task alfa 4551ci print quality

[n25an]

I have an issue... if you print all the internal prints... they look perfect...
if you send it from a pc the blues look greyish...

I am thinking of replacing drums and developers...

but I have a strange feeling its a print driver problem...

I am checking with you guys here to see if anyone faced a similar issue on a kyocera...


no background nothing strange... it just prints a bit off... greyish...
there is another kyocera copier a 4052ci and the colors come out perfect... when you print...
regarding the 4551ci customer showed me a print from last week and the blue was reddish...

I ran grey scale and calibration and did drum, developer refresh and laser scanner cleaning... color still greyish just made the prints overall more vivid... but blue still greyish...

make sure you using updated drivers and current firmware. Go through and make calibration, tone curve adj and ect. And see what effect it dose for you

If internal prints are coming out fine, it is not a print engine problem, ie drums/devs. As already suggested make sure you are using the latest print driver. Is the off color printing coming from one user or multiple users? If it is one user, check to see if that user has not changed their color profile in Windows or the program they are using to print the color pages. Print driver/program settings will over-ride and default settings in the unit.

Compare the print from USB to the print from PC. Samples? =^..^=

Look at the customer with your eyes crossed and say 'looks fine to me'.

I often do an image adjustment or color calibration when ever I visit a Kyocera machine. Definitely whenever I have to crack open the machine.

An easy way to do color calibration is to go to U952 and do the Setup list. U952 lets you do calibration in the right order without have to hunt around for the steps.

Also, when you get a drum, developer, fuser, or even a maintenance kit, there will be an A4 sheet with the title Details of adjustments following unit replacement. The second part is Image adjustment. Before I started using U952 I would follow the image adjustment when ever I deep cleaned the machine or optics or changed or cleaned the charger roller(s). I keep a copy in my tool kit. I have also attached a copy here.

With many of the quality problems that I have come across with these machines, doing the above first has saved me a ton of time and keeps the customer is happy.

We tend to forget with all the microprocessing that going on in faster and smaller CPUs on the equipment, how difficult the xerographic color processes really is. There's a lotta stuff going on.

GREAT!!!

Now, could you please enlighten the rest of the class?

[Samanator]

Yes, inquiring minds would like to know.

Is it a secret??

when asking for advise, and the problem was solved, it would be nice if the OP would:

provide samples of the issue

when finding the 'fix' PLEASE post the steps taken to clear the issue.

when people provide rational advise, the OP should like/thank the commentator for the suggestions ( boosts reputation power ) *** this is the way the OP gets points also ***
