BH-C-253, slight shift in color.

[Hansoon]

In the below scan of a print out there is a slight shift of the colors in the direction of the leading edge towards the edge of the colored fields marked with an arrow.

At the left customers machine BH-C-253 and at the right my showroom machine BH-C-353.
Compared to my own C-353 it looks as if the colors on the C-253 are slightly gritty, a little less saturated and shifting towards the leading edge with increased saturation, best seen in the red color. Fresh setup and calibration has been done before.

Any ideas where to look please?

I had to look hard to see it in there, but I see the line going down the page, slightly lighter.

How do the C,M,Y,K Halftone patterns come out?

With a c253 I would guess maybe a possible print head issue.. Those that replaced them before know all too well their failure rate.

Don't think that is a writing issue. Did you change any IU's? I have got a customer that runs full coverage prints and if that happens i change the IU's.

be glad your getting prints that good...


machine is not production. I would not expect it to act line one...


For daily office prints, its great. If your using it for pay for print. May not be a great machine.

This A/B comparison seems to be a complaint on a high level. Saturation usually improves if you switch to color copy paper. And there are other variables to consider (moisture/temperature/pm yields/age of the units....). Still this is probably a case I'd try to talk out.

Fuser

Try 200GSM PAPER and see if it improves
Take your ITB TR FUSER from your 353 and see if it improves by changing fuser first then ITB & TR, this way you going to check your long term consumables.

Life of IU's? After that I'd look at transfer roller.

Re: BH-C-253, slight shift in color.

IU's are 50% for all of the colors and 80% for the K unit. TB is 80% and the fuser 90%. That's why I am puzzled.

Brand new and not chipped?

After several calibration and stabilization sequences the prints became just as good as those from the showroom machine. Weird, but OK for the moment.

Thanks for your help guys.
