WHAT IS NORMAL DRV LOADER BEHAVIOR?

Under normal operation, the DRV Loader should:

• Power on quickly
• Feed paint consistently
• Respond smoothly to user input
• Operate with minimal delay

Minor variations in sound, feed rate, or motor feel are normal and may vary based on paint condition, battery level, and rate of fire.

WHAT IS NORMAL MOTOR BEHAVIOR?

Motor operation depends on your display version and the software installed on the Main PCB (Printed Circuit Board).

Smart Display (USB-C) — The motor operates using a continuous spin feeding profile and ships with the latest Main PCB software pre-installed.

Original Display (Micro USB) — The motor operates using a pulsed feeding profile during normal operation. If an Original Display loader has received the latest Main PCB software during a service event, the motor will also operate using the continuous spin feeding profile.

WHAT IS THE DIFFERENCE BETWEEN PULSED AND CONTINUOUS MOTOR OPERATION?

The primary difference is the timing of the automatic anti-jam feature.

• Continuous spin operation engages the anti-jam system slightly faster.
• Pulsed operation engages the anti-jam system slightly later.

Overall feeding performance remains comparable between both operating profiles.

WHEN SHOULD I TROUBLESHOOT?

Minor differences in motor sound, vibration, or feel are normal.

If you experience any of the following, refer to the Troubleshooting section:

• Inconsistent feeding
• Failure to power on
• Frequent jams
• Unexpected motor behavior
• Display or input issues

The DRV Loader charges through its USB-C charging port using a USB-C cable connected to a wall power source.

During charging, the charging indicator light will illuminate red. Once the battery reaches a full charge, the indicator light will turn off. This is normal and indicates that charging is complete.

The battery level displayed on the loader is shown in 25% increments (25%, 50%, 75%, and 100%). Depending on usage and battery condition, the displayed percentage may not change immediately during charging or operation.

A fully depleted battery typically requires approximately 2.5 to 3 hours to reach a full charge when connected to a standard wall outlet and appropriate USB power adapter.

To help prevent unintended battery drain, the DRV Loader also includes a configurable Auto Shutdown feature. This feature automatically powers the loader off after a period of inactivity, helping protect battery life if the loader is accidentally left on or activated while stored in a gear bag.

Auto Shutdown settings can be adjusted by navigating the loader's menu to Shutdown on your DRV display.

If your loader is not charging, the charging indicator behaves differently than described above, or battery life appears unusually short, refer to the Troubleshooting section for additional guidance.

For optimal performance and battery longevity, recharge your DRV Loader when the battery voltage approaches 3.6V.

Battery percentage is displayed in 25% increments and may not always accurately reflect the remaining charge. For the most reliable indication of battery status, monitor the battery voltage shown in the loader's display menu.

As a general guideline:

• Above 3.6V – Battery charge is typically sufficient for continued use.
• Around 3.6V – Recommended time to recharge.
• Below 3.6V – Recharge the battery as soon as practical to ensure consistent loader performance.

The example below shows the location of the battery voltage reading on the loader display. The voltage value is highlighted with an orange circle.

DRV SOFTWARE ARCHITECTURE

If you continue to notice unusual battery behavior beyond inaccurate percentage readings, contact CRBN Support for assistance.

If your DRV Loader is not feeding consistently, follow the troubleshooting steps below to identify and resolve the issue.

1. AVOID OVERPACKING THE LOADER

For best feeding performance, turn the loader on before loading paint. This allows the loader to pre-load the ball stack and raceway before use.

• Power on the loader first
• Load paintballs into the hopper
• Allow the loader to pre-load the stack automatically
• Avoid forcing additional paint into the shell or overfilling the loader

Overpacking the loader can restrict paint movement and negatively affect feeding performance.

2. VERIFY THE DRIVE SYSTEM IS INSTALLED CORRECTLY

Inspect the drive assembly and confirm all components are properly installed and seated.

• Verify that the two halves of the main body (tray) are properly aligned, fully seated, and securely fastened.
• Ensure the drive paddle and assembly are correctly positioned
• Check for any loose or improperly installed components

REFERENCE EXAMPLE

The images below illustrate the correct and incorrect alignment of the two halves of the main body (tray). Use these examples to verify that the tray is properly assembled and securely fastened. The incorrect examples highlight a common assembly error where the tab on the bottom half of the tray is not fully seated in the corresponding slot on the top half. Below the images is a quick guide video showing how to correctly assemble the two halves of the main body (tray).

CORRECT

INCORRECT

3. CHECK YOUR PAINT

Empty all paint from the loader and inspect the paintballs being used plus the drive paddle and raceway for obstructions.

• Verify the paint is not swollen, dimpled, or out of round
• Remove any broken paint from the loader
• Thoroughly clean the interior if paint or debris is present
• Test with a fresh, high-quality batch of paint if possible

4. INCREASE THE FORCE SETTING

If feeding issues persist, increase the loader's Force setting to 4 or 5 and retest.

You can adjust the loader's Force setting by navigating the loader's menu to Force on your DRV display.

5. CHECK CLUTCH SPRING TENSION

Incorrect clutch spring tension can affect feeding consistency and overall loader performance. Use the following test to verify that the clutch spring is operating within the correct range.

HOW TO CHECK SPRING TENSION

1. Ensure the loader is powered on.
2. Confirm the loader's Force setting is set to 3 by navigating the loader's menu to Force on your DRV display.
3. Insert a finger into the feed tube from the bottom of the main body (tray) to block the anti-jam eyes.
4. Using a finger from the top of the main body (tray), prevent the drive paddle from rotating.
5. While holding the paddle stationary, observe the position of the clutch spring tab end.
6. Compare the spring tab end position to the reference image below.

The position of the spring tab end indicates whether the loader has the proper clutch spring tension.

REFERENCE EXAMPLE

The image below shows a top-down view of the clutch spring during this test. The highlighted zone indicates the correct range for the spring tab end position. In the example shown, the spring tab end is located within the orange circle and the loader is set to the default Force setting of 3.

If the spring tab end does not fall within the highlighted range, reset the angle sensor and repeat the test. A quick guide video below the reference image demonstrates the angle sensor reset procedure.

IMPORTANT NOTE

Always keep the original top and bottom main body (tray) halves together. Each DRV loader is factory programmed and calibrated as a matched assembly. Interchanging main body (tray) halves between loaders can cause angle sensor misalignment and prevent proper operation.

STILL HAVING ISSUES

If the loader continues to feed inconsistently after completing the steps above, contact CRBN Support at support@crbnpaintball.com and include photos or video of the issue to assist with further diagnosis. Providing clear images or a short video of the loader's behavior can help expedite troubleshooting and resolution.

If your DRV display is not functioning properly, use the steps below to help identify the issue.

1. LOADER BEEN EXPOSED TO WATER

If your loader has been exposed to water, follow the steps below to properly clean, dry, and inspect it before returning it to use.

1. Power off the loader immediately. Do not turn it back on until all components have been thoroughly dried and reassembled.
2. Disassemble the loader, separating the shell, drive paddle, and both halves of the main body (tray).
3. Allow all components to air dry completely. Ensure that no moisture remains inside the tray, around the electronics, or within any connectors before reassembly.
4. Reassemble the loader and verify that all components are correctly installed and securely fastened.
5. Power on the loader and confirm that it is operating normally.

IMPORTANT

If the loader or display is not functioning correctly after exposure to water, allow additional time for all components to dry completely before submitting a warranty claim or service request. Residual moisture can temporarily affect operation and may resolve once the loader has fully dried.

2. VERIFY YOUR SOFTWARE VERSION

Ensure your loader is running the latest available Display PCB software version. Software updates can resolve certain display-related issues and improve overall system performance.

3. DOCUMENT THE ISSUE

Before contacting support, gather as much information as possible about the problem.

Depending on the cause of the issue, CRBN Support can assist with additional troubleshooting, repair, or replacement options.

The anti-jam system is designed to detect a stalled drive paddle and automatically reverse and continue feeding. Use the following test to verify that the system is functioning correctly.

HOW TO TEST THE ANTI-JAM SYSTEM

1. Ensure the loader is powered on.
2. From the top of the main body (tray), use a finger to prevent the drive paddle from rotating.
3. Observe the loader's response.

EXPECTED RESULT

When the drive paddle is blocked, the loader should produce an audible click and continue attempting to rotate the paddle. This indicates that the anti-jam system has detected the obstruction and is operating correctly.

IF THE ANTI-JAM SYSTEM DOES NOT ACTIVATE

If the loader does not click or continue attempting to rotate the paddle, the anti-jam system may not be functioning properly. Common causes include:

• Low battery charge.
• Dirty, obstructed, or malfunctioning anti-jam eyes.
• Incorrect assembly of the two halves of the main body (tray), which can misalign the drive gears or interfere with the anti-jam eyes. See the images below illustrating the correct and incorrect alignment of the two halves of the main body (tray). Use these examples to verify that the tray is properly assembled and securely fastened. The incorrect examples highlight a common assembly error where the tab on the bottom half of the tray is not fully seated in the corresponding slot on the top half.
