Color laser printer - colored specks on pages?

[usagora]

Anyone have this issue and know how to resolve it? I'm going to be contacting HP today (the printer in question is an HP Color LaserJet Pro MFP M283fdw, but I'm not sure how helpful they will be. The printer is brand new and heavy - returning is sort of a pain, so I'm hoping there may be a simple solution. For about a week I didn't notice any issues, but all of a sudden last week I noticed my printouts had magenta and cyan specks on them. Almost like someone flicked a paintbrush nearby and it splatted onto the page. The bizarre thing, though, is this ONLY happens on pages that have ZERO color on them. Pages with color on them print flawlessly, including the printer test page and supply reports. However, pages with NO color on them (all black and white or grayscale) more often than not have the unwanted colored specks on them. I've tried printing with color off (setting to "black and white only") but it makes no difference.

I've already tried the following:

• re-started the printer
• updated the firmware
• ran 3 cleaning pages through the printer
• removed each toner cartridge and rocked them back and forth before replacing

None of those steps resolved the issue.

That's not software, that's the printer cartridges themselves. Most likely the PIP roller (greenish roller) is damaged on the colors shown. It's either that or the PIP on Magenta and Cyan is not completely discharging during B/W printing.

The greenish roller is more commonly known as the drum (for the benefit of others reading this). Seems amazing to me that two brand new genuine HP toner cartridges could both be faulty out of the box, but I guess it's possible. I didn't have time to call HP today, but hopefully tomorrow. Hopefully they can send replacement toner cartridges for free since the printer was purchased just recently brand new directly from HP.

Agreed, I work on the HP Indigo platform and that type of issue is normally either physical damage or electrical issues.
