Printer printing blues and magentas even in grayscale print

Post by nick6126 » Thu Mar 14, 2019 4:39 pm

Hello, today the printer started printing magentas and cyans even in grayscale photos, it looks like colored smudges.

I tried nozzle test, it looks fine, I did a medium cleanup as well for a few times, and also I did a few circulations of ink, but nothing helps...

Can you give me some advice? What should I try to do now?


Thanks.

Here is the test print:

And here is the printing result:

I also gently washed my print heads with the cleaning liquid, and soaked them as well.

Can it be the captop issue again (we changed them 6 months ago), maybe some nozzle on the printhead is clogged or something like that?

Thanks.

From the picture of the output, it looks more like the image is causing the output to look that way. The colour gain is likely because the machine cannot output the grey that is needed, change the artwork to a greyscale image and try again.

When I print just white, it prints normally white, but when I print something that has white in the design, magentas and cyans appear on the white areas... Black prints okay, Yellow as well, but White is the problem...

The same one I've been using for a year and almost 5 months... Nothing's changed since then, except the printing output.
