10.7.7 Checking and cleaning the pre-curing unit
The lamp modules of the precuring unit located beneath each print head
always have to be kept clean. If they become too dirty, not enough light can
be transmitted to the applied ink. As a result, the ink might not be properly
crosslinked and the different colors could run into each other.
Required aids:
Clean, solvent-resistant protective gloves (see Chap. 2.5.5)
Spotless cleaning cloth for print heads CSAT order no.:
FF100252100
Cleaning fluid suitable for the type of UV ink used
Notice
The print heads located next to the lamp modules of the pre-curing
unit are very sensitive! Therefore…
never touch their nozzle plates with your bare fingers
do not exert pressure on the nozzle plates
do not work with hard objects in the area beneath the print heads
therefore, remove bracelets and rings.
Non-compliance will result in the loss of all warranty rights!
The lamp modules of the pre-curing unit are not cleaned during the me-
chanical print head cleaning process, but rather, they can
– and must – be
cleaned by hand only. This is usually done at the same time as the manual
cleaning of the print heads, but it can also be done more often as needed
according to the following instructions.
In order to be able to check and clean the lamp modules of the pre-curing
unit, the entire print head unit has to be pushed back into its service posi-
tion.
>
Stop the printing process.
>
Wait until the printer has shut
down completely.
>
Open the middle door at the
rear of the printer.
