10.0 Troubleshooting Guide  

This is a simplified troubleshooting guide listing some of the typical problems.  It is not intended to provide 
technical details or repair methods, but can serve as a guide to fault isolation in the field.  

As a safety 

precaution, all service to the printer should be done by 

qualified persons

 with power off and 

the AC cord unplugged from the printer

.  

Following any procedure requiring the removal of 

covers and/or doors, please verify that they have been properly attached and fastened prior to 
operating the printer.  

If you need additional help, please contact BOCA at
