if you have a new developer for the machine great, if not empty the dev out so you can reuse it.
pull the mag roller and clean the crap out of it with a green scrub pad, then wipe it down with alcohol.
make sure the mag roller is clean and dry, then reassemble the unit and add the developer.
if its new dev then run your setup process, if not run your tests and make sure its adding the toner.
test the crap out of it. I have been able to get clients up and running using this method.

Shadow,
How did you figure that out? I suspected a flow problem
of some kind. So I took the top off hoping to find a clump
of toner. Everything looked normal. Hand turned it, nothing
came up. So I went for some developer. When I came
back, on the advice of Rrodgers, I swapped the cyan &
black drum. Ran 25 pages, looked good, 25 more, OK.
He ran 1000 pages and finished his job on time.
And all looked good.
I will check on this unit next week.
Both the drums looked in good shape and the life was
about 45% on all the drums.
Shadow,
I remember I used to clean the mag roller on some Kodak
machines like that because it improved the flow.
They would build up a brown film between the developer
and the roller. That would affect the brush on the mag
roller.
Well swapping the drums was a quicker fix for 5:30pm Friday.

Thanks Rrodgers and Shadow

It's back, this black band down a page that is mostly yellow.
I will see this tomorrow, Shadow, I may get a chance to use
your suggestion.
A fat spot on the upper center of the mag roller is what
I saw last time.

Yesterday, I cleaned up the transfer belt unit. The transfer rollers had a magenta tint. I dry cleaned them
the best I could, cleaned hard rubber with a water damp cloth, didn't help.
Today, Saturday, I cleaned out the black dv unit and cleaned the mag roller.
All seemed to go normally, except now it is stuck in please wait warming up.
I have been waiting at least an hour, recycled the pwr a couple of times, reset
the fuser section a couple of times. The fuser feels warm enough for 20lb paper.
What did I do? What am I missing??

Recycle the pwr again and recycle pwr on fiery at same time.

Thanks

did you remove the toner sensor from the dev unit before you cleaned it ?
double check the connectors and the grounds for the unit.
power off the fiery and the machine.
restart the machine only while holding down the utility/counter button and check settings in the service mode.
reset the appropriate counters.
its also possible that you have a bad printer control board as well.

Re: Ikon CPP550 (Pro BH 5500) Black band on 17" color prints from fiery but not copy

Shadow, Thanks for the reply.
Yes I did remove the toner sensor before vacuuming the
DV unit. I didn't use a scotch brite but I did have a fiber
filter that was not as abrasive. And cleaned it with alcohol.
Everthing seemed normal, I was able to enter service the
usual way and reset the black DV, I ran the toner sensor
program to set the mix level & auto gamma.
It let me select and run all programs until
I went to print out a test print for the printer gamma sensor
offset manual adjust and all it would say is warming up.
I checked all the settings I selected, OK.
I double checked the connectors and kept the door open
long enough so I knew it have to warm up. And I watched.
The lower fuser lamp was not coming on. It turns all four of
upper lamps on and off as it turns.
And it felt warm enough for the 20lb I had selected.
This was the last thing I found, I was out of time today.
Monday I will check the lamp for an open. I hope that's all
it is.

I've had problems with the video cable that connects the Fiery to the machine, it can cause a symptom like you have.
It would explain why the problem doesn't appear on copies. The black band usually covers most of the page in my case though.
It would be worth removing and refitting the cable.

Re: Ikon CPP550 (Pro BH 5500) Black band on 17" color prints from fiery but not copy

ineo+6501,
That actually makes sense given the symptoms.
It's quick and easy.
I will give this a try, but it does not explain why
there is a fat spot on the mag rlr or why I got this
on some copy with the fiery off. Unless it just takes
a few more copies to clear it up than I ran.
I will see this machine this morning.

Thanks

Re: Ikon CPP550 (Pro BH 5500) Black band on 17" color prints from fiery but not copy

Today I got a C3911 and a C3912 code. 3911 sez lower roller did not
heat up fast enough and the 3912 sez the belt did not get hot enough.

I have ohmed all thermistors, thermostats and lamps for the fuser section.
The upper lamps do come on and the rollers turn, but nothing from the
lower lamp.
I also checked the ACDB for signs of arcing and sparking (none found)
also reseated all connectors on the board and in the general area.
I also disconnected all option connected to the machine, no change.
Everything seemed normal 'cept for the lower lamp not heating up.
I have looked at the connector on the back of the fuser and in the
machine. They look normal.

I had just done a black dv change and this started.
Does the ACDB just fail like that?

Comments please

Re: Ikon CPP550 (Pro BH 5500) Black band on 17" color prints from fiery but not copy

Update:

The other day I did a visual check to see if the upper lamps were coming on and from what I could
see they were. But I could not see the ends of all the lamps, so I got thrown off track by an assumption.
Today I found one of the three upper lamps is open. I have not been able to see if there is a series
connection with these lamps. Does anyone know for sure?

Also I checked the line voltage and it reads 248.5VAC. I know this is over the 240VAC rating. Just thought
I would mention it in case someone knows if this is to much.

Thanks

Re: Ikon CPP550 (Pro BH 5500) Black band on 17" color prints from fiery but not copy

I replaced the upper fuser lamps and it warmed up normally and I was able to make copies. My customer ran a few things,
not enough to satisfy me but the print looked OK except for for some streaks. Some of which line up with wear I see
on the transfer belt. According to the machine the transfer belt has 552K on the part meter.
I recommended changing this before it went out to the customer, but sales said no, it is making a good copy now. And
sales also said these have been know to go past their rated page count. I told them I agree but this unit was sitting
for awhile and it can only go so far before it's worn out. This problem did not show up with the paper I was running
in the shop. Shop paper is always stored loose and unwrapped for the most part. I had some heavy paper, but not
as heavy as the customer is running.

How far past its rated mileage can the transfer belt reasonably go?

I see that the transfer belt part numbers from the C500 and C5500 are different.
Is it possible that I could put in an entire C500 transfer belt in the C5500 and
have it work?

Thanks

Re: Ikon CPP550 (Pro BH 5500) Black band on 17" color prints from fiery but not copy

I personally would tell the sales department to stuff it and go ahead and replace the transfer belt.
If they place that machine and the client does not like the copy / print due to the streaks, then you may not have the machine there for very long.

If the part numbers are different, then there is a difference in the parts. they may look identical from the outside, but there may be a change on the internal parts.
I just wish that Konica Minolta would standardize their parts system and have a good cross reference list of what works for each machine.
that would save so much on doubling up of parts. JMHO

Re: Ikon CPP550 (Pro BH 5500) Black band on 17" color prints from fiery but not copy

Shadow,

I made my case and they will spring for the belt. Customer will
buy the blade.
You are right about standardizing the part numbers, it would
make it easier for the dealer. But this is a revenue generating
gimmick. This way you keep 1 of a couple of different part
numbers, when you could get away with stocking 1 item
for three different models.$$
I think I will just have to get the two side by side and see for
myself. Now at least I will have a belt from the C5500/C6500
to try on the Pro C500.
I feel better now anyway.

Thanks

Hi Guys,
FYI the transfer belt is different between C500 and C6500. The belt on C6500 is thinner. I wouldn't try C500 transfer belt in C6500, you might get some interesting results
