OC cover float detection 
level (OC FLOAT LEVEL)

[Function]
When this test command is executed, the current set value is displayed. When [OK/START] key is
pressed, the mirror base unit moves to the SPF scan position to acquire the OC cover float detection
level.

When the mirror base unit returns to the home position, the acquired value is displayed.

If the detection level is not acquired, ERR display is made. (Default: 0)

Note that, this test command must be executed with the OC cover closed.

∗

If the value is 0, float detection is not performed in normal jobs.

[Function]
For 20th sheet or later in multi copy, the fusing temperature is automatically changed from the temper-
ature set with test command 43-1 to the temperature set with this test command. 

When this test command is executed, the current set code number is displayed. Enter the code num-
ber and press [OK/START] key to change the setting.
