I've got a Konica 7020 and when attempting to make a copy it has a f-28-3 error.
I've found a couple of posts about how to fix this issue, but I do not find them particularly clear.
If anyone is able to give me some advice about a potential solution it would be much appreciated.

My machine has done about 40 000 copies.

Thank you.
