Maintenance Schedule ITS6
Every 2 hours
All print heads must undergo a standard or intensive cleaning very two
hours at the latest (see Chap. 10.7.5.1 Mechanical cleaning of the nozzles
Daily
At the end of the shift, all of the print heads must first undergo a standard
cleaning and then be cleaned by hand.
Move the print head unit to service position, check the wipers for print head
cleaning for dried up ink residues and clean them manually.
The wipers must be straight and sharp-edged. They must not show any
cracks or foreign bodies.
Each wiper must be aligned in parallel to the upper edge of the related
clamping plate.
Replace wipers if necessary.
At the end of the shift, check all of the LED strips of the pre-curing unit for
any dirt and clean if necessary.
Check inlet suction. Remove any dirt
Check all guide rollers for spotlessness, clean if necessary.
Check the adhesive film of the printing substrate cleaning module on a
regular basis. If heavily soiled or lacking adhesive power, tear off one layer
of the adhesive foil.
Move the print head unit into the service position, check the wipers used
for cleaning the print heads for areas of dried-on ink and clean by hand
(see chap.10.7.5.2
„Manual cleaning of the print heads”.). The edges of
the wipers
have to be straight and sharp and shouldn’t have any cracks or
especially any foreign objects on them. Furthermore, the cleaning edge of
each wiper must be aligned parallel to the upper edge of the clamping
plate. Replace wiper if necessary, see chap. .10.6.3
Move back the print head unit into the service position and check the roll-
ers of the printing table and the sheet below for spotlessness. Clean with
cleaning fluid or acetone if necessary.
Check to see whether the entire print image is narrower than the substrate
to be processed and that it is positioned entirely on the web so that no ink
is sprayed alongside the substrate onto the printing table without being
fixed there. Furthermore, when the printing table is soiled with ink, the
guide rollers behind the printing table should be checked for soiling also.
Check the glass shields of the UV lamps for soiling. Completely remove
heavier grime deposits using a special cleaning pad (order no.
ZE1010-75
)
if necessary.
Check the rubber rollers of the web tension controller and the friction drive
for soiling. If necessary, clean with isopropyl alcohol.
Check the electrodes of the two substrate dischargers for soiling. Remove
