Bizhub C3351 print outlines

[Bix]

hi, to a client I inverted a bizhub 458 with a C3351 because they changed office. We also changed his drivers. But I have an anomaly: on the bizhub 458, when they print in black and white, images with a transparent background have no problems. When they print on Bizhub C3351 in black and white, the image has a kind of outline.

In the driver I tried to set maximum photo quality, but unfortunately without success. In the driver I don't know what to try to see. One attempt I could make was to change the door to the 458 driver to see what was going on but I forgot to do.
Someone for some advice / experience?

If you installed the PS driver, try the PCL or vice versa

Post a sample for us.

If it's got an outline, it sound's like the Alpha Channel of the "transparent" background is being knocked out and not flattened! Save/export whatever document/webpage it is as a PDF or use Bullzip PDF Writer....let me know what happens.

PS--almost sounds like a "halo" or "drop shadow" effect!!!

That's right, that's what happens.


Unfortunately the problem comes from a management software,
When they print in other ways, it doesn't come out.
With Outlook it exits again.

Sounds like the picture/ graphic may be a .png, in which case, they can convert it to a .jpg with a solid white background unless of course the graphic has a text flow around the object! Have you tried exporting/ saving in a flattened PDF format before printing?

Thanks for the support,
These are ideas that I will consider.
I still don't understand why on 458 this doesn't happen. In the case, I'll let you know in case of updates.
