010-398 on DCIV5070

[Popolopo]

At first left cover sign on even though it already close, open and close it doesn't help (077-301). Few minutes later, 010-398 appear.
Already change the interlock switch for left cover, the wiring for that switch, MCU, fusing unit fan, remove duplex unit. But the problem still haven't resolve.

Any suggestion to fix this?

Re: 010-398 on DCIV5070

I've encountered this. But no solution so far.

What I've done:
1. Swap and replace left interlock switch.
2. Swap left cover
3. Swap ESS
4. Swap MCU
5. Swap Fuser
6. Replace Exit sensor

I will try replacing the EXIT PWB. The square PWB on the right to toner hopper

but your error 010-398
is fuser exhaust fan failure... try to replace the fuser exhaust fan, its the nidec brand fan located on the rear side of machine

Already tried step 1,3,4. Will try the rest.
Also already replace the fuser fan, but the error keeps appearing.

Thanks

today's work:
7. Swap Exit PWB.
8. I traced the left cover switch cable (orange), everything is intact. Tested both side with multimeter, connectivity is fine.
9. I traced the exit sensor cable, everything is intact. Tested both side with multimeter, connectivity is fine.

Error 077-301 / close cover A still happens

010-398
its your duplex fan

number 23

PS PWB
check your 24v at j438/1 ( no 24V - Power save PWB)

Number: 2

Re: 010-398 on DCIV5070

Solved by changing EXIT PWB and Power Save PWB.

That is after changing fusing fan, MCU PWB and disconnect duplex.

thank you very much.
I can confirm that replacing Power Save PWB is the solution.
