ers to the printer.
26. Close the top cover.
27. Turn the power on. Print a test page -
selected from the service mode MENU
of the operation panel.
28. Check that there is no fault in a print out.
Note: After the LED print head has been replaced, the printer requires approximately 30 seconds until it
gets ready. This is required because the printer needs to download the data stored in the EEPROM
mounted on the LED print head for optimizing the LED print head performance.
Caution: If there is a fault with the test page or a fault is displayed on the self-diagnostic display, check
the following:
If the test print image is partly missing or a fault is displayed:
The FFC connection to the LED print head (Step 12).
The FFC connection to the printer (Step 23).
The positioning of the blue and white FFCs - ensure they are in the correct order (Step 23).
Damage of FFC.
If test print is blurred or out of focus:
The state of press spring (Step 20).
