3.
Remove and re-insert all the printheads, see
Remove a printhead on page 63 and Insert a
printhead on page 66. This starts the printhead alignment procedure.
4.
Ensure the window is closed, as a strong light source near the printer during printhead
realignment can affect alignment.
5.
The process takes about six minutes. Wait until the front-panel display shows the process complete
before using the printer.
NOTE: The printer prints a calibration image. Do not worry about the image. The front-panel
display shows any errors in the process.
Image Quality Maintenance menu procedure
1.
Load the paper you wish to use, see
Handle the paper on page 29. You can use a roll or cut
sheet, which must be A3 landscape or larger: 420 × 297 mm (16.54 × 11.69 in).
CAUTION: Do not use transparent or semi-transparent paper to align the printheads.
2.
From the front panel, select the Image Quality Maintenance menu icon
, then Align
printheads. The printer checks to see if it has enough paper to run the realignment.
3.
If the loaded paper is satisfactory, the printer runs the realignment and prints a realignment
pattern. Ensure the window is closed, as a strong light source near the printer during printhead
realignment can affect alignment.
4.
The process takes about five minutes. Wait until the front-panel display shows the process
complete before using the printer.
Scanning errors during alignment
If the alignment process fails, a Scanning problems message appears on the front panel. This means
that the alignment has not completed successfully. Therefore the printer is not aligned and the alignment
should be repeated before printing with good image quality. The problem may be due to:
●
The paper used was not valid, repeat the alignment with valid paper
●
Printhead health problems, clean printheads, see
Clean the printheads on page 165
●
The alignment was done with the window open, repeat the alignment with the window closed
If the problem persists after using valid paper, cleaning the printheads and keeping the window closed,
there may be a failure in the scanning system needing reparation or the printheads, although clean,
may not work and need to be replaced.
The Image Diagnostics Print
The Image Diagnostics Print consists of patterns designed to highlight printhead reliability problems. It
helps you to check the performance of the printheads that are currently installed in your printer, and
whether any printhead suffers from clogging or other problems.
