8.3. Weekly Maintenance
The weekly maintenance combines different small handlings, and a storage procedure:
- Clean the “Purge” and “Home” station Grid.
Use a filling-knife or a wide screwdriver, to cut off
the cured ink that’s on the ribs.
(the “Home” grid can be taken out to remove the particles)
- Check the Purge station waste box and clean it, if hardened ink is present.
- Check the waste ink tank underneath the printing
table; dispose the ink according to local government
regulations. (Also see chapter 5.6.)
- Clean the “encoder” strip with alcohol.
(Situated upfront on the main beam)
ENGINE STORAGE AT THE END OF THE WEEK:
- Move the carriage to the Purge position.
- Flush cleaning solution through the heads:
- First purge the 4 right heads (Lc, Lm, W1, W2), close them,
and in the second stage, purge the remaining 4 left heads (K, C, M, Y).
- Finally, open the 4 right heads again, and purge all 8 heads together now.
By doing so, you’ll have the most optimal cleaning pressure.
- Switch all heads, and the Solution valve back to “I”.
- Set the Neg. Vacuum Pressure to “0”, leave the system for 1 minute
(Ink will now start dripping out the heads)
- Empty the sub-airtank by opening the tap (use a tube into a PE-bottle)
(Sub-airtank is located at back of carriage)
- Restore the Neg. Pressure back to “-.034”
- Perform a Large Purge
- Clean the Head Base Plate with a cloth
- Clean the heads with a fiber-free cloth.
- Check the nozzle’s on “weeping” or with a Jet Test.
- If all nozzles are present, the engine can be left in the Purge Position,
with the Grid pushed backwards.
- Replace the towels in front of the Purge grid, and check/clean the whole Purge
station environment, the front of the UV-lamps might need some cleaning too.
- Clean the Quartz plate of both UV-lamp houses with alcohol. (underside of lamps)
