NOTICE: Failure to follow these instructions will result in the warranty being voided.

Daily Maintenance:

Check ink level in the ink bottle. If the bottle is empty (the message: INK LACK or EMPTY BOTTLE is shown on the terminal display), replace it.  In the systems with electromagnetic heads and the pump-based ink system, the ink bottle can be replaced while the printing operation is being performed. If a compressor system is used you need to stop the printing and depressurize the ink system – see section 2.3.5 Installing a new Bottle of Ink (or Replacing an Empty One).  After the machine has been switched off – wash outer parts of the print head, especially the nozzles and photodetector in order to remove any remaining ink.

Routine Maintenance:

Once a week (or more frequently, if required) – check the state of supply air filters (which remove water, oil etc.) and clean them, Every 1000 hours of operation – check the ink filter in the bottle. Use the ACTIVITY TIME command to check for how many hours the printer has run. The total number of run hours (hours: minutes) is displayed on the terminal. Replace the ink filter every 12 months.

If the printer is not to be used for a longer time (over 2 weeks), secure the print heads as described in section 7.1 Storing the Printer. NOTE! The use of sharp tools or improper fluid (solvent) to clean and wash the head may result in damage that is not covered by the warranty! Ink and cleaning fluid (solvent) can only be used, if supplied by the printer Manufacturer! Different ink types must not be mixed! THE FAILURE TO MEET THE ABOVE REQUIREMENTS SHALL RELEASE THE MANUFACTURER FROM ITS WARRANTY OBLIGATIONS.

Purging:

Removing Air from the Ink System Transport, manipulations to the ink system, or other reasons may result in accumulation of air within the print head. In consequence ink drops are not jetted from some or all nozzles. In order to remove air from the print head, follow the instructions below:

1. Set the ink pressure to its rating value.
2. Turn the nozzle outlets towards a dish (which can be used to wash the head, for example).
3. Press the rinse key “C” at the sloping part of the head housing. This will open all electromagnets within the head to release air bubbles, which will flow out together with the pressurized ink.
4. Continue the air removal process until regular and continuous ink jets start flowing out of each nozzle.
5. Release the rinse key.

The printer does not switch on:

• Check whether the outlet socket is energized.
• Check whether the power cord is plugged into the socket.
• Check whether the main switch (on the right-hand side of the printer controller) is in its ON position.

NOTE: Electronic protections are installed in the power supply in compliance with standards. There is no fuse that might be replaced by the user.

No overprints are made after the print command has been accepted:

• Check whether the print head, photodetector and possibly the shaft-encoder are connected to the printer properly (cable connectors need to be plugged in and screwed tight in the controller and the head).
• Check for proper settings of print parameters. If Generator=SHAFT, check whether the shaft-encoder axle rotates. If Text rpt. is not set to CONTIN., check whether moving objects are detected by the photodetector.
• Check whether the other print parameters are set properly.
• Check whether the ink system components are connected properly, the ink system is pressurized, and there is some ink in the ink bottle.

Clogged nozzles in the head:

• Follow the instructions below: Cut the air pressure off and wait until the ink pressure drops down to zero. Remove the distance holder for packages from the front part of the head. Unscrew four or six fixing screws on the nozzle plate and remove the plate carefully.
• If possible, wash the nozzle plate with solvent in ultrasonic bath. If the ultrasonic bath cannot be applied, leave the nozzle plate in solvent bath for about 10 minutes. Dry the plate. Make sure no paper fibers are left.
• Clear the nozzles with a tungsten wire carefully from the back to the front (The tungsten wire supplied by the manufacturer must be used only !!!).
• Fasten the nozzle plate with screws taking care not to damage rubber O ring or Hydroaccumulators.
• Install the slipper.
• Set the ink pressure to its rating value, switch the printer on, and remove air from the head system.

NOTE: The above operations need to be performed under strictly clean conditions. Do not leave any foreign objects under the nozzle plate. If the plate is fastened improperly, the nozzles may get damaged (ruby tip may break) or leaking may occur.
