off) readjusting is needed, but not possible.

1.Remove any original in the scanner.

2.Return the Original Pressure Platen to the normal position (also in this situation a scan may be issued, but the quality will be compromised).

When adjusting is again possible, the Wait light stops flashing, but continues to be on until the self-adjust is complete.
