After power on the machine, always there is following message on the display:
”FATAL ERROR 20”. If anyone had similar problem please help.I have not electric diagrams.
Hi,
There are two boards UCM and UCP.When appears message "Fetel error 20":
- failure in UCM
- failure in UCP
- connection problems between them
The connections are well.The count sensors are new.There are problems in UCM or UCP.
The UCM recives the control signals from UCP, provide power supply, control the electromechanical devices, the snsors and the optical encoder.
The UCP supervises and controls UCM, controls and comunicates with the scaner, stores and processes the data read, receives the operator's commands through the keyboard and display, controls the communication with the Host and the classification process of accepted and rejected documents.
I think that problem is in UCP board.I had replaced most elements without several chips (I can not find them) EF68B09P;EF6840P;EF68B50P. Probably EF68B09P - 8-bit microprocessor is damaged.I do not know.
There is not authorized service center nearby.
Ok then. Look for the problem into the Z80 board. FatErr20 means (as Multiscan told me once) "Z80 Board doesn't respond properly" usual reason is count sensors broken, dirty or miss adjusted but may be anything.
