Error "toner not recognized...." Toshiba e-studio 456

[gideon]

Still have the error "toner not recognized...". I changed the logic board still error, check the firmware setting it is US (NAD).
The 2 cartridges I tried are US OEM cartridges.
Firmware is up to date.
The only other option is the interface board or harness.

Anybody ever had the need to replace those?
Thanks

1. Make sure the front cover can be closed properly & firmly
2. Make sure genuine Toshiba toner is inserted
3. If not toner problem, try clean/replce the toner CTIF sensor *Inside the machine with 6 springs that touching the toner cartridge chip

Never had such issues on these range, I believe that it's worth to check CTIF Board and springs for any problems also if you have some washers that fit under the CTIF holder to get it a bit closer against the toner cartridge chip may have a positive result. Is the toner driver working if you had the chance to test it in Test Mode?
