I have error code on Ricoh 2400 wide format, error say SC401-00. How I can resolve that problem

Ususally the Toner ID Sensor

But the Code is for these problems:

Clean the ID sensor.

• Check the ID sensor harness and

connector.

• Replace the ID sensor.

• Replace the MCU.

• Replace the development unit.
• Replace the CGB power pack.

You can cheat the ID Sensor but you will have to replace it soon.

If the ID sensor is damaged and cannot be replaced immediately, set SP2208

003 (Toner Supply Setting . Toner Supply Mode) to .1.. Then the customer can

continue to use the machine until a new ID sensor is available. After you install a
new ID sensor, reset this SP to 0.

To go into and use the SP mode

1. Push Yellow Clear Modes

2. Push copy quantity numbers 1,0,then 7

3. Push and hold Clear Stop for 3 seconds.

4. Input the group number (.1. for .Copier.). Then input the full SP number to go

directly to the SP code screen.

5. touch screen for SP direct then just tyoe the numbers in order do not put hyphen

6. Set the adjustment value.

7. Press the # key to set.

To go out of SP mode

1. Push the key on the operation panel below .Exit. one time or more, until you

are back at the initial copy screen.

2. Switch the main power switch off, then switch it on again.
NOTE: You must do this to enable the SP values that you input.
