Standard Procedures
There are several symptoms which may be observed when the printer malfunctions :
§ No power.
§ The printer can be powered but there is no LED/LCD activity.
§ An error message (Recoverable or Unrecoverable) is displayed.
§ No error message is displayed but a problem exists: paper is not picked or is
picked up multiply, problems in print quality, broken or loose parts.
Do the following checks and preparations before going into further troubleshooting.
1. Check that the ink cartridges, the printheads and power cord are properly installed.
2. Check that the top cover and the rear door are properly closed.
3. Switch off the printer. Disconnect the printer cable and remove the MIO card (if
available). Then switch on the printer again.
4. If the printer LCD panel displays a error message, refer to Error Codes (Chapter 2)
for the interpretation of the error message.
