TASKalfa 306ci F000 error

[Kriess]

Hello!
I would like to ask for help.
The printer throws the error code F000 after welcome screen.
I unplugged and plugged all the wires back in but the error persists.
I noticed that the memory slot is empty, is this normal?
What else do you suggest?

no communication between main pwb <--> operation panel pwb
From service manual/ phtograh main pwb, no memory installed on main pwb 30ppm system..
First easy solution:
If i remember correctly, on operation panel there you`ll find small emergency switch.
Change from [N] to [E] and restart the system.
System will run internal backup FW upgrade for operation panel without connected usb key.
Shut down the system
Change back to [N] position
Next start you has to run FW upgrade with complete firmware USB key.
Remove ES_Skip.ON file before running from the upgrade and system will write new communication data >> finished if usb port not blocked
This switch meanwhile would removed on newer systems

2nd solution
Exchange from pwbs needed

But i don`t think so...
