Caution regarding running machine with ADU door open.DESCRIPTION: SOLUTION ID:
84071
SOLUTION:
Making copies while bypassing the door interlocks will result in high voltage output from the output
connector of the transfer/separation corona at the right front side. The machine should never be
run with the ADU door open.
Furthermore, for conventional models, paper feed was checked by keeping the front door open and
pressing the door interlock with a jig. However, for this model, even with the ADU door open, paper
feed cannot be seen since the guide plate covers the drum surface. For this reason, and the above
mentioned safety concerns, a door interlock jig is not provided for this model.
Note: See [[Safety Bulletin #58| IMAGE V:\bitmaps\cjc238.bmp SCROLL]] for more information.
