    Same problem. Every time I print, I get three equally spaced black dots that appear vertically on the right side of the page! Anyone know why?

  • krn_yoder Aug 21, 2008

    Same here! Three dots. Started out with the left side, and now the right side as well. I've had this printer 3 1/2 years, and this just started with my last toner cartridge. I changed the toner cartridge, and the problems is still there.

Funny, I had the same thing. I took out the drum unit and removed the carrtridge, then slowly turned the drum, using the gear wheels at the end. Eventually I noticed a pale dot on thge surface of the drum, just about where the dots were appearing on the page. I sprayed some general-purpose (keyboard-type) cleaner onto a paper towel and carefully cleaned the drum surface, although the dot I removed very carefully with a fingernail - the cleaning fluid had softened it. So far it is printing OK, so I guess something is getting deposited on the drum, which will need to be cleaned periodically,

Hope this helps

Have you tried cleaning the corona wire on the drum unit (the blue slider bit)?

Replace the drum unit (assuming you have already replaced the toner cart?)

To check the remaining drum life press the go button 3 times. A report should print out with the info on. Even though you may have some remaining life, the drum can fail early.

If the dots/marks are repeating about 3 times down the page it is almost certainly the drum unit that has the problem.

I'm printing in high quality on glossy II paper and the printing is fine but it looks like the photo is made of dots. if you look closely you can see dots. thanks!


Haha Sorry to laugh but all printing is done in dots... my guess is the print quality is turned way down like maybe 300dpi x 300dpi o btw dpi is dots per inch so basically just need to checkout the printer properties and turn up the quality or dpi

I have a Brother MFC 8460N that prints three black dots down the right side of each page when going through the printer. I have tried cleaning and it does not work. The black dots show up on copies as...


Measure the distance between the dots and that will give you the answer to which roller is causing the problem I believe the Drum is the only roller large enough to just cause three dots.

Consistent dots down print


Try to print clean page ,
Print a cleaning page During the printing process, paper, toner, and dust particles can accumulate inside the printer and can cause print quality issues such as toner specks or spatter, smears, streaks, lines or repeating marks. Follow these steps to clean the printer's paper path.
  1. Load copier-grade paper (not bond, heavy, or rough paper).
  2. On the printer's control panel, touch the Menu button.
  3. Touch Configure Device .
  4. Touch Print Quality .
  5. Touch Process Cleaning Page .
A Cleaning message appears on the printer control panel display while the cleaning is taking place. The cleaning process takes a few minutes to complete. Do not turn the printer off until the cleaning process has finished. A page will be printed when the task is complete. Discard the page. You might need to repeat the cleaning process to thoroughly clean the printer. Print a few more pages to see if the problem is resolved.

Black dots are printing on the left hand side of the page when I print from my hp laserjet 1015. Any ideas how to fix this?


Run a "half test". Put paper in the manual feed tray. Print anything. Watch the paper, when it feeds about 1/2 way into the printer, open the cover. Pull out the toner and look down at the paper. If it has the dots, replace the toner. If it doesn't have dots, the fuser is probably bad.

How do Print a scanned image


This is a complicated issue. You have to understand the computer term DPI, which stands for Dots Per Inch. This applies in three places:
  1. when you scan, you can set this
  2. when you display it on your monitor, your monitor will be usually 72 DPI or 100DPI depending on what resolution your video driver is set to
  3. when you print, it depends what resolution your printer can print at. Your printer can also stretch the image onto the paper by duplicating dots as needed.

Dots = Pixels
In PixWizard, we show you the image size in Dots.

Let's assume you scan at 300 DPI. You scan an 8x10 picture. This is saved as 2400 dots (8" x 300 dots/inch) by 3000 dots (10" x 300). Let's assume your printer is 600DPI. In dots, this is 4800 (8" x 600) by 6000 (10" x 600). For best results, you should scan at 600DPI and set the print options to use a 1:1 scale when printing. Our programs can also stretch the image to fit the entire printable area of your printer.

HP Color LaserJet CM 2320nf MFP has black dots on the right side of the paper. I have calibrated, and used the cleaning mode and it is still happening. Can you help me?


Put some paper in the manual feed tray(tray 1).
Print something.
When the paper feeds 1/2 way into the printer, open the cover. If the paper has the dots it would be caused by the toner or the image transfer belt. If no dots, the problem is probably the fuser.

By any chance did you vacuum out the printer. The dots could be coming from the paper path if it is dirty.

It prints three dots on the left side of the page every time.


These dots may be called as "Garbage Valley"
This means ur printer has got lots to print but it was stopped due to certain reason.
I'll ask u to go through ur printer manual & print atleast 5 pages of garbage valley & while u do this, i'll ask u to reinstall ur printer driver.
Hope it works out.
Thanks
