=head1 NAME

B<showcartridges>, B<hidecartridges>, B<headalign>, B<headclean> - Lexmark printer management commands

=head1 SYNOPSIS

  showcartridges
  hidecartridges
  headalign
  headclean

=head1 DESCRIPTION

=over 4

=item B<showcartridges>

Expose the print cartridges by moving the print carriage to the left.
This enables the cartridges to be installed or changed.  Application:
5xxx and 7xxx.

=item B<hidecartridges>

Hide the print cartridges by docking the print carriage.  This should
be called after issuing I<showcartridges> and changing a cartridge.
Application: 5xxx and 7xxx.

=item B<headalign>

Print the head alignment pattern.  This should be run whenever a
cartridge is changed.  Four patterns are printed.

=over 4

=item B<A>

This pattern displays the relative horizontal alignment of the black
and colour heads.  Use the best aligned number as the value for the
I<AlignA> argument to Ghostscript for the Lexmark 5000.

=item B<B>

This pattern displays the relative vertical alignment of the black and
color heads.  Use the best aligned number as the value for the
I<AlignB> argument to Ghostscript for the Lexmark 5000.

=item B<C>

This pattern displays the bi-directional alignment characteristics of
the black cartridge.  Not used by the Ghostscript driver.

=item B<D>

This pattern displays the bi-directional alignment characteristics of
the colour cartridge.  Not used by the Ghostscript driver.

=back

Application: 5000.  Possibly others.

=item B<headclean>

Prints ink-intensive patterns designed to clear clogged nozzles.
Application: 5000.  Possibly others.
