I have a Ricoh aficio 2018D problem is SC390 Code i reples PCU Unit Lower unit/Drum & Developer but sc390 code problem not solw. Please help Me.

Question edited tor a lot more clarity and add MAKER, but NO MODEL NUMBER! All questions need full make and model.

Replace developer, clean ID sensor

I've never seen a message like that with the 0390H code. There is no mention of that code in either the user manual or service manual. The closest thing is the sc390 code, which means either the toner density sensor or the developer has gone bad, and typically replacing the PCU can fix that problem.

If the new PCU doesn't fix the problem, you might want to try calling Ricoh for support, since their documentation doesn't mention that code.

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.

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

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.

Open the front and right covers and remove the toner bottle holder unit.
Pull out the Photoconductor unit(PCU) with your thumb pressing on the latch on the left side of the PCU.
Separate the top part from(drum) the bottom part(developer unit), by removing the front piece 1 screw and rear piece 2 screws and 1 coupling(pull out).
Now remove 1 front screw, 2 rear screws and other 2 top rear screws to separate the top and bottom parts of the dev. unit.
Then place your finger under the front-side and rear-side flaps and push out so that the flaps pops off the peg.
Set the coupling removed, back to the shaft and turn the coupling to remove the developer from the roller.
Turn upside down the lower part of the dev. unit to remove all the developer by turning its gears.
Load new developer evenly in the openings of the lower dev. unit and pay attention not to spill developer on the gears.
Reassemble the whole PCU properly.
Reinstall back the PCU and toner unit and close the front and right covers.
Switch on the machine, enter SP mode- Clear key, 107, hold and press Stop key.
Enter SP 2-214 and execute to reinitialize the TD sensor.
Switch off and on the machine.

Good luck and please rate me, thanks.
