Servicing the Printheads
The Printhead Service selection in the Image Quality menu lets you:
■ align the printheads
■ refill the printheads from the ink reservoir
■ select the frequency that you check the printhead for nozzle failures.
The three selections in this menu are described in the following sections.
Aligning Printheads
The Align now selection causes the printer to align the printheads immediately, or if
an image is being printed, as soon as the current print job is done. The alignment
procedure requires a minimum media size of A3 or B-size.
The printer will automatically perform an alignment when printheads are re-seated
or the media type has been changed. You can use this feature if the image quality
print indicated an alignment error.
Refilling Printheads
The Refill now selection causes the printer to immediately refill the printheads.
Normally, it is not necessary to use this feature since the printer automatically refills
the printheads with ink whenever it detects that there may not enough ink remaining
in the printheads to print an E-size image. An example of when you might want to
refill the printheads is before printing a long-axis print, to ensure that the printhead
will not need to stop and refill in the middle of the print.
