2. V-One Maintenance

2.1 Protect the nozzle

The golden rule of high quality dispensing is to protect the dispensing nozzle. If the nozzle tip is dented, bent, broken, or contaminated with dry ink, print quality will suffer. To ensure optimal performance, follow the guidelines below:

• Gently wipe the nozzle with a clean tissue to remove material build-up before and after use.

• Always store the dispenser with the tip cap on to prevent accidental damage.

• When removing the tip cap, twist to loosen and then pull straight away from the nozzle.

A clogged nozzle can be identified by either no or inconsistent material flow. A clogged nozzle can be the result of many factors including improper material storage, expired material, or a damaged nozzle.

Note: Do not try to clear the clog by force. This can puncture the piston in the cartridge. Before replacing the nozzle, be sure to inspect the clogged nozzle for damage and inspect the material cartridge for its expiration date.

2.2 Refrigerate the inks

If the inks were left out by accident, we recommend that you purge the fluid in the nozzle by manually turning the dispensing gear gently. If no fluid is coming out you must replace the nozzle.

The conductive ink and solder paste must be stored in a refrigerator or a cool place between 4-10°C (40-50°F), with caps on, to preserve their shelf life. The probe can be stored at room temperature.

2.3 Protect the probe

The probe is an essential accessory for dispensing. To ensure optimal performance:

• Do not drop the probe or attempt to disassemble it.

• Ensure the probe is in a safe place with the cap securely in place when it is not in use.

• Ensure the contact pads on the probe cap are clean. If necessary, use a cotton swab and use isopropyl alcohol to clean them.

2.4 Cleaning V-One

Wet conductive ink can generally be wiped off using a paper towel or tissue. If inks get on your skin, wash thoroughly with soap and warm water. Before handling the materials, be sure to refer to the material safety data sheets available at https://docs.voltera.io/docs/data-sheets.

Dried conductive ink that has not been baked can be cleaned by applying a small amount of isopropyl alcohol and rubbing with a paper towel.

Conductive ink that has been baked is much more difficult to remove. Apply isopropyl alcohol to a burnishing pad and rub vigorously. Repeat until the ink has been removed. Using sharp tools to remove the ink may result in damage to the surface below or injury.

V-One uses several limit switches for self calibration. To ensure optimal performance, clean these switches regularly with a cotton swab and isopropyl alcohol. Failure to do so may result in poor dispensing quality and broken nozzles. It is recommended to perform cleaning before starting a workflow to avoid calibration errors.

2.5 Transporting V-One

When moving V-One, do so by lifting by the base with two hands. Avoid lifting the machine by the bridge. For long distance transportation or shipping, it is recommended to store the V-One upright in the original packaging to avoid any damage during travel.

2.6 Replacement fuse

In the event of a blown fuse in the power inlet, contact technical support as a blown fuse may be a symptom of a more serious issue. Use the table below to select a suitable replacement.

	100-120 ACC	200-240 ACC
Ratings	5 A 250 ACC	3 A 250 ACC

Note: Be sure to disconnect the power cable from V-One before installing the replacement fuse.

2.7 Replacement power cable

Please check the product label on the back of V-One before using the table below to select a suitable replacement.

	100-120 ACC	200-240 ACC
Length	≥ 1.8 m	≥ 1.8 m
Ratings	> 250 V, > 10 A	> 250 V, > 10 A
Termination	C14 to plug type B	C14 to plug style F

2.8 Prepare the dispenser assembly

V-One comes with two identical dispensers for the two ink cartridges: conductive ink and solder paste. Be sure the dispenser’s plunger is fully retracted before assembling.

If the plunger is too far out it can push ink out during assembly.

1. Remove the dispensing cap from the cartridge sheath. Remove the green lids from the conductive ink cartridge.

2. Insert conductive ink cartridge into the sheath with the ink level visible through the viewing window.

3. Twist the dispensing unit back into the cartridge sheath.

4. Carefully twist the nozzle onto the end of the cartridge.

2.9 Run the software

Note: V-One may require a firmware update on startup. Do not disconnect or turn off V-One during the firmware update.

1. Connect V-One to your computer with the provided USB cable.

2. Turn on V-One by pressing the power button.

3. Open the desktop application software.
