Static electricity is more than just a hair-raising experience; it’s a real issue in sublimation printing. This invisible menace can be particularly pronounced in winter or high-temperature conditions. The dryness caused by heating systems or arid indoor climates can exacerbate static build-up, especially around materials like synthetic fibers and carpets. So, why is this a problem for your fedar sublimation printer? The static electricity generated can interfere with the printing process and affect the final output.

The build-up of static electricity can lead to various print quality issues such as ink breakage, ghosting, and misalignment during the sublimation printing process. If left unchecked, high levels of static electricity can even pose a threat to the print head’s integrity, causing issues like ink sticking and potential hardware damage. In extreme cases, static electricity can reach voltages of 6-10V on digital printers, a level that’s as harmful as it sounds!

Grounding Your Sublimation Printer

Fear not, a viable solution to the problem exists. By grounding your sublimation printer correctly, you can thwart these electrostatic reactions while ensuring the safety of your printer components. When a printer is correctly grounded, it can drain away static charges, effectively eliminating static buildup around the printer head.

Grounding, however, is more complex than merely plugging in a wire. It’s vital to select an appropriate grounding wire and install it correctly to achieve effective grounding with the chosen ground wire.

Choosing the Right Ground Wire

Grounding isn’t a task for just any wire. For successful grounding of a sublimation printer, the ground wire must be a single, uninterrupted piece that maintains solid contact with the machine. This ensures that the static charge has a clear path to the ground, reducing the chance of electrostatic reactions.

Moreover, the size of the ground wire for a sublimation printer must be determined by the printer’s electrical requirements, adhering to electrical codes like the NEC (National Electrical Code). This ensures that the wire can handle the electrical load of the printer, preventing potential safety hazards.

Installing the Ground Wire

The installation process of the ground wire is equally important as its selection. The first step involves using an approved grounding rod set, which includes a rod, clamp, and conductor. This set should be certified by a group like Underwriters Laboratories to ensure its safety and effectiveness.

Next, to install a ground rod, follow these steps:

  1. Dig a hole 2-4 feet deep for the rod.
  2. Drive the rod into the ground using a hammer, drill, or driving tool until it’s fully inserted.
  3. Connect the ground rod to the building’s electrical system using a 4-gauge copper grounding electrode conductor and a ground rod clamp.
  4. Route the grounding electrode conductor to the building’s electrical panel.
  5. Connect the grounding electrode conductor to the ground bus bar where ground and neutral wires are located.

The grounding contact for a sublimation printer should be established using a copper plate welded well, with a copper wire buried in moist soil 1.5 meters below ground, and treated with saltwater.

Optimizing Your Print Shop Environment

Grounding is just one piece of the puzzle. To tackle static electricity effectively, it’s essential to also optimize your print shop environment. Regulating humidity and temperature can go a long way in reducing static build-up, thereby protecting your printer and ensuring consistently high-quality prints. Learn how to resolve issues such as lines being printed by your sublimation printer.

Proper Humidity Control

Humidity control proves highly effective in mitigating static electricity. It’s essential to maintain a relative humidity between 40% and 60% around the sublimation printer to diminish static build-up and preserve print quality. But how can you control humidity in a print shop?

The answer lies in industrial humidification systems, which can effectively eliminate static electricity. These devices help mitigate static electricity by allowing the moisture in the air to conduct electricity and neutralize the static charge. However, just having a humidifier isn’t enough. Regular inspection and maintenance of the humidifier are key to ensuring it performs optimally, consuming the appropriate amount of water to maintain the right humidity levels for static prevention.

Regulating Indoor Temperature

Stable indoor temperature while operating the sublimation printer is another critical element in controlling static electricity. This can be achieved through the use of an air conditioner, which also assists in controlling humidity levels.

During colder months, using a heater can help maintain an optimal temperature for printing processes and ink management, countering static electricity. On the flip side, venting heat from equipment like conveyor dryers is crucial to prevent a print shop’s temperature from becoming too high, which can increase static build-up.

Anti-Static Measures for Sublimation Printers

Beyond environmental control and grounding, you can also implement other anti-static measures to safeguard your sublimation printer. Some tools you can use include:

  • Anti-static sprays[1]
  • Ionizers
  • Non-conductive mats
  • Guards

These tools can help neutralize static charges and protect your inkjet printers’ head from static-induced damage.

Anti-Static Brushes and Tools

Anti-static brushes are a valuable tool in your anti-static arsenal. These brushes can be used on universal flatbed printers to tackle issues related to static electricity. Static elimination devices, such as these brushes, can be used to address static electricity in the print environment.

But brushes aren’t the only tool at your disposal. An ionizing wand can also protect operators from shocks due to static electricity. In addition, static elimination tinsel or similar devices can be attached to the printer to help control static as the media moves through during printing.

Conductive Ink Solutions

The choice of ink for your sublimation printer can also contribute to static electricity prevention. Conductive inks with higher viscosity have inherent anti-static properties that can benefit the sublimation printing process. Heavier ink droplets created by inks with increased viscosity are less prone to static charge interference, ensuring more accurate placement on substrates.

By employing inks with a higher viscosity, you can reduce the electrostatic effect, which is particularly troublesome in sublimation printing. This way, even marginal static electricity is less likely to disrupt the ink drops ejection and placement, enhancing the overall print quality.[2]

Preventing Material Build-Up

Avoiding material buildup is another crucial factor in mitigating static electricity in sublimation printers. Static electricity leads to dust build-up and improper ink manipulation, and it can cause cling of substrates, resulting in the contamination of print material and flawed final prints.

Using non-conductive guards, separating workstations, and employing static eliminators like brushes, wands, or bungees can help prevent static electricity and reduce material accumulation. Additionally, work surfaces should be maintained using fabric softeners or wipes that don’t interfere with printing materials.

Regularly cleaning the printer’s paper feed rollers with isopropyl alcohol can also help decrease static cling, preventing debris from sticking and potentially clogging the printer’s nozzles.

Maintaining Your Printer for Reduced Static

As with any machinery, regular maintenance is required for your sublimation printer to function optimally, particularly for reducing static. Regular printer maintenance is essential to minimize dust inside the printer, reducing the likelihood of static build-up.

Regular Cleaning Routines

Consistent cleaning routines are instrumental in diminishing static. Dust-free components, especially the printer head, are critical in preventing static interference with sublimation printing. Minimizing static and dust through regular cleaning helps avoid issues such as printer jams and clogged nozzles, as static attracts dust, which can exacerbate these problems.

The cleaning process should focus on the printer head and surrounding areas to ensure efficient prevention of static electricity. This includes using electrostatic brushes specifically designed for printers. These brushes can help solve static issues and should be included in the cleaning routine.

Checking for Wear and Tear

Conducting regular checks on your printer for indications of wear and tear is also imperative. Severe static electricity may damage the electronic components, such as the motherboard and print head of a sublimation printer, including causing harm to transistors and metal wiring.

Before touching the printer casing, you should discharge any static electricity from your body to prevent static damage. This can be done either by touching metal objects or washing hands. For those frequently working on printer maintenance, using an anti-static wrist strap is highly recommended.

Adjusting Printing Speed and Operation

Were you aware that the speed of your printing can elevate the likelihood of static electricity generation in sublimation printing equipment? That’s right: faster printing speeds can make static build-up more likely.

However, there’s a simple solution: adjusting the printing speed to a slower setting. By reducing the velocity of moving parts, you can potentially minimize static electricity generation, preventing static build-up and ensuring better print quality.


In conclusion, static electricity is a common issue in sublimation printing, but it can be effectively managed with the right strategies. Whether it’s grounding your printer, controlling the environment in your print shop, employing anti-static measures, or regular maintenance, there are numerous ways to prevent, control, and even eliminate static electricity. So don’t let static electricity get in the way of your printing. Take control, take action, and keep the sparks at bay!
