If you're an ooze pen user, you might have encountered a common problem of your ooze pen blinking red four times. This can be frustrating, especially if you're trying to take a hit and the device won't work. Fortunately, there's a simple solution to this problem.
First, try putting the cart on the ooze pen, but not as tight as before. Loosen it a little and see if that solves the issue. Sometimes, the ooze pen's connection to the cart might be too tight, which can prevent it from functioning properly. By loosening the cart a bit, you allow for better airflow and connection between the cart and the ooze pen.
If that doesn't work, you can also try cleaning the contacts on the ooze pen and the cart. Sometimes, dirt and debris can accumulate on the contacts, which can disrupt the flow of electricity and prevent the device from working correctly.
In conclusion, if your ooze pen is blinking red four times, don't panic. Simply try loosening the cart and cleaning the contacts. If the problem persists, you may need to replace the cart or contact the manufacturer for further assistance.
