    • Is the charge corona different than the corona assembly I just installed? If so where is it located in relationship to the corona assemby?

    The charge corona looks clean, is there anything else that would put blank lines running verically down the copy?

You need to clean the charge corona.An eraser will work.I use a folded piece of scotch brite pad held with a pair of hemostats.Be careful not to break the wire.Good Luck!

    The charge corona assembly is on top of the drum, at about the 12 O'clock position or thereabouts.The one on the bottom is the transfer and separation corona.Both should be fairly simple to remove and replace.Good Luck.

Dark, streaked copies

I would first start by cleaning the optic's & cleaning the primary & transfer corona wires and do a general cleaning and that may solve your problem? Good Luck

Panasonic FP-7735 error E7-01

E701 is reported when the controller is unable to communicate with the IOT(image output terminal).The following check might save some further troubles.
1.If the the controller is pretag 2,connect a terminator to the SCSI port marked "HOST"
2.Disconnect the IOT,power up the controller,press the reset switch on the controller board and allow reset cycle to complete,power down,reconnect,insert floppy firmware,power up.
3.Down grade to firmware 2.7
4.Check PSU +5V and +12V at the pcb.
5.Check HD drive present on the config printout.
6.Check reset switch if not stuck in on controller.
7.Check controller to IOT cable in good condition.
8.Replaced the flash SIMMs
And lastly if all the above fail to cure the fault then replaced the controller board.

Panasonic FP-7735 trouble shooting

That could be a few things. Your corona wires might need replacing. Something with the middle transport section, where one of the corona assemblies is at, is not making contact properly. Or it could be the high voltage power supply.
