This abnormal condition recurs even a specified period of time after FM18 is turned OFF and then turned ON, and an error detection signal (blowout of a fuse) is detected. At this time, an error detection signal (24V cut off) is not detected.

SC46-01* APC abnormality. While in the image write, APC is not applicable for the correction of the sub scan beam. Due to the 12V DC power for the laser drive not supplied, the MPC being wrong and the laser defective, the laser does not light up. Also, due to the rotation of the polygon mirror unavailable, the displacement of the index sensor, and the index sensor being defec-tive, the index sensor cannot detect the laser.

If there is a copy being made, the main body com-pletes the paper exit before stop-ping operations. Turn OFF the RL1 (main).

SC46-05* Compression input FIFO abnor-mality. An error interrupt occurs with the compression/expansion chip FIFO.

SC46-06* Elongation abnormality. Due to the elongation of data the compres-sion of which is not completed, the destruction of the compressed data and the abnormal length of data, an elongation abnormality is detected.

C. Function to detach defective sections

For those abnormalities listed in the table below, defective units can be detached temporarily to use other con-trol units.

While detached, an error detection is not carried out on these detached units.There are 2 methods of setting for limited use.

(1) User operation

When an error code occurs, press the HELP key following the message on the LCD and then turn the powerswitch (SW2) OFF and ON. This allows you to use it temporarily until the main power switch (SW1) is OFF andON (including an OFF/ON operation by the weekly timer) next time.

(2) DIPSW setting

Turning the main switch OFF and ON after setting the specified software DIPSW bit allows you to make a limiteduse of it until the bit setting is released next time (this requires the OFF/ON operation of the main power switch(SW1)).
