4/4e series paper size on tray

[jwai]

Hello,

I found the bizhub 4/4e series have common issue below:
The tray 1 often have auto paper size detection error, place A4-> display 8 1/2" x 11" , place A3 -> display 11" x 17".
I tried to test the paper size detection sensors by exchanging them with tray 2 however the same result occurred.
Have any idea about this?

This is a know issue, the wire on the connector breaks, you need to replace the small loom.

Could it also be the marketing area is not set correctly?

They are " others 2 " on marketing area.
I found it is only happened on tray 1, tray 2 never.

Yes.

Yes.

Thank you,
can't imagine these wires would be broken without impact.

or somebody not pulling the connector properly .. never remove a connector by grabbing just the wire harness

I checked the connectors and 2 wires loosened,
it seems nothing happened on 8 series.

Probably because most users use tray 1 more often.
I have only 1 case and it happened because user do very much id card copy but they copy one side then put back paper to tray 1 and copy 2nd id card side
Too much open-close tray will over time damage this wires.
