Mf6590 tray wont stay latch - Canon imageCLASS MF6590 Copier

Could be a broken or defective retaining latch

Release the latch that holds the lever up.

That suggests either that the jam or clearing it physically damaged something, or that despite looking carefully there is still at least a little bit of paper jammed in there somewhere. I do't know how often my printers have jammed on something very much smaller than my little finger nail...

Hello,
as you probably know the problem is in crashed system software, which needs to be uploaded again.
I can help you with documentation and sst. write me on [email protected].

Hope that helps!

PS the new MF6590 is a little bit higher price then 200USD. In Europe like 500USD.

Check the fixing section sensor flappers. Thats my wild quess.

where exactly do you have paper jam

Open the left cover and inspect the paper tray and the fuser unit.90% paper jam in the fuser/exit unit.Inspect and clean the rollers and the fingers.
