1 What is a vertical wall printer?

A vertical wall printer is a revolutionary machine that prints high-resolution designs directly onto wall surfaces. Eliminating the need for traditional paint or wallpaper, it provides an efficient, highly customizable solution for interior decorators, businesses, and homeowners.

This innovative device uses advanced software and premium UV ink to transform ordinary walls into stunning works of art.

2 How does the vertical wall printer work?

The machine uses a piezoelectric inkjet printhead to precisely spray UV-curable ink onto the wall. An attached UV lamp instantly cures (dries) the ink, making the print durable and immediately dry to the touch.

During operation, the machine moves horizontally on wheels or ground tracks, while the printhead carriage moves vertically, allowing it to seamlessly print large-format images.

3 What is included in the printer package?

Our standard vertical wall printer solution includes everything you need to get started:

  • 2.32m Print Height Setup: Includes the 12.2cm platform and two 110cm Y-axis vertical tracks.
  • Horizontal Tracks: 5 meters of rails for uneven surfaces.
  • UV Curing System: 2× UV LED lamps with a temperature control system.
  • Print System: 1× Epson printhead, 5× Ink tanks (180ml) with low-ink alarms, and 1× pump/cleaning motor kit.
  • Built-in Computer: 13.3-inch Touch Screen PC (8GB RAM, 256GB SSD) loaded with DXonJet Control Software and MainTop RIP Software (ICC profiles included).
  • Spare Parts & Tools: Complete assembly tools, 1× damper, 4× cables, fiber cable set, 2× extra ink tanks, 1× pump motor, and spare screws.
  • Support: Remote training via video call (or 3-day on-site training in China) + 12 months warranty with lifetime tech support.
4 Can the printer print 3D images on the wall?

Yes, it can create 3D effects in two distinct ways:

  • Visual Illusions: By printing well-designed images with artificial shadows and perspectives, the flat print appears three-dimensional.
  • Tactile Textures (2.5D): Because UV ink cures instantly and sits on the surface, we can repeatedly print layers of white ink in specific areas to build actual physical textures you can feel.
5 What type of ink does the wall printer use?

The VPJet series uses premium UV-curable inks imported from the USA under the brand name Nazdar.

Extensive real-world testing has proven these inks to be of exceptional quality and highly reliable, significantly reducing the risk of printhead clogging. As industry experts know, high-quality ink is the absolute best protection for your printer's nozzles.

6 What image formats are supported for printing?

The printer utilizes professional RIP software that supports popular image formats, including JPEG, PNG, TIFF, and PDF.

For the best results, we highly recommend using high-resolution images (typically 200 to 300 DPI). You can source these high-quality graphics from professional digital cameras, stock photo websites, or design software like Adobe Photoshop.

7 What is the lifespan of the machine?

At DXonJet, our philosophy is simple: "We build machines that print; we are not in the business of manufacturing spare parts."

The VPJet series is constructed with highly reliable industrial-grade components designed to last for years without major part replacements. Only standard consumables (such as ink, printheads, and ink tubes) will require periodic replacement due to normal wear and tear.

8 What are the main consumables?

The primary consumables for our vertical inkjet wall printers are:

  • UV Ink
  • Printheads
  • Dampers & Ink Tubes
  • Ink Tanks
  • Pump Caps
9 How do I maintain the vertical wall printer?

Maintenance is incredibly straightforward and primarily involves caring for the printhead and the UV lamp:

  • UV Lamp: Regularly wipe dust and stray ink off the UV lamp glass to ensure maximum curing power.
  • Printhead: Keep the printhead moist. If the ink inside remains stagnant for extended periods, it may dry and cause clogs. Performing regular test prints or using the software's automated cleaning cycle to flush fresh ink through the nozzles will keep it in peak condition. This automated process takes less than a minute.

Important: Do not use cleaning fluids for daily maintenance. Cleaning fluids are only for clearing heavy clogs, while moisturizing fluids are intended only for brand-new, uninstalled printheads. High-quality ink is the best daily lubricant for your printhead.

10 What is the maximum print size?

The standard VPJet series stands at 232cm, allowing for a maximum print height of 196cm. By installing an additional vertical extension pole (100cm), the printer can achieve a print height of up to 296cm. (The printing width is infinite, as you can continuously add horizontal ground tracks.)

When printing at heights exceeding 230cm, stability is crucial. We have reinforced the VPJet's support columns and equipped it with a heavy-duty solid aluminum base (weighing 23kg). As a result, the printer remains perfectly stable without any swaying, even when printing up to 300cm high.

11 Are wall printers made in China reliable?

We completely understand this concern. The reality is that the majority of cheap wall printers on the market are indeed unreliable, suffering from poor design, sub-par manufacturing, and non-existent after-sales support.

However, DXonJet is different. Our team has specialized exclusively in vertical wall printing technology for over 10 years. We engineer our machines with industrial-grade components and enforce rigorous quality control alongside comprehensive technical support. We have built a solid global reputation and are trusted by distributors worldwide.
