Have Bizhub 65HC overloaded with impressions of yellow.
Very yellowish skin tones. Gamma, ICB, PRCB, IC304 were exchanged. Problem persists.
Somebody help.

Re: Bizhub 65 hc loaded with yellow.
You haven't mentioned if the following has been done
Printer Gamma Offsett Adjustment for the screen being used
Printer Gamma Sensor Adjustment for the screen being used
Print Controller (IC304) calibrated on the stock you are trying to output.
What do internal test prints look like? Try outputting test pattern 53 with CMY set to 100 and K set to 0. Check if output is dominant in yellow.

Re: Bizhub 65 hc loaded with yellow.
Sorry Mick01pela delay in replies.
I have done printer gamma adjustment and printer gamma sensor adjustment. It's a C65hc and work with approximately 15 C6500. HC is the first.
Print test 53 with 90 (0 ~ 255) CMY and 0 (0 ~ 255) K. The yellow predominated.
Here in Brazil, we adopted DOT1 default. Printer Gamma Offset Adj. it is
with C, M, Y & K ending between the two lines as service manual.
The values are:
Y -12
-7 M
C +2
+5 K
based on PM200k kit, kit PM100K, Drum's and developer's all new.
Thank for help!!!!!

Hi,
Dot 1 is a good overall screen to use. However it can be dominant in yellow on cetain colours and files. Can i suggest that you set up Line 1 (gamma Offsett) and check the output. You should find this is a smoother screen.

I found that the prints are very yellow when left on the old Dot1 screen type when the new screen type is implemented the colour (yellow) is changed (for the Better)
