and if the reflecting mirror is stained.
2. Check if the harness between the aligning sensor and the RADF PC board is open-circuited.
3. Check if any conductor pattern on the RADF PC board is open- or short-circuited mainly
around IC1, IC14 and CN14.
4. Replace the aligning sensor.
5. Replace the RADF PC board.
6. Initialize the RADF's EEPROM and perform the sensor automatic adjustment.

thank you mr Spock . but i still junior , i try to solve by these steps.. no change ..is there mor solutions ..can you send me book of 311c please ...tahnk you very very very much

[Mr Spock]

Did you replace the adf pwb then initialize the eprom? If so then check the harness from the adf to the scanner (slg) pwb in the optics area.

on the early toshiba's a c7 error was a fuser error. You might try there.

[Mr Spock]

The 310c and the fc-22 book has the same error codes as the 311c book. Are you sure that is the only 2 digits of the code or that 310c is the fight model?

[ss12]

just checked the 310c handbook,c7 is afuser related error.check the usual suspects,thermistors therrmofuse& lamps before 08-700 fuser reset

[m_shamah]

yes Mr spok . it is too digit... c7>>>>>i will try to reset 08-700 and seee..
but i did not have handbook if any 1 had .310 or fc22.. or 311c...please share

[C7] Error C7
*To avoid any hazards, be sure to unplug the power cord before proceeding to check the items
in 1. and 2. below.
* Be sure that the fuser unit is set in place securely.
1. Check if any thermistor connector is disconnected.
2. Check if any harness of the thermistors (center/rear, upper/lower) is open-circuited.
3. Check the LGC board if the connector J122 is disconnected.
4. After completing the repair of what caused the [C7] problem, proceed to rewrite the status
counter (08-700) to "0", following the same procedure as for [C41] to [C48] .

This is from C310 HB

[Mr Spock]

I rechecked and that is in the book but not in the list of error codes at the front. And is as Ivovb has posted.

I think you will find C7 is a fuser lock out code 08-400 set to 0 clears code
