Service and error messages

Service errors prevent further printer operation until some action is taken. When there is a service error, all of the lights will turn on in a steady state. Press and hold the Control Panel Button to see a pattern in the lights. (The error will only be displayed as long as this button is pressed.) Use Table 7-4, “Service and Error Messages,” to identify what type of service error has occurred.

3. Remove the connector from J102

 

 

 

 

of the DC Controller (See Figure 6-

between pins one and two of the

 

 

 

 

cable. (This procedure will measure

 

 

 

 

the continuity of the ceramic heating

 

 

 

 

element.) Normal resistance is 30

 

 

 

 

ohms +/- 10 ohms. If no resistance is

 

 

 

 

measured, replace the heating

 

 

 

 

element.

correct, yet the error persists,
