Laserjet Pro 200 blue dots printing on page

[TownClerk]

still having issues.

Hi TownClerk,

Thanks for letting me know you are still having the same issue.

I need a little more information though, to assist you better.

We need to determine if it is a toner issue, fuser issue or a software issue.

Did you follow the Troubleshooting Print Quality Issues document?

What were the results when you ran the print quality page from this document?

Did it print properly?

If all the toners had the same results, it may be the fuser.

Make sure the printer is connected directly to a wall outlet. (don't use a power hub or a surge protector)

This ensures the printer is receiving full power and may help this situation. Will also affect the quality.

What kind of paper are you using?

Are you using Genuine HP Toner?

Thank You.

Hi All,

I'm having the same issues - blue and black dots, 27mm (just over an inch) apart, equally spaced.  I tried contacting support and they wanted me to give them $40!  Looks like nothing has been helping.  Was anyone able to find a fix??  This is crazy.

Hi @sjhgeary ,

I see that you are having the same issue. I would really like to be able to help you resolve this issue.

Please provide more information so we can try and figure out what the issue is. It could be a issue with the fuser or possibly the toners or printer hardware.

I am assuming you followed the documentation for running the cleanings, calibrating the printer and you are using  Genuine HP Toner, the toner was checked for toner on the drum and for damage. The printer should be connected directly to a wall outlet. (this can also affect quality issues)

What kind of paper are you using? Try a different type of paper just to rule that out. (plain paper)

Print a Diagnostics page and the Print Quality Page, if you can scan it and attach it, so I can take a look at it. That would be great. If the test pages come out clean, then it would be software related.

• On the printer, go to Setup, Reports, Diagnostics Page.

• Then go to Setup, Reports, Print Quality Page.

Provide the toner levels also.

What operating system are you using?

Please get back to me when it is convenient so we can quickly resolve this quality issue.

Have a nice day!
Thank You.

Hi @Gemini02,

I've gone through two cleaning cycles, recalibrated, and am using genuine ink. I'm at work now, so I can't get you the diagnostics sheet, but will do so later. I'm on a Mac with Mavericks, just updated firmware on the printer. Black ink is at ~90%, and CMY are between 30 and 50%.

I originally noticed the issue with my black ink. The toner was "low" (~30%). I replaced it and it seemed to fix it, but only temporarily. I'm now noticing it with my blue toner (now at ~40%) and also with the nearly new, just replaced black toner.

We've tried a variety of papers -- both thin office stock and a thicker stock for our holiday card envelopes.

Thanks in advance for your help and I'll try to get you those sheets later today.

I'm having a similar problem but black dots, not blue.  I've followed your suggestions for cleaning and making sure that the printer is plugged into the wall (no surge protector).  I'm using Hammermill Copy Plus paper (had same issue with Staples paper). I'm attaching photos of what is happening.

Hi @rdt-concord ,

I see by the screen shots, that you are getting black dots down the same area on the paper. Thank you very much for providing them. I will certainly do my best to help you.

It looks like a issue with either the black toner or possibly the fuser, since the dots are in the same area all the way down the full page.

1. Remove the toner cartridge from the product and verify that the sealing tape has been removed.
2. Check the memory chip for damage.
3. Examine the surface of the imaging drum on the bottom of the toner cartridge.
CAUTION: Do not touch the roller (imaging drum) on the bottom of the cartridge.

Fingerprints on the imaging drum can cause print-quality problems.
4. If you see any scratches, fingerprints, toner or other damage on the imaging drum, replace the toner.
5. If the imaging drum does not appear to be damaged, rock the toner cartridge gently several times and reinstall it. Print a few pages to see if the problem has resolved.

Please let me know the results.

Thanks for the suggestions. I did try inspecting the imaging drum surface, but can only see about 1/4 of it. How can I rotate it so that I can inspect the entire surface?

I happened on this thread searching for a solution to the very same problem. Too many people have this exact same problem for it to be something different wrong with each of our printers. There has to be something wrong with this model printer or some component in it. Have you found a solution?

[rdt-concord]

Elise1214 -- I agree. Seems to be a chronic problem.

Gemini02 -- Did you see my response?  I asked how I can inspect the non-visible ~75% of the drum last week and haven't seen a reply from you or anyone else at HP.
