8.3. Weekly Maintenance
The weekly maintenance combines different small handlings, and a storage procedure:
- Check the state of the “Purge” and “Home” station Grid, and remove eventually
cured ink off the grid and out of the underneath tray. The grid itself can be taken out
of the tray to have easy access to the tray. The tray at home position does not have a
drain pipe, so liquid ink in the tray has to be removed with an absorbing paper or
cloth. Use a filling-knife or a wide screwdriver, to cut off the cured ink that’s on the
ribs.
- 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 or aceton.
(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 flush the 4 right heads (Lc, Lm, W1, W2) and close them,
and in the second stage, flush the remaining 4 left heads (K, C, M, Y).
- Finally, open the 4 right heads again, and flush 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 “-.036”
- 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 pulled forwards and an absorbing paper or cloth onto the grid.
- 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)
