IPF 9100 Multisensor error

Re: IPF 9100 Multisensor error

in service mode, machine fully started up but can`t print and not detect multisensor or cover door or paper for nozzle check!
i found a dead fuse in carriage Bord. (FU101).
i think this pass 3.3 volt for multisensor, but why that burned ?
any way, i replace this fuse and say that what will be happen .[ATTACH=CONFIG]30809[/ATTACH]

There are may reasons why a fuse blows & many types of them protect various operations
Without a component circuit diagram ( which Canon does not provide anymore ) u are frozen in time/

yes u can replace same type component> but will not be able to find the cause of action on fuse
also that fuse could be in line with other item

I would say in 90% of cases it is the heads.

You need to replace both print heads... and than continue with troubleshooting

Probably you did this, but:

Did you turn it on in Service Mode / try to print a nozzle

or while the printer off /remove both heads / turn on is service mode and see what happens

Can't tell you where to look exactly, because I don't know, but there are a lot of fuses that you have to check. For some of them if reading is 5 Ω or more, main controller PCB needsto be replaced.

Anyway I would just go get a new board...

Even if you knew which "part" is responsible - I don't think you would be able to fix it.

On some rare occasions we have been able to remove some transistors from one (broken) mainboard to another one.

But having only one board - where do you get the switching parts ?

at my city some electrical shop have some component apart of this i have 2 old head and carriage PCB.
I checked many not all switching transistor that was fine.
can any resistor cause malfunctioning or just check transistor ?

I have canon ipf 9100.
when turned on after some start up check ( not all ) on LCD appear multi sensor error and shut it down.
i know multi sensor is fine and my main PCB have problem.
any body can help me winch part of main PCB must replace to fix it.
thanks all.
