xTool O1 Omni Ink Guide: Ink Sets, Cartridges, Maintenance Tanks & Reorders

When comparing the xTool O1 Omni Printer, the machine configuration is only part of the buying decision. Ink, maintenance tanks, pretreatment, DTF film, and replacement consumables all affect how your printer performs over time.

The O1 Omni is available in multiple configurations, and each one uses a different ink setup. That means the right ink set for a Single UV Edition is not the same as the right setup for a Dual UV Edition or DT + UV Edition.

This guide breaks down which O1 Omni ink products fit each workflow, what to keep on hand for reorders, and which maintenance items support more consistent production.

Start Here: Your O1 Omni Edition Determines Your Ink

Before ordering ink or replacement cartridges, confirm which O1 Omni configuration you own or plan to buy:

  • Single UV Edition – UV printing for rigid materials using CMYK, white, and varnish.
  • Dual UV Edition – expanded UV printing with specialty channels such as rigid white, flexible white, fluorescent red, and fluorescent yellow.
  • DT + UV Edition – combines UV printing with DT fabric ink workflows for apparel and fabric applications.

If you are still comparing configurations, start with the xTool O1 Omni Printer product page before choosing your ink set.

Best First Purchase: Essential Ink Set for O1 Omni Printer

The easiest way to avoid ordering the wrong combination of cartridges is to start with the Essential Ink Set for O1 Omni Printer. This product is organized by edition so you can match the ink set to the machine configuration you select.

For Single UV Edition

The Single UV setup is built for standard UV printing on compatible rigid materials. The essential ink set for Single UV includes the core UV colors needed for everyday hard-goods personalization.

  • UV White
  • UV Black
  • UV Magenta
  • UV Yellow
  • UV Cyan
  • UV Varnish
  • UV maintenance tank and used ink cartridge support

This is the best fit for shops focused on acrylic, wood, metal, glass, ceramic, signage, gifts, and other hard goods.

For Dual UV Edition

The Dual UV setup adds more advanced UV capability for customers who want specialty effects and expanded material workflows. In addition to standard UV colors, this configuration can use additional UV channels for specialty output.

  • Standard UV CMYK ink
  • UV White
  • UV Varnish
  • Rigid White
  • Flexible White
  • Fluorescent Red
  • Fluorescent Yellow
  • Additional UV maintenance tank and used ink cartridge support

This is the better fit if your business wants more premium UV effects, fluorescent accents, flexible material capability, and expanded hard-goods production.

For DT + UV Edition

The DT + UV setup is the broadest configuration because it supports UV printing plus fabric-focused workflows. This edition uses both UV ink and DT fabric ink, so the starter consumables are different from the UV-only editions.

  • UV CMYK ink
  • UV White
  • UV Varnish
  • DT Fabric Cyan
  • DT Fabric Magenta
  • DT Fabric Yellow
  • DT Fabric Black
  • DT Fabric White
  • UV and DT maintenance tank support

This is the best fit for customers who want to print both hard goods and fabric products from one O1 Omni ecosystem.

Individual UV Ink Cartridges for Reorders

After your starter ink set is installed, reorders are usually handled by replacing individual colors as needed. For standard UV printing, start with the UV Standard Ink Cartridge for O1 Omni Printer.

Common UV standard cartridges include:

  • UV-C Cyan Standard Ink Cartridge
  • UV-M Magenta Standard Ink Cartridge
  • UV-Y Yellow Standard Ink Cartridge
  • UV-K Black Standard Ink Cartridge
  • UV-W White Standard Ink Cartridge
  • UV-V Varnish Standard Ink Cartridge

UV ink is used for hard goods, rigid substrates, decals, varnish effects, and other compatible UV printing workflows. Keeping replacement CMYK, white, and varnish cartridges available helps reduce downtime when production volume increases.

UV Specialty Ink Cartridges for Dual UV Workflows

If you have the Dual UV configuration, you may also need specialty ink channels beyond standard CMYK, white, and varnish. These are available through the UV Specialty Ink Cartridge for O1 Omni Printer.

Specialty UV cartridge options include:

  • UV-W Hard White Large Ink Cartridge
  • UV-W Soft White Large Ink Cartridge
  • UV-FR Fluorescent Red Standard Ink Cartridge
  • UV-FY Fluorescent Yellow Standard Ink Cartridge

These options are most relevant for customers using the Dual UV edition for specialty effects, fluorescent details, flexible white workflows, or premium UV applications.

DT Fabric Ink Cartridges for Apparel and Fabric Workflows

If you choose the DT + UV Edition, you will also need DT fabric inks. Replacement DT fabric cartridges are available through the DT Fabric Ink Cartridge for O1 Omni Printer.

DT fabric cartridge options include:

  • DTG-C Cyan Standard Ink Cartridge
  • DTG-M Magenta Standard Ink Cartridge
  • DTG-Y Yellow Standard Ink Cartridge
  • DTG-K Black Standard Ink Cartridge
  • xTool Selected DT Fabric Ink - White

DT fabric ink is used for apparel and textile workflows, including DTG-style printing and DTF-style production. If apparel is part of your business plan, keeping DT white ink available is especially important because white ink is a major part of many garment workflows.

Maintenance Tanks: Small Parts That Matter

Ink is not the only consumable to plan for. The O1 Omni also uses maintenance tanks and waste ink cartridges to support printhead care, cleaning cycles, and ongoing operation.

For UV workflows, review the xTool Selected UV Maintenance Tank for O1 Omni Printer. For DT workflows, review the DT Fabric Moisturizing Liquid & Waste Ink Cartridge Kit for O1 Omni Printer.

Why maintenance tanks matter

  • They support printer maintenance routines.
  • They help manage moisturizing liquid and waste ink.
  • They should be replaced when full, depleted, or prompted by the printer workflow.
  • They help reduce downtime when kept on hand as backup consumables.

If you print regularly, keep at least one spare maintenance tank or waste ink-related kit available so you are not forced to pause production while waiting for a reorder.

Maintenance Kits for UV and DT Printheads

The O1 Omni includes automated maintenance support, but owners should still keep the proper cleaning kits available for routine care and troubleshooting. UV and DT maintenance items should not be mixed between printheads.

UV Maintenance Kit

The UV Maintenance Kit for O1 Omni Printer is intended for UV printhead and UV workflow maintenance. It supports tasks such as cleaning the printhead area, ink residue removal, platform cleaning, and routine maintenance.

DT Maintenance Kit

The DT Maintenance Kit for O1 Omni Printer is intended for DT printhead care. This is especially important for customers using the DT + UV edition for garment and fabric workflows.

Never use the DT maintenance kit on the UV printhead, and never use UV maintenance tools on the DT printhead unless xTool documentation specifically instructs otherwise.

Ink Pad, Scraper, and Air Filter Reorders

Some O1 Omni consumables are not ink cartridges, but they still support print quality and machine care.

Ink Pad & Scraper Replacement Kit

The Ink Pad & Scraper Replacement Kit for O1 Omni Printer supports the printer maintenance area. These parts help manage ink residue, waste ink collection, and printhead cleaning routines.

Air Filter

The Air Filter for O1 Omni Printer is another reorder item to keep in mind, especially for shops running frequent UV printing or longer production sessions.

These parts are easy to overlook, but they become important when you want to keep the printer ready for repeatable production.

Pretreatment Solutions for DT Fabric Printing

If you plan to print apparel or fabric items with the DT + UV edition, pretreatment can be part of the workflow. Pretreatment helps improve ink adhesion and print performance on fabric.

As a simple rule, color ink pretreatment is typically associated with light-colored garment workflows, while white ink pretreatment is commonly used when printing on darker garments that need a white ink base. Always follow xTool’s workflow guidance for your fabric, artwork, and print mode.

UV Primer Wipes and DTF Film

For hard goods, glass, ceramic, decals, and transfer workflows, two supporting consumables are especially useful:

Primer wipes are useful when preparing certain hard surfaces like glass and ceramic. DTF film supports transfer-based workflows where the finished design is applied to the final product after printing.

Recommended Reorder Checklist

To avoid production delays, keep a small reorder plan for the consumables that match your O1 Omni edition.

Single UV customers should monitor:

  • UV CMYK cartridges
  • UV white cartridge
  • UV varnish cartridge
  • UV maintenance tank
  • UV maintenance kit
  • Ink pad and scraper replacement kit

Dual UV customers should monitor:

  • UV CMYK cartridges
  • UV white and varnish cartridges
  • Rigid white and flexible white cartridges
  • Fluorescent red and fluorescent yellow cartridges
  • UV maintenance tanks
  • UV maintenance kit

DT + UV customers should monitor:

  • UV CMYK, white, and varnish cartridges
  • DT fabric CMYK cartridges
  • DT fabric white ink
  • DT and UV maintenance tanks
  • DT maintenance kit
  • UV maintenance kit
  • Pretreatment solutions
  • DTF film if running transfer workflows

How Often Should You Reorder?

There is no single reorder schedule that fits every shop. Ink and maintenance use depends on your print volume, artwork coverage, white ink usage, cleaning frequency, material type, idle time, and production workflow.

A shop printing small hard-goods orders a few times per week may use consumables very differently than a business running daily apparel, decal, and UV production. The best approach is to track usage during your first few weeks of real production and set reorder points before cartridges or tanks run low.
