Fuji FP 232B error codes

[fujifreak]

Hello, I own a Fuji FP 232B mini lab and have been operating it for close to 2 decades now. Recently though, it is giving the error code 905 and I cannot get into the setting temperature limits and fix it. Can anyone help? thanks so much.

E905 means Control Data Abnormal. Reset Data.
Check film processor settings - Replenishment Rate, Pump Output, Temperatures Displayed, Evaporation Rate, Water Replenishment Rate and IX240 replenishment Factor. Some of them are out of limits.

To access standard menu ( from 0 to 3 ) press MODE. select menu number. Then enter sub-menu number .
To access supervisor menu ( from 4 to 6 ) press MODE. After that press MODE and menu number ( 4, 5, or 6 - two buttons at the same time ) . Then enter sub-menu.
To access maintenance menu ( from 7 to 9 ) press MODE. Then press MODE and YES ( two buttons at the same time ) . After that press MODE and menu number ( 7, 8, or 9 - two buttons at the same time ) . Then enter sub-menu.
Temperature set is menu 5, sub 1.
Temperature calibration - menu 7, sub 1.
Temperature correction - menu 7. sub 2
Might be out of limits is displayed temperature. Look what you see on input check ( menu 7, sub 3 ) . There can see temperatures from sensors.
