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 Front 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.

ROM/RAM Error. An error was found with

 

1. Power-cycle the printer by unplugging the printer

 

 

 

the ROM or RAM. The printer believes that

 

and plugging it back in. If this doesn’t clear the error:

 

 

 

 

 

 

 

the ROM is corrupted or an error has been

 

 

 

 

 

found in the RAM.

 

2. Unplug the printer, remove any optional memory,

 

 

 

 

 

 

 

 

 

 

 

 

 

 

then power the printer back on. If the message

 

 

 

 

 

 

 

 

 

 

 

 

clears, replace the memory card.

Controller (See Figure 6-14). Measure the resistance

 

 

 

 

 

 

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.

 

 

 

 

 

 

4. Remove the thermistor (temperature feedback)

 

 

 

 

 

 

connector (See Figure 7-3). Measure the resistance

 

 

 

 

 

 

between pins one and two. Normal resistance is

 

 

 

 

 

 

440K ohms +/- 30K at 20 degrees C. If the resistance

 

 

 

 

 

 

is not measured replace the heating element.

 

 

 

 

 

 

5. If the resistance readings are correct, yet the error

 

 

 

 

 

 

persists, replace the DC Controller.
