Capping station failing
sooner than 3 months
DCS_Direct_Jet_1024UVHS_Maintenance_Troubleshooting_Guide_1.2.docx
During Normal Operation the capping
station should last 3 months on average.
Normal operation is running the printer 8
hours a day, 5 days a week.
Why does the capping station fail? The
reason the capping station fails is because
the solvents in the ink and cleaning solutions
dry out the rubber gasket that is used to seal
against the print head. This gasket is used to
create a vacuum that pulls air and dried ink
from the print head nozzles.
Premature Failure of the

Capping Station

There are a number of items that can
accelerate the failure of the capping station:
2. Failing to put the filler cap tightly
on the cartridge. This will allow an
excessive amount of ink to flow through
the nozzle and into the capping station.
3. Filling the cartridges while they are
still in the Print Head. This should
never be done because when the filler
cap on the cartridge is removed, the
valve on the bottom of cartridge is still
open. This will allow an excessive
amount of ink to flow through the
nozzle and into the capping station.
This will continue even after the filler
cap is replaced and will cause the ink to
continue to drip through the head.
Another concern is that the inks are
conductive and if spilled can damage
the electrical connection in the print
head.
4. If the cap in the capping station is
mispositioned. The cap in the capping
station is spring loaded and should float
to the level of the print head during
cleaning. If the cap is pushed out of
position by cleaning with a swab or
some other means, it will not seat
against the print head properly and not
operate correctly.
