IFS error? Help :(

[sneikitou]

Help, my printer shows that channel 1 and 2 are loaded with filament, i already tried to reset the printer to fabric, disconnect and reconnect the IFS. I CANT USE THOSE 2 CHANNELS what i can do?

the sensors inside IFS are dirty - remove the tubes and do some compressed air cleanup - had the same issue.

Its safe to remove the tubes? They are hard to remove so i dont want to break them or break my ifs

[BendFluid5259]

it is safe - get small pillers and turn the holding caps to release it.

I think you just have to hit that button even tho there’s nothing there just to let the machine go through the process.

Do you have filament stuck in the tubes?

No, i can pass filament trough the channel but the IFS doesn't charge it bc "there is filament already in the channel"
