Ricoh 2020: sc 120

[White_Toner]

Dear sirs!
This machine makes copies without problems from ADF and exposure glass. But the interesting thing start when user try to scan. From ADF - no problem. When original is on the exposure glass, scanner starts move to the right, then to the left, through homeposition sensor, strikes of the copier body and error appears sc 120. No ideas in my minde

Clean the sensor and flag. Clean and lube the scanner rails should fix it.

thanks Venom! But i couldn't understand why in copier mode it works, but as scanner doesn't work. At the same time successfuly scan from ADF. On monday i'll try do clean sensor.
