Sharp MX-M283N U2-90 Codes

[shoule]

Have a MX-M283N with U2-90 Code. Replaced PCU and PCU flashrom still cannot get the code to clear. When we reset the code the copier will start up and go in to CQ adjustment before the code comes back. The copier has around 60k on it.
Any suggestion

You probably have a bad EEPROM, not a flash rom. Save any data and counters that you can and replace EEPROM.
