SC390: TD sensor error

-Definition- [B]

The TD sensor outputs less than 0.5V or more than 4.0V 10 times consecutively

during copying.

- Possible causes -

· TD sensor abnormal
· Poor connection of the PCU

SC390 = Toner Density Sensor abormality

Possible causes:

• Poor concentration of developer
• Toner density sensor faulty

Are the prints/copies coming out ok? If the copies are very faint or heavily overtoned then changing the developer may cure the error code. If the copies look OK then you probably need to get the toner density sensor replaced by an engineer.

Hope this helps.

The TD sensor is reading an abnormal value, this could happen if no toner is getting into the developer unit or it could be a bad TD connection or TD failure. Would suggest checking to see if the toner supply path is working first.

Check that the toner bottle is empty and most of the toner in the development unit is depleted.Add a new bottle of toner, run a forced toner until it looks good, then run td initialization.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response

Thanks, Joe

SC390: TD sensor error

- Possible causes -

· TD sensor abnormal
· Poor connection of the PCU

SC390 TD sensor error The BICU detects the TD sensor outputting abnormal voltage (less than 0.2 V or more than 4.0 V) 10 times consecutively. • Defective TD sensor • Loose connection of the PCU
you may need a new PCU unit

SC322 Laser synchronization error SC324 LD drive current over SC390 TD sensor error 1 SC374 Development bias leak SC393 TD sensor error 2 SC401 Transfer roller leak error 1

Ask here, there are already many Hinari manuals.

the problem is with the toner density sensor.a quick fix would be to replace the photoconductor unit.thereafter you need to do the developer initialization adjustment.
