C450 refreshing the transfer belt

Re: C450 refreshing the transfer belt

Being a technical person I am sure you will understand what I am & all others are trying to tell you.
HOPE THIS IS CLOSED NOW.

I am wondering if that is the case. We DO get a lot of end users on this site.

Re: C450 refreshing the transfer belt

Is this for real? This person actually thinks they are going to get help "demanding" we answer the question, on a 20 yr old machine! You wore my patience down! I tried to help.

Listen dude if you are that stupid not knowing that the "special tool / jig" mentioned in the service manual is a jumper for the interlock switch then you need to look into another profession (if you really are a tech). You can fold up a piece of paper and use it in place of that "special jig"!

NOW CASE CLOSED, short of asking admin to delete this thread!

Re: C450 refreshing the transfer belt

OK guy now you are becoming personal, ... fine. One of the classical persons not reading anything as it seems. If you would have ever carefully read my initial posting, you would have recognized, that I am referring to exact pages in the service manual. Your "help" was to post the page about belt refreshing that I was referring to, ...
Now you are calling me stupid, and do as if "old machines" are something bad. BTW the C450 was introduced by Konica Minolta in April 2005, not 20 years ago. It seems you are one of the technicians who preferre to talk customers into new leasing contracts than doing a good job. So please if you do not have to say anything stop talking and highjacking this thread with completely different statements than what I was asking.

For the rest of you, and I know this forum the last 2 years as very respectful and frindly, I still want to understand the procedure, and would like to understand the switch and "predrive". Of course the new belt is ordered already.

Re: C450 refreshing the transfer belt

Are you trolling us? You are obsessing over understanding the inner-workings of a process that is not even relevant to your situation. The question you are repeatedly asking is so base that it flies under the radar of most technicians: are you really asking how a microswitch/reed switch functions? I mean...it's a switch. Just press the damn button. The switch is almost always just a tiny strip of springy-metal that actuates a tiny button when pressed. That's it. 99% of techs have never laid hands on an "interlock jig", because all you have to do is cram a wad of paper in there. Or a screwdriver. Or a finger.

I honestly can't tell if you are trolling. If you are truly this intrigued by the nuances of your machine, you should read the Theory manual. It's...uh...a real thrill.

Re: C450 refreshing the transfer belt

To answer the question... open the left door and notice the actuator arm that is standing up on the door, this is what closes the safety switch when the door is closed. Press the safety switch with what ever fits in the small space so it closes the switch, predrive I believe is just the machine booting up after you close the safety switch ( it's called safety for a reason) once the machine stops running loosen the screw up that is pointed to in the manual, this will allow the belt refresh pad to be able to be used. The pad is spring loaded and will contact the belt, you can press the plastic housing on either side of the screw you loosened up in order to put more pressure on the pad for cleaning purposes. Press the start key and hold pressure on the pad until it stops. Remember to tighten the screw fully when finished since this retracks the cleaning pad, remove your safety switch cheater (wad of paper or what ever you used to actuate the safety switch) then close the left door and exit out of service mode.

THAT would be a GREAT IDEA!

And that is the main issue. Of coures I tried the switch several times (with screwdriver, some paper, and even a "self made jig" looking similar to those from the service manual made of hard rubber) and tried many things before I wrote my initial posting. But when I press the switch just backwards, what feels like if a button inside is pressed, nothing is happening at all. Thats why I asked how the switch should work, what may have sounded dumb, but I thought perhaps (as you have to turn the jig if you have one) there is some other button anywhere inside that gets pressed at turning the jig.
So the main issue is still that there is nothing happening if I press the switch. No "predrive" in any form, and the Start button stays orange an is not getting green, whatever I try.

loosen the screw up that is pointed to in the manual, this will allow the belt refresh pad to be able to be used.

Thanks for explaining the pad and the possibility for more pressure. I will give it another try tomorrow with both belts.
