• Use the recalibration excel sheet for checking if the voltages need to be modified.

ALARIS30 (Maintenance)

If print quality is not satisfactory:

• run a pattern test (see below) to check for clogged nozzles.
  • try purging, and cleaning the head (see below). Purge multiple times. Really clean the head, make sure there is no residue.
  • As a last resort, play with the voltage. Try a higher voltage (say +5 than current, see weight test below). Save the current voltages for rolling back once we're done. Set a higher voltage, and do a weight test. Printing a patch might open up the nozzles. Nozzles might open up slowly, over multiple prints, so slowly reducing the voltage back to original would be a good idea. Run more than one weight tests at the convergence point to see if a steady state has been reached.
• run the head alignment test
• run a weight test. repeat until the voltages are good.
• Change the wiper blade
• clean the roller waste collector (check the user guide).
• change the roller knife assembly
• might be a UV lamp problem too? check the maintenance counters. see the UV lamp section below.
• Print a known reference model (biz card, key) to see if that prints properly.

Sample print

Pattern test

• tape half of a red paper (provided, stored in the box under the printer table) to the print tray
• select menu>wizards>pattern test
• the printer prints two vertical bars. support on the left, model on the right. see if too many nozzles are clogged. Too many == 4 in a row or 12 in total.

Purge

Weight test

• From menu>maintenance>Modes>Weight test
• Go online. The printer prints two patches: one with only model (right one), one with support (left one).
• Weigh them separately.
• From maintenance>calibration, record the current voltages
• Use the recalibration excel sheet for checking if the voltages need to be modified.
• repeat if needed.

• Head alignment test: run wizard. Check the user guide for details.
• Weight test: (see in the head maintenance section) for voltage calibration. Excel file: Alaris30_Adjustment_Ver11_Master.xls
• Pattern test: (see in the head maintenance section) check for clogged nozzles.

• Press Ctrl+Alt+m, a confirmation window pops up, hit ok with the keyboard, keep the mouse pointer hidden.

Powering up

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

Shutting down

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.

Print Head Maintenance

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

Head cleaning

• 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

Flushing the head

Shutting down the machine

• 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.

Replacements/Cleaning

Check the maintenance counters on the control app menu.

1. Waste bin:

2. Odor filter:

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):

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

Installation/Calibration

• Installation guide: DOC-04006_Alaris30Installation_3.pdf
• Transparency test: XY alignment, overall. Parameters page.
• Head alignment test:
• Weight test: for voltage calibration. Excel file: Alaris30_Adjustment_Ver11_Master.xls
• Pattern test: to see if nozzles are working
