Ricoh CL7000 Error SC 388

[tervel12]

Hello,

I am not very familiar with Ricoh machines so I am at a loss for troubleshooting this problem. I have cleaned the developer units and the transfer belt. The cyan unit looks to be in good shape and appears to be toned properly.

I am able to get into service mode and the internal prints look good. There is cyan where there should be cyan and it appears to be the correct density.

I checked the Vk levels for the colors and Y, M, and K and they are around +35. The cyan Vk value is -2950. Seems to be a bit off.

Is this a bad developer unit or ID sensor? Any help is appreciated.

Thank you!

Any of the following conditions happens three consecutive times:

•

When the development gamma is out of the following range: 0.3 ≤ γ ≥ 6.0

•

When Vk is out of the following range:-150V ≤ Vk ≥ 150V

•

Development gamma calculation error

•

Unsuitable toner density

•

Toner supply mechanism problem

Image transfer problem

1. Turn the main switch off and on .
2. Check the process control self-check
result (SP3-975). If the result is not .1., fix the problem according to the table in section 4.1.2.
3. Print a full color image by disabling SC detection (SP5-809-001) and check if the image quality is OK. If the image quality is not OK, fix the problem. Then, enable the SC detection again.

Check the process control read out. If it is an ID sensor issue, then instead of 1111, you get a 2 in the mix, then that is an ID sensor or transfer belt issue. A 6 is a Vk error.
6) Vk error.

1. ID sensor pattern density is too high or low.
2. Residual image on transfer belt
3. Toner dropped from development unit
4. Scratched or damaged transfer belt

1. Check the image development process and correct toner density if necessary.
2. Check the transfer belt cleaning unit.
3. Clean the development unit and correct toner density.
4. Replace the transfer belt.

It might be you need to replace the Cyan DV unit.

Thank you for the quick response.

I have ordered the color developer kit and will replace the developer unit. I will let you know if that takes care of it.

Thanks again,
