Most technicians print their first client-ready nail within 15 minutes of unboxing the O2nails X11 Plus. This guide walks through the complete workflow from setup to finished nail — power on, prep, print, seal — so you know exactly what to expect and can train your staff with confidence.

What You’ll Need
- O2nails X11 Plus printer (powered on, ink cartridges installed)
- White or light-colored base coat (applied and fully dry)
- Top coat (for sealing after printing)
- Design selected on the touch screen or imported via Wi-Fi/USB
- PG4 print gel and nail guard stickers (included with the machine, restocked as consumables) to protect cuticles and prime the surface
- A UV/LED lamp (the included card LED lamp works for touch-ups) to cure the base and top coats
Step 1: Power On and Initial Setup
Connect the X11 Plus to power using the included AC adapter. Press the power button and wait for the 10.1" touch screen to load — this typically takes 20–30 seconds. No phone, laptop, or external app is required.
On first use, connect to your salon’s Wi-Fi network via the Settings menu. This enables design library updates and custom design imports going forward.
Step 2: Prepare the Client’s Nails
Nail preparation is the most important factor in print quality. Follow these steps:
- Complete the base manicure service as normal (shape, buff, clean)
- Apply a white or light-colored base coat — this is essential for accurate color reproduction
- Allow the base coat to dry completely before printing. A tacky or wet base coat will smear and ruin the print
- Do not apply top coat before printing
Pro tip: A UV/LED-cured gel base coat gives the most consistent surface for printing and dries faster than air-dry polish.
Step 3: Select or Import a Design
On the touch screen, navigate to the design library. You can:
- Browse pre-loaded designs — thousands of patterns organized by category (florals, geometric, seasonal, photographic, etc.)
- Import a custom design via Wi-Fi — use the O2nails companion app to send a client-supplied image directly to the printer
- Import via USB — save JPG or PNG files to a USB drive and plug into the printer
Select the design and confirm. The printer will display a preview on screen before printing begins.
Step 4: Position the Finger
Place the client’s finger into the nail slot on the front of the printer. The sensor will automatically detect the nail position and width — no manual calibration needed for most nail sizes.
- Ask the client to keep their finger still and flat during printing
- The finger rest is adjustable — use it to stabilize the hand for clients who have difficulty holding still
- For very small or very large nails, use the manual adjustment option on screen to fine-tune the print area
Step 5: Print
Press the print button on screen. The print head will pass over the nail and complete most designs in 20–30 seconds.
Do not move the finger during printing. The printer will signal completion with a sound or on-screen notification.
Step 6: Inspect and Repeat
After each nail, inspect the print before moving to the next finger. Common issues and quick fixes:
- Smearing or blurring — base coat was not fully dry; allow more drying time
- Color looks washed out — base coat is too dark; use a lighter or white base
- Print misaligned — finger moved during printing; reprint on that nail
- Ink not adhering — nail surface may have oil residue; clean with a lint-free wipe before reprinting
Repeat for all 10 nails. A full set typically takes 5–8 minutes of total print time.
Step 7: Apply Top Coat
Once all nails are printed and the ink has set (allow 30–60 seconds after the final nail), apply a clear top coat to seal and protect the design. A UV/LED gel top coat provides the best durability and finish.
The printed design is water-resistant once sealed and will last as long as the base manicure.
Maintenance: Keeping the Printer in Top Condition
- Daily: Run a print head cleaning cycle at the start and end of each shift (accessible from the Settings menu)
- Weekly: Wipe the exterior and nail slot with a dry lint-free cloth
- As needed: Replace the cartridge when the on-screen indicator shows low ink. The X11 Plus uses the SM10 high-capacity cartridge (up to 1,000 nails per cartridge); the M1 model uses FM10. Order genuine SM10 / FM10 ink cartridges and print gels — using authentic O2nails cartridges prevents print head damage.
Training New Technicians
The X11 Plus is designed for low training overhead. Most technicians are comfortable with the full workflow after 2–3 practice sessions. We recommend:
- First session: practice on nail tips (not clients) to get comfortable with positioning and timing
- Second session: first client with a simple design (single color, minimal detail)
- Third session: full design library and custom imports

X11 Plus vs X11: What's the Difference?
If you're deciding between models, here's a quick comparison based on O'2NAILS official specifications:
| Feature | X11 Plus (Desktop) | X11 (Mobile) |
|---|---|---|
| Screen | 10.1" touch screen — standalone, no phone needed | Smaller screen, requires O'2NAILS app on phone for full control |
| Form factor | Desktop unit (3.5 kg, 175×190×448 mm) — sits on nail station | Compact, portable — easier to carry between locations |
| Operation | Touch screen with built-in Android OS — browse, preview, print all on device | App-controlled via Bluetooth/Wi-Fi from smartphone |
| Ink cartridge | SM10 — up to 1,000 nails | FM10 — same print quality, smaller capacity |
| Best for | Fixed salon stations, high-volume nail bars, walk-in studios | Mobile nail techs, home studios, trade shows and events |
Both models print at 2400 DPI and support the same design library. The X11 Plus is the better choice if you have a fixed station and want fast, phone-free operation; the X11 suits mobile technicians who travel between clients.

Frequently Asked Questions
Why won't the X11 Plus print?
Check four things in order: the power connection and the power switch on the back, whether the correct printer is selected in the O'2NAILS app, the connection between the tablet and the machine, and whether a nail tip or practice finger is loaded under the print head. If the screen shows an error code, restart the machine and re-pair the app before trying again.
How do I load the nail tip correctly?
Open the finger holder, place the nail tip flat against the bracket with the nail surface facing up, and push it in until it sits securely. The surface must be level — a tilted tip causes blurry prints or contact with the head. Close the guard before starting a print.
How long does an ink cartridge last?
Cartridge life depends on print coverage and design complexity; the app shows a low-ink reminder when it is time to replace it. When prints fade or streak, swap in a fresh authentic O'2NAILS cartridge. Third-party ink can clog the print head.
Why are prints blurry or misaligned?
The usual causes are an unlevel nail surface, oil or dust residue on the nail, or a print head that needs cleaning. Wipe the nail with the recommended prep before printing, make sure the tip sits flat, and run the head-cleaning function in the app. Do not move the machine while it is printing.
How should I clean and store the machine?
After each day of use, wipe the exterior and finger holder with a soft dry cloth, run the automatic head-cleaning cycle, and keep the cover closed when the machine is idle. Keep it in a dry, dust-free place away from direct sunlight, and follow the maintenance schedule in the user manual.
