If you were to change the pickup funnel so it's not centered, you could hit 2 discs simultaneously and not worry about the first one clearing before the 2nd disc comes in and jams the whole thing. You may also be able to increase the belt speed on that side slightly such that the offset side rollers pull disc #1 in faster, making it clear the intake before the 2nd disc's apex gets in front of it. It's pretty easy to increase the belt linear speed by increasing its drive roller slightly.
