CHAPTER 5 In Case of Trouble If image quality is poor
When nozzle clogging is not corrected [HEAD SELECT]
If nozzles cannot be unclogged, make setting so that the printer will not use the head(s) with clogged noz-
zles. However, this function is available for printing operation (including nozzle check) and cleaning; ink
filling function is applied to all the heads.
 The setting for the [HEAD SELECT] function can be made also by the MRL- III
command (QH). However, the command cannot select any of the heads for
which setting has been made by the [HEAD SELECT] function so that they are
not to be used.
