Align the printheads
Precise alignment between printheads is essential for accurate colors, smooth color transitions and
sharp edges in graphical elements. Your printer has an automatic printhead alignment process which
runs whenever a printhead has been accessed or replaced.
In cases where the paper has jammed, you have used a custom paper, or are experiencing problems
with color accuracy, see
Color management on page 59; you may need to align the printheads.
NOTE: If the paper has jammed, it is recommended that you reinsert the printheads and initiate the
realignment procedure with the Image Quality Maintenance menu
.
TIP: Photo paper is recommended for the best quality; plain, bond and thin coated papers provide
acceptable but marginal results.
Do not use transparent or semi-transparent paper to align the printheads.
Reinsert printheads procedure
1. If the realignment process is running and the wrong paper is loaded, press the Cancel key on
the front panel.
Do not print if the realignment process has been canceled. You can restart the alignment with
the Image Quality Maintenance menu procedure.
2. Load the paper you wish to use, see
Paper handling on page 24. You can use a roll or cut sheet,
however, it must be A3 landscape or larger (420 by 297 mm). Photo paper is recommended for
the best results.
NOTE: If you are using an A3 cut sheet, ensure it is loaded so the larger side feeds into the
printer.
Do not use transparent or semi-transparent paper to align the printheads.
3. Remove and re-insert all the printheads, see
Remove a printhead on page 110 and Insert a
printhead on page 112. This starts the printhead alignment procedure.
4. Ensure the transparent 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.
