Panasonic FP 7718 error e3 40

E3-40 means there is a problem with the machine reading the black level density...this is not normally due to a faulty component but is normally due to to dirt inside the machine and possibly old/worn developer and /or drum in the machine. These are items that would have to be replaced by a service man.

The machine does not make copies showing an error E3 which i can not see where i can find it

e3 means a machine error and it need a service technician to fix it.
furthermore may i ask what e3 code displays on the screen (you might see something like this e3 10 , e3 40 , e3 01 etc)
i can still help you if it is e3 10

E3-50 is the malfunction of the transfer wire cleaner. The transfer wire assembly is under the drum. The transfer wire is on the right. The cleaner moves back and forth. If you feel comfortable taking it out, respond. There are fine metallic wires in each slot, so don't break them

Panasonic FP 7742 Copier

check drum and drum sensor. if the Drum cleaning blade (DCB) has failed and is smearing toner around the drum then the drum sensor can't see the drum. clean it with a brush. the sensor sits in the drum/ cleaning station.

Pitney Bowes Copier - C180 - Error E3

Sorry it took so long. Your copier probably is similar to a Toshiba E series. The error code is paper jammed in the bypass section.

Use this link as a lookup to the error codes

Use 4501 under Toshiba to find the error codes.

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.
