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.

Hi Everytning I print has a very narrow pink line straight down the centre of the page, also every so often the print has a black/yellow/blue/pink thick line running across the page. Thanks


The narrow pink line is coming from your magenta toner/drum cartridge. You may be able to open the from cover and look at the 4 toners. If you look at the magenta (like pink) cartridge, you might see the thin line on the drum surface.
The multicolored band that sometimes shows up on your prints is most likely the transfer belt unit. This is caused by an area of the belt that is not being cleaned very well. This probably tends to show up when you are running mutilple prints of a page.
So it looks like to may need to replace your magenta toner and look at getting a transfer belt unit.

There is not clean cartrige button.
If you want you can try to remove the cartridge and clean it with a paper towel, and see if that helps get you to 300 more sheets, if not I would replace it.

Hp 4600 no cyan printing


Firstoff, if you have tray 1 set to "any size" & "any type" they had problems with it going into calibration to frequently. If you upgrade the firmware this will take care of that. As for no Cyan, check the scanner interlock to insure it is opening the scanner cover. You could also go into diagnostics and disable cartridge check and swap the cartridges around, ie. cyan & magenta, run the print quality pages and see if the problem follows the cartridge. It could also be HV power supply.

It should not, when you say pink you mean Magenta right?
sounds like it needs some cleaning, pull out everything you can pull out from the printer, and carefully clean any tone you see inside with a dry cloth, also clean the cartridges themselves.

print a few pages for any remaining toner to get phased/cleaned out on the print outs and see what happens

thanks for rating
