Correcting a Bad Nozzle Check Condition
1.
If you are unsatisfied with a nozzle check, first run a head clean. Perform a head clean from
the device properties dialog box in the Queue or to perform the head clean from the printer,
hold
for 5 seconds. After the head clean, run another nozzle check.
2.
Check for weeping ink. Look at the bottom of the Print Head to determine if either there is ink
weeping (dripping) from the print head or if no ink is flowing.
Use the up arrow to raise the print engine to its maximum height. Press
to unlock the
print head carriage. When it has stopped moving, manually move it to the center of the
shaft.
a.
Wipe the bottom of the print head with an alcohol wipe so it is clear of ink.
b.
Check the bottom of the head after 5 minutes.
c.
If you see lines of ink form on the print head, remove the cartridges and reseat
the filler caps. Turning the filler cap as you seat it will help it to install more
easily and ensure a tight fit. Reinstall the cartridges and repeat step a. If the
cartridge continues to weep, replace it.
d.
Press
to return the print head to its normal position. Do one print head
cleaning cycle and then a nozzle check.
3.
Check for no ink flow. Check that ink is flowing from the cartridge.
1.
If necessary, press
to return the print head to its normal position.
2.
Remove the filler cap on the cartridge (color) that has the bad nozzle check. This will allow
more ink flow through that head.
3.
Do 2 print head cleaning cycles. Replace the cartridge filler cap. Do a nozzle check. If this
doesn't give a good nozzle check then proceed to Clear a Clogged Nozzle for the Print Head.
Clear a Clogged Nozzle for the Print Head
1.
While running a head clean, inspect the capping station caps to be sure that they
are filling with ink. If the caps do not fill, clean the gasket on the capping station
with a swab. If this doesn't resolve the ability of the capping station to seal, the
capping station should be replaced. DCS recommends replacing the capping
station every 3 months.
2.
Discard the current set of filling syringes, needles and cartridges being used for the
color which is not achieving good nozzle results. Using a new filling needle and
syringe, refill a new cartridge with ink and reinstall in the printer. One or two
cleaning cycles may be needed at that time. Perform a nozzle check again.
3.
Print a large square (approximately 6" or 150mm) image of the color that does not
exhibit a proper nozzle test result. This image may need to be printed several
times to eliminate air bubbles trapped in the head.
4.
If proper nozzle check output is not achieved at this time, contact DCS Technical
Support or your local dealer.
