[Misc] CLC 1130 bad copies and printings

[mbgemini]

Hi to all. I've got a new problem with my CLC 1130. Some days ago it started printing like this picture
print020001.JPG

I made some cleanings, first of all of mirrors, I never made since I bought this machine used in winter 2011.
I cleaned the photosensitive drum cleaner assembly (cause I had also some problems with error codes --> Display\Dens\ Window-CMYK value 53) and changed its end felts
I changed the blades on the black toner concentration sensor ass.y
I made Auto Gradation Test and the result is like this (2nd test)

and this is a copy of a test sheet from the copyboard glass

Where starting to solve the problem?

Hi,

If i remember well, the drum and the starters are given for 40k prints. First, i would replace the starters. Verify the fixing upper roller and the transfer belt.

I know duration life for developers but for drums someone, in a previous post, told me that they can work until 100k.
Here are some data from service mode: TTL +/- 61400
TTL-color +/- 49500 (40700 COPY + 20700 PRNT)
TTL-K +/- 11900
and others in following pictures

But I noted now a strange thing: in another post (12-12-2011) I reported TTL 313K for this copier; but now it shows only TTL 61400 ??!!?? How is it possible? Can this value be changed if I change something on the copier (like i.e. photosensitive drum)??

However, in the meanwhile, I've made some PGTEST (04 - 05 - 10 - 14) like suggested in SM page 13-3 and they are simply awful

Look for suggestions ...

Re: CLC 1130 bad copies and printings

I assume, that you clean up the drum area and the sensors around the drum properly; also make sure that the primary corona is in good shape.
if so, you should detect if the error is drum or transfer related. Make a copy of your katun sheet enlarged to A3 and open the front door while copying is in progress, the maschine will stop at once. now release and slide out the transfer drum carefully and see, what is the picture on the sheet, also take a look at the toner image on the drum. I assume a transfer drum error, there is a transfer corona in the transfer drum unit (does not really looks like a corone, more than a wiper assy), take it out and clean it, if possible replace.
BTW: paper is not too moist?
second: these models have a drum heater, make sure that it is working

DRUM =40K

Replace Trans Drum Sheet/Attraction brush unit/Transfer blade unit
Grid Plate
Filters
Separation/internal and external static charging wires


this printer is history // i charge 225.00hr. just to look at one of these /

Hi to all again. Thanks to all of you for suggestions.
Here are the news

I've found the ext. static wire broken and changed it. Now the toner comes out well on the paper, but the copier applies - in my opinion - TOO MUCH toner. I have to make copies with "heavy paper" settings so the fuser rollers run slowly and fix the toner well.
Here are my new tests.

Take a look to katun test: the black is so thick that it is glossy; the central greyscale is not grey but light-blue and black; the other colors are just a little more dark than the original.
The other tests speak for themselves. In PG Tests 04, only cyan starts from the first row, the other colors are like magenta and they're all too thick and not in gradations.

The S.M. at page 13-60 says: "If dens graduation in 16 gradations is not noted as shown, suspect a fault in the laser system" !!
And what can I do in this case?

Is it possible, however, adjust in somewhere the density/concentration of toner that the copier must apply?

I believe you! We bought some years ago a CLC1100 modified to work with ceramic toners; it's difficult and costly to find its spare parts. So we have found in a Canon Center some old copiers: CLC1130 + CLC1150 + CLC900 + CLC700 + lots of spare parts for a total amount of $750.
Since a few months I'm trying to restore one of these (1130) to use it for internal copies and catalogs.

Thanks in advance for your help,
Barbara

Re: CLC 1130 bad copies and printings

u have over-saturation of toner/starter in units
an old DRUM will cause this


remove all developers>dump out all starter & vacuum out rest (make sure vacuum & it's filter are for this toner cleaning purpose)

put all door numbers back to orig. settings
add fresh starter to all units/ follow the developer replacement procedure

how old is the DRUM ?
what color is Drum surface ??

ok I will change soon toner/starters
the drum? I posted this photo last december
clc1130_drum copia.jpg
but I really don't know how old is it ...
last november this copier reported 313K TTL but now it reports only 61K ?!?
but its change costs too much for the internal work we do with it.

Re: CLC 1130 bad copies and printings

I imagine all drums of my old CLC's are a little bit mud;
CLC 700 (1) = 152K
CLC 700 (2) = 86k
CLC 900 = 158K
CLC 1100 = 142k in use w/ceramic toners
CLC 700 (3) = only 6K !! in use w/ceramic toners
CLC 1150 (1) = 415k
CLC 1150 (2) = not yet verified, It doesn't remain switched on - I don't remember error code and I can't be able to enter service mode 'cause it switches off in a few seconds; it has also the same corona wire broken and other problems I will try to solve in the future

CLC 1130 = mistery (313 or 61?)
now I'll proceed in this with toner changes to verify if there will be some improvements.

In any case your help has been always precious since I registered in last november!!
I'll post again after further interventions on my copier.
Thanks a lot.
