The most straightforward reason is that the air tank is empty, and the apparent fix is to swap it out for a filled tank.

Check whether your gun is inside and out clean if that isn’t the issue. Some firearms may be practically problem-free for years, others may have daily issues.

Many issues with paintball weapons are relatively frequent and easily fixable. The following advice addresses the typical issues with conventional blowback-style paintball guns, including Spyders and Tippmann.

  • It would help if you first turned on your marker, then simply turning on your marker should ignite a fire with your rifle.
  • Your ASA may not be active, so activating it will address the problem.
  • Your battery may be flat or undercharged, so another possibility is that you are utilizing a defective product. Your shooting issue was solved by changing the battery.
  • You might have the DWELL value set too low, while if you tried raising it, that might be beneficial.
  • Your trigger setup is flawed; thus it’s ideal for tweaking, so the microswitch fully opens and closes.
  • The breach sensor has no paint, so you could accidentally turn it on. In this situation, the loader can fill with paint, and the feed tube and loader must check for obstructions.
  • The wire for the pilot valve hasn’t been plugged in with its PCB port.
  • Look for any damaged PCBs and swap them out for fresh ones.
  • Examine the pilot valve for damage, and a solution is to replace it.
  • A chronically depressed trigger may cause the marker not to shoot after you turn it on. The trigger should ideally adjust in this situation so that the chosen detection method is deactivated when it is released.

Tips and Advice For Maintaining Paintball Guns

Any player with access to a handbook, a functional tool, and basic paintball gun knowledge can rapidly fix most common paintball gun faults with classic blow-style alternatives like Tippmanns and Spyders.

However, some severe problems could necessitate a player to seek the advice of a professional. Therefore, the troubleshooting techniques listed below should be able to assist you in fixing any paintball problems you may be experiencing if your paintball gun won’t fire.

  • Make sure the barrels of your paintball gun are not blocked by anything.
  • Make sure your paintball gun’s O-rings are adequately greased.
  • Verify the security of each connection in your paintball gun.
  • Make sure the compressed air or CO2 tank is attached correctly and filled.
  • Please make sure the trigger component on your paintball pistol is not jammed or broken by checking it.
  • As directed by the manufacturer, properly clean the paintball gun.
  • Please make sure the paintballs are the appropriate size and unharmed by visually inspecting them.

Are Paintball Guns Needed For Oiling?

You should read the owner’s manual for your rifle before lubricating or greasing any marking components. These days, a lot of firearms are made to function without oil.

However, some oils can harm some of the components of paintball weapons. It is typically better to altogether avoid lubricating your marker.

Use only premium synthetic lubricants made especially for paintball guns if you need to lubricate your paintball gun. They are available from any paintball retailer.

Your marker’s metal components must be cleaned by rubbing oil on a clean cloth. Keep oil off of the plastic components because doing so could eventually cause them to degrade.
The pilot valve cable needs to be stopped into its PCB port, which you forgot to do.

Please make sure no dangerous PCBs are present, then replace them with fresh ones. Examine the pilot valve for damage, as it can be replaced with an answer.

If you have set the marker, it is still active and may very well point to a permanently disallowed trigger. Until it disables its preferred recognition approach when you discharge it, resetting the trigger is the best course of action in this scenario.

The rundown above demonstrates that many factors could result in a paintball weapon rather than a firearm. Another possibility is that the paintballs in the gun are not appropriately placed.

In that case, it suggests that you have a large barrel and a little paintball, indicating that your barrel is too large for the paintballs.

What Could I Do To Improve The Consistency Of My Marker’s Chronograph Readings?

A few factors strongly influence the speed and reliability of your marker’s chronograph. We’ll review a few that can enhance your marker’s chronograph performance.

Overall Consistency And Quality Of Paintballs

This is more a function of the paintballs you are firing than your marker. This may be the most critical element affecting chronograph consistency.

The size, weight, and form (roundness) of each paintball will significantly impact how it discharges from your marker. The superior your chronograph function should be, the more uniform each paintball should be in size, weight, and shape.

Size Of Paintballs To Barrel Bore Size

The relationship between paintball size and barrel bore size has long been controversial. This general principle is unquestionable. Let’s say the paintball is less tightly packed in the barrel hollow.

If the paintball is looser in the barrel bore, you will experience less velocity (More air pressure is lost by leaving all around the paintball before it exits the barrel than was needed to drive the paintball out of the barrel).

Your paint and marker will perform better overall due to other considerations, but for now, let’s focus on the chronograph performance. Here is a quick approach for comparing a bore size fit to a paint size match:

1. Take out the marker’s barrel.
2. Pour a paintball marker into the container (back).
3. At the start of the barrel, the paintball ought to suspend itself.
4. The paintball should be allowed to pass through the barrel without resistance if applied with any force.

Maintenance Of The Engine, Regulator, and Battery

Paintball markers move air through a succession of chambers and seals, pushing the paintball out of the barrel when it finally reaches there. Regular engine and regulator maintenance can help ensure reliable performance, aiding in reliable chronograph speeds.

Maintaining a high-efficiency level will require regular battery replacement and lubricating your marker according to the manufacturer’s recommended schedule. Test your marker every day before going to the chronograph station if it operates on dual pressure (with settings for LPR and HPR).


Even while most frequent paintball gun problems are simple to remedy, staying away from them is still preferable. Keeping your Paintball gun in good operating order ensures you’re always at the top of your game.

Maintaining your weapons makes sense rather than waiting until they malfunction on the field since, as we all know, prevention is always preferable to cure.

Ensure you clean or maintain your equipment per the owner’s manual’s directions. This requires that you follow the manual’s instructions and use the proper oil type.

Additionally, try not to disassemble your marker too often to prevent losing some bolts. Make sure to grease the sides and back 0-rings before each paintball game, so just be careful not to overdo it.
