(3) Manual micro-purge followed by a manual dry clean
As detailed in steps 1 & 2 above, force the manual micro-purge followed
by a dry wipe of the nozzle face.
Repeat this process a number of times until you see an improvement in
the nozzles being fired. If this does not recover the nozzles and they are
still missing then the cartridge needs replacing, probably due to
irreversible damage to the nozzles
Banks of missing nozzles
In some instances whole swathes of nozzles are missing, see the images below.
