Recurring f2-40 on BP-70C55

[danny464]

Has anyone had a recurring f2-40 error code on a BP model? Specifically BP-70C55.

Error comes back maybe 2 times a month. Weird thing is we noticed the black toner is also getting ejected with 20-30% toner left inside.

We replaced the toner cartridge and that is it. It is a church doing booklets 8.5x11 and the first page is almost 100% coverage and Sharp said something about that could be causing issues but since it is 8.5x11 paper folded in half that is basically 50% coverage so no idea how that could be causing an issue.

I would check the toner hopper and replace it, if possible. This would happen a lot on CR4's on various colours. I hope this isn't going to be a common thing on the CR5's.

I've only seen this on 70 and 71 series, but only with non-genuine toner.

We only use OEM toners so it should not be an issue with toner.
We replaced the developer material and it has been running fine but lets see if it lasts. If not, we will try the tonner hopper. Thank you!
