Print Head Maintenance

$1300 each!! Not covered by warranty. To be replaced only by vendor engineers.

Head cleaning

Once a week.

• Run the head cleaning wizard. It will place the head assembly on top of the tray and lower the tray (“z axis”).
• Put the mirror on top of the tray to be able to see underneath the assembly where the heads are.
• Use 99% IPA to clean up the head. Remember to use a pair of gloves, IPA can irritate your skin.
• Spray IPA into the microfiber cloth
• Reach under the head and wipe from the middle to one end, don’t come back inward. Again start from the middle and wipe towards the other end. Do the same with the other head.
• Also reach the roller and clean it. Wipe and roll.

Aligning print heads

Once every 6 months, or sooner if quality suffers. Use the head alignment test wizard. It will print a number of lines with different head alignment on a transparent sheet. Use the magnifier glass to pick the best alignment.

Flushing the head

Only if the machine is not going to be used for months, flush the heads with the fill/flush wizard.

Shutting down

• Keep the machine running at all times. Close the control app to turn off the print head fans.
• Once a week, print the business card. If needed, shut down with the shut down wizard. Shutting down may require “voltage” recalibration.

Powering up

• Power on (switch in the back)
• Run the controller application "Alaris" from printer computer's desktop
• Reinitiate from controller app menu if the machine was shut down for more than 72 hours.
• Fill the head if not filled with fill/flush wizard from the menu.
• Turn the printer online by pressing the big red button on the controller application.

Replacements/Cleaning

Check the maintenance counters on the control app menu.

1. Waste bin:

Lives in the drawer, inside the cardboard box. Waste accumulates as you operate the machine. It needs to be replaces once >1.8 kg of waste has accumulated. Check the controller app, if the waste bar is red, replace it. Be careful not to twist the plastic bag inside. Open the cardboard box, hold at the neck of the plastic bag, and twist the pipe connector at the top. Put one of the supplied lids on the plastic bag. The waste is in liquid form, either cure it with UV or put it in the sunlight. Once the waste hardens, throw it in the garbage. Waste bags are free for the first year.

2. Odor filter:

Needs to replaced every 1 to 2 years, if needed. It is in a drawer in the back.

3. Model/support cartridge:

• MSDS (Material safety data sheet): msds_001.pdf

Each cartridge holds 1kg of liquid material. There are two model (square) and two support cartridges (rectangular) in the drawer. Once empty, replace. Replacements can happen while a print job is running without causing any interruption. The control app shows amounts left in the cartridges.

Replacements must be purchased in pairs. Vendor contact.

Toxicity: Liquid form is toxic. Inhaling is not a problem, touching might irritate the skin. Never touch your eyes with it or taste it. Wear gloves when handling the liquid form. Once cured it is not toxic.

Removing the current cartridge: Pull up vertically, the rubber membrane seals off the cartridge. Don’t touch the rubber membrane Top insertion. Don’t put force, just let it slide in position, and then vertically put it down for the needles to penetrate through the rubber membrane.

Expiration: Recommended shelf life: 4 months. There is an expiry date, best if used by then.

4. Wiper blade (head cleaner):

Lives in the top-left bay. Change it if it has dips on the rubber surface.

Wiper cleaning: once a week. Run the wiper cleaning wizard.

5. Knife:

If necessary. We have a spare.

6. Head:

see head maintenance above.

7. Computer parts:

The front cover comes off once the front screws are taken out from the top. Motherboard and other computer parts.

8. UV lamp:
