A
fter the ink charge print out a nozzle check to see if all the colours are
printing correctly. If they are, you are set to go. If not, perform a head
clean and test the nozzle check again. You should see an improvement on
the next nozzle check.
I
f still not perfect you can perform one or two more head cleans ( do not
overdo this exercise ) until you get a good nozzle check.
O
ccasionally a printer will stubbornly refuse to print a perfect nozzle
check after a couple of head cleans. There can be a number of reasons for
this including the fitting of a dye sublimation system for the first time or a
printer being left for a long time without running any prints. If you have
to run more than a couple of head cleans be careful not to overdo it. Run
up 5 head cleans but keep checking the nozzles after each one. If the
nozzle pattern improves dramatically but is not perfect leave the printer to
sit for at least 30 mins then check the nozzles again. Sometimes the nozzle
check has improved further still within wasting any more ink (and trying
your patience). If there are only a couple of nozzles missing try a print to
see if this kicks in those last couple.
F
urther head cleans when the nozzle check is almost perfect can often
result in the whole thing going backwards and the nozzle checks
becoming very poor.
