Hi all, I have to do some laser printer electronic circuit troubleshooting for my father.
I have downloaded it's service manual already and I already fixed a issue with it's fixer unit.
[It's completely a replacement of a OP amp chip].
Now the problem is somekind of mechanical problem had arise.Believe me this is the first time that I'm
reading a mechanical part of a service manual like this.
I have refereed to the mechanical symbols already but it mentioned it as 'RETURN'.But what the heck
is 'Return' ? [In here : http://enginemechanics.tpub.com/14105/i ... _202_1.jpg ]. And it's something
related to hydraulics or some kind according to them. But the printer that I describe does not contain any
hydraulic system at all.
What's the meaning of that dashed wide line there? Connecting motor,photodrum, fixing unit , etcetc.
