Hp2420 problem There is a long vertical streak that prints top to bottom on the right hand side of my pages. Is there something I can clean or replace?

Hi,

Are the Streak lines vertical or horizontal ? Most likely it could be due to Toner issue, Try to remove the toner and clean it and re-install it

Replace the magenta image unit. Yellow image unit also and for the white streaks have the glass that cover the laser cleaned.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

Check to make sure the blade is UNDER the foam along the side where the streak is. If it isn't, then more toner is getting out than should be and that is the cause of your streak.

This is more than likely down to the upper roller in the fuser assembly. It's the heat roller at the back of the printer. The upper roller wears so paper dust and toner stick to the roller which then can get deposited back on to the page.

vertical lines on prints usually means either the drum's cleaning blade is not cleaning the drum (or the drum is damaged) or the fuser is scored. scored means that the protective coating on the fuser rollers is damaged. I would check the rollers on the fuser (the hot part of the printer right near the paper exit) for any lines on it, if you look at your prints, you should see them in the same location on the fuser. if you do not see any lines on the fuser rollers, then replace the drum.

check your ink levels. if its the ink that came with the printer it is probable running out of ink. they do not give a full cartridge with printers, only about 3rd full. also try cleaning the heads. and try changing your printer settings/prefrences to less ink, more drytime see if that helps.

Issue: Banded or streaked prints
Solution: Change the Print Quality Settings (Windows)

Change the Print Quality Settings (Windows) The Quality setting controls how finely ink droplets are placed on the printed page. Depending on the type of paper being used a higher Print Quality setting does not always insure a better print. Print speed will decrease as the Print Quality setting is increased. Follow the instructions below to change the print quality settings in the Canon printer driver for the Windows operating system through a printing application.

1. Click 'Properties' in the Print dialog box.
   
   Note: Depending on the Application software, 'Properties' may be displayed as 'Preferences'.
   
   
2. Set the desired print quality in the 'Print Quality' section.
   
   
3. Select 'High', 'Standard', or 'Draft / Fast'.
   

To set more detailed print quality settings, follow this procedure:

1. Select 'Custom' and click 'Set'.
   
   
   
   
2. In the Set Print Quality dialog drag the slide bar from 'Fast' to 'Fine' to select the print quality.
   
   
   
   Note: There are five options in 'Quality'. However, selectable options are limited depending on the media type.
   
   
3. Select 'Auto', 'Dither', or 'Diffusion' from the 'Halftoning' section.

it also may be the fuser

hmm this has happened before
make sure it is sitting straight and cleaning it might help

It sounds as though a cartridge is faulty. To determine which one, the easiest way is to run a page of text/block of colour through in yellow then cyan then magenta. which ever page comes out with the streaks on it will tell you which cartyridge to ditch and replace.
