[Dead] BH 160 - does not boot

[LIOEEK]

Help anyone

well there's a jam in this bh 160 machine on the fusing unit but it's so hard to get so i dissamble the unit.. After removing the jam, and assembling it again.. i tried to switch it on but to my surprise the machine didn't boot.. you can only see black graphics on half of the screen.. there is no warming up just the fan motor is working.. i don't know where to start looking for the trouble..i'll just suppose to remove the jammed paper now the machine is not operational

thanks in advance for your help

Go back over your work. I would bet that there is either a connector not plugged in or a pinched wire somewhere.

As King said. This is untypical for the machine so indeed first thing coming to mind when having such a weird display is a pinched wire. Second a loose connector or a ribbon cable not sitting well.

What did you remove for removal of the fuser? Normally its only the four screws around the fuser frame and than the back cover to remove the power connector and the sensor connectors nothing else is necessary.

Actually, the main board and the HV board both have to be removed to get at the fuser.

Re: BH 160 - does not boot

Thanks for the suggestions king and hans. . I removed the back cover and slightly bend the mainboard on the side without removing the ribbons and wires. Wish me luck. hope I can make it work tomorrow, a simple jam turns to a big disaster )

Re: BH 160 - does not boot

I stand corrected. My mistake, I had the BH-162 in mind cause I was working in my workshop on several of them these days. Sorry 'bout that.....

In this case it is only the ribbon cables at the left which are not sitting well for 100% sure. Very common with this machine.
