HP 3600 dn Calibration Problems

[redinger]

I have a customer with an HP 3600dn.

At times she will be printing a letterhead document and her company's logo, which is black set in a clear object box background will print with a cyan background. If we run a forced calibration the problem goes away and the object box with the logo does not print with the cyan background.

Driver has been reloaded, the latest firmware is being used. The operating system is Vista.

Is geniune hp toner being used?

[redinger]

No. But that should not matter. If you think that it makes a difference, please explain.

I had one that it had non hp cartridge that did the same thing, and it would also leave smudges on copies after a few prints. I thought it was the transfer belt unit(need to check its life counter). Replaced it and problem came back. New geniune hp and problem gone. I did notice that drums in Hp were of a different material and color than nons. I am not an HP rep so please dont think I'm promoting that. I just had a similar prob and tossed out what I found. seems my printer was real finicky.

with any of HP's color laserjets, DO NOT mix cartridges. Either use all OEM or all Third Party. It will affect the image quality. There are some good third party cartridges out there, but you may have a defective one. Even a new OEM can be defective.
