I just have to ask, is the LD 5100 the same as the BH Pro C500? We got
one in the shop, just the printer no doc feeder, and I want to make it run.
Right now it comes up with an SC 45-20 code. I know I just turned it on
for the first time and it could be a lot of things. My interest is I need the
fuser section.
How many of the parts are interchangeable?

Thanks

ld5100 is same with c500 and 8050.

45-20 is related with color registration.

pull out the transfer belt assy and look inside on left side there is 3 sensors behind 3auto shutters. is in a steel plate.
do not touch them with hand. use a blower brush and remove any dust from there.

also check transfer belt's position, see if it has jump over the bottom roller.

Thank you for the response, I kinda thought that was the case. One of
the people here at the shop seems to think it is different because he got
the code.
But hearing this is good for me, a customer just called on a machine he
bought from us a couple of weeks ago. A printer that thought he
could clean the transfer belt with rubbing alcohol.
I told him only 99% alcohol can be used, rubbing alcohol has mineral oil in
it and causes problems.
He said he was running something with a lot of black and now has a black
image on the transfer belt. Can this be cleaned with a soft cloth?
I would only use alcohol as a last ditch effort and then in a very limited
way.
What would cause the sticking of an image to the transfer? It must not
have discharged after the image was created and transfered. He said
his copies were ok untill he started getting ghost images. So he took
the transfer assy from a different unit he got from Ebay and is finishing
his job. I will see this unit tomorrow.
Also is it possible to get just the fuser web without buying the whole
assembly?


Thanks for any help

first remove the cleaning unit before cleaning otherwise this will effect the result , make sure that it is alcohol and not some oile in it.

:rolleyes:,
That printer just called back and cancelled. He had some other cleaner
that he used for the press to clean the blanket, not blanket wash,
I asked. He said it cleaned up no problem. Then he said before he started
he had cleaned the feed rollers with this rubber rejuvinator and then
started the job. He guessing that some of it tracked to the belt. I can
see I will have to give him some pointers on the basic stuff.
I would prefer not to show him, but he'll shoot himself in the foot if I
don't. Plus, he's also looking for a B/W copier.
I will get the name of that stuff and post it.

Thanks for the help

I prefer to use methanol. It does the job quite nicely in many cases for dealing with the transfer belt, for things such as label glue. It has a water like consistency to it though, so make sure any excess toner is cleaned off or it will smudge the toner and make cleanup of said toner that much more difficult. Generally however, a dry cloth is sufficient. The belt MUST be powdered after cleaning with any liquid regardless of type, though anything with oils in it should never be used.

I would agree 100% with your recommendation. But isn't it odd that the
customer could do that, without powdering and not have trouble?
I told him that the oil in rubbing alcohol will break down the cleaning blade
rubber and and damage the belt.

I suppose so it is a bit odd. He got lucky? Or he had foresight enough to powder with some toner? Or maybe he left the cleaning unit off when he went after that belt?

But perhaps he might not have problems now, but wait a while...sometimes these things take a bit...bit like battery acid on cloth...doesn't affect it right now, but wait until tomorrow. ;)

Yeah, that what I kinda thought. Sooner than later the belt will fail and
I'll be waiting.
