1, press "program", "interupt" "clear", "interupt"
2, enter 30, press "start", enter 01, pres start again,then all the sensor light in the paper path are on the abnormal one blinking.
3, repeat same step for 30 sub 02 that's for paper path in the feed section.
4, repeat same step for simulation 40 sub code 01,that's for by-pass paper path sensor.
After you done those procedure you will find out which sensor block out or defect, good luck.

SOURCE: AR-M257 service code L1-00

L1-00 is determined as "scanner feed trouble". The scanner unit (which holds the mirrors) is not moving as it should be. There are a few possibilities. Firstly, does the mirror unit move when the copier is turned on? if not it could be a disconnected/broken scanner wire or bad drive motor or simply dirt/debris or a loose wire binding the unit up.
If the unit moves on power up then it could be a bad sensor or a bad board not registering the signal from the sensor.
You can check the operation of these items in SIM mode : press the following keys one after the other "P" "*" "C" "*" then press 1 and enter/copy button and you'll see the option available.
I hope that helps.
