Bizhub C 352 Data clear

[zalim]

Hello everyone,


I have been having trouble with customers machine, after doing the data clear and error clear now its not printing BLACk anymore instead printing in Blue.
When i send a print from computer it prints perfectly but when i try to copy it using glass or adf its printing in blue everywhere, where BLACK supposed to be.

Any suggestions or tips?

Thanks in advance

Re: Bizhub C 352 Data clear

you must have wiped out the copier default and changed black only to color, all you have to do is change it back to black only on the screen, that should copy in black only. then make it black only as your default and anything else you need, then do the following:

press utility/counter key
touch #2 User Settings
touch #3 copier settings
touch Default Copier setting
touch current settings
ok ok close close

then your set.
good luck

Just out of curiosity, what exactly did you expect to fix by doing a data clear?

Most times all you end up doing is adding new problems to your list of things to fix. =^..^=

Re: Bizhub C 352 Data clear

but where can i change the setting back to BLACK only? from service mode?
thats what i have been looking for but i cant find it plus there is no default setting option in utility>user settings>copier settings> i cant find any default setting here !

I was trying to fix a problem with Start button, which is fixed but as you said there is a problem with color now !

the option to select current setting is in intial setting, is that what you meant?

Select Black & White copying. Go to that location and select Current Setting. That will lock in the current choices as home settings.

but that will also print color orignals all black,

my problem is, when i put a colored original on glass which contains colors like red, yellow, green, blue, black etc etc , it simply doesnt print black in that color copy,
it prints all the colors but messes up the colors which contains BLACK in them, it prints BLUEISH (more like cyanish) instead of black

Did you run the gradation adjust? If you ask "how do you do that", then you're either not a tech or you don't have the necessary documentation (or both!).

lol i am a tech !

I did all the steps mentioned above, before i came here, they didnt work thats why i came here
I even have all the imp. documentation i need.

Did data clear,
thn i noticed the problem with blue replacing black.
I selected current setting from user settings>intial settings
to keep it print BLACK, it prints black but only if BLACK is selected and it prints all in black thn.

Selected auto color to copy a color original and it DIDNT WORK ! black simply wasnt there.

Checked my gradation settings, it was all 0 so i did gradation settings (gradation adjust)
still didnt work !

Thn i tried image stabilization, checked color regist (all of them were within -5 and +5 so nothings wrong there)

thn i looked for this problem in service manual but coudnt find anything so i came here for help

Re: Bizhub C 352 Data clear

When you say "black isn't there", you mean that, on a color copy, there isn't any black present? Not only a little?

On colour prints, does black appear?

And what if you scan a color original? Does black appear on the scanned PDF/TIF?

correct,

well on a color copy all colors have BAD quality and rough and no there isnt any black there, the other dark colors are very rough also, the darkest one is blue/cyan.

When i send a print from computer, the quality is perfect, the way i want it to be, when i do gradation adjust i print internal pattern and they are looking good as well but when i COPY from glass/adf, the quality becomes bad, when i select BLACK only it prints black only fine but when i select AUTO color, the full black copy turns BLUE and color copys show no black instead BLUE on its place.

Yes black appears on Scanned PDF/TIF.

Re: Bizhub C 352 Data clear

perhaps you could post an example of the problem, it might make it easier to diagnose..

Re: Bizhub C 352 Data clear

Sounds like a problem with the scanner then,
I hate to point out the obvious but have you cleaned all the mirrors and glass?

[Albonline]

Re: Bizhub C 352 Data clear

you say you ran gradation, did you do the 3 of each thing? did it complete without errors?

[zalim]

Re: Bizhub C 352 Data clear

@kingarthur, ok i will scan it and post it here

@gaffers all done, all mirrors are cleaned perfectly, did it not once but 3 times already

@albonline, in gradation adjust there are like 3 options

i selected the first one, printed out the test pattern (it came out in A3), thn i put 10 A3 paper on original and lowered the orignal cover, values were all 0 but afterwards it was showing me values again, i did the same with 2nd option in gradation adjust ( i think its resolution mode) did same with it and after that with hight compression mode.

in Resolution mode it showed me an error but it was because the paper wasnt place on glass properly so i fixed that and after that it went smoothly.

Now I thing i am not very sure about, am i supposed to repeat the same step 3 times with each option in total 9 times? or just 1 time with each option in total 3 times ?
