Note:

The 7893 will flash sequences of changing colors that match the Scan Advisor (5-LED 

light bar) color sequences used on other PXA scanners like the 7884. Except that the 7893 

must flash the colors in sequence instead of displaying them all at once. 

Service Diagnostics 

Scan Doctor includes service diagnostics for the trained service technician. These go beyond 

the wellness checks and are accessed through the use of special programming tags. Refer to 

Appendix C for more information on the Scanner Service Diagnostics Tests. 

Soft Power Down/Power Up 

The 7893 can sense periods of scanner inactivity. The scanner's soft power down feature 

extends the life of the 7893 by disabling major portions of the unit, which includes the laser 

diode, spinner motor, and associated electronics. The length of the inactive period prior to the 

soft power down is user-selected and programmed remotely or through tags. 

Scanner power up occurs when the 7893 motion detector detects movement. This detector is 

located inside the scan window. The 7893 can also be powered up when the checker signs on 

the host terminal. This capability assumes appropriate host terminal software.
