1. To perform the Troubleshooting procedure press the or key until the front panel displays the Ink Menu and then press Enter.

2. Press the or key until the front panel highlights Troubleshooting and then press the Enter key.

3. The Printer first checks to see whether the Printheads have been aligned recently. Misalignment of the Printheads is a common cause of Print Quality problems, so if the Printheads haven't been aligned recently, you are prompted to accept the alignment now.

NOTE: The Printhead Alignment requires a few centimeters of Paper loaded and takes several minutes to perform.

4. If the Printheads do not seem to require alignment, the Printer prints the Diagnostic Print A, which contains several blocks of color and a block of thin black broken lines.

5. Examine the broken lines carefully and when prompted by the front panel, indicate whether there are problems with them. The sorts of problems to look for are:

Jaggedness or serrations in the thin lines, like this:
The lines should be straight, though not necessarily perfectly aligned. The irregularities that are significant extend along the whole of the length of the lines. Shorter irregularities, arranged in columns, can be ignored at this stage.

6. If you indicate that there is a problem with the dashed lines, you are prompted to perform the Advance Calibration procedure.

7. If you indicate that the broken lines in Diagnostic Print A are OK, then examine the blocks of color carefully and when prompted by the front panel, indicate whether there are problems with them. The sorts of problems to look for are:

White streaks or bands in the solid blocks.

8. If you indicate that there are problems in the blocks of color, the Printer will try and clean the Printheads that have the problem. A Printhead can be cleaned up to 3 times in this way after which it will need to be replaced (you will be informed via the front panel).

9. After cleaning the Printheads, the Printer reprints the Diagnostic Print A, and you need to repeat the previous steps.

10. If you indicate that the blocks of color in Diagnostic Print A are OK, the Printer will print Diagnostic Print B.

11. For each color in the pattern in Diagnostic Print B, you are asked about the quality - look especially for missing lines. If you indicate that a color is defective, the Printer tries to clean that printhead.

12. After cleaning the Printheads, the Printer reprints the Diagnostic Print B, and you need to repeat the previous steps.

13. If none of the patterns or blocks in the 2 Diagnostic Prints show any problems, it could be that the Print Quality problem is caused by a wrong setting in the software, or maybe the print job should have been printed with Print Quality set to Best instead of Normal or Draft.
