Re: HP Laser Jet 2420d

What your seeing can be caused by several things, but I'd wager you've got either a leaky cartridge or just smudges on your print head. The print unit is in two parts and both will need to be cleaned thoroughly.

First, prep a work area with lots of newspaper and paper towels. You'll need cotton swabs (don't use cotton balls for this) and isopropyl alcohol.

Second, pull the ink cartridges from the unit (they snap out easily) and very gently clean the bottom of the cartridges with swabs soaked in alcohol until they come away clean. Dry the bottom of the cartridges with clean swabs and set aside on paper (careful, they can still leak).

Third, pull the print head assembly from the unit (most have a locking bar that has to be unlatched) and clean the same way as the cartridges. Make sure you inspect for cracks and/or obvious flaws (grooves or lines that shouldn't be there) that can cause problems.

Once everything is dry, put it all back and run the unit through a deep cleaning cycle and head alignment before doing any test prints.

Note: this type of maintenance is good to do on printers with a heavy work load after every sixth cartridge change, or if the unit has been sitting unused for very extended periods of time (more than a couple of months).

My HL2040 printer is printing black vertical lines along the right-hand side of the page, about 3" or so. A month ago I took it apart and cleaned the roller. Still doing it.

If the lines go all the way down the page, check the position of the corona wire cleaner tab (blue or green) at the top front of the drum unit. if not parked fully to one side it will create a solid black lines where it blocks the laser. Otherwise look for some other foreign object (or torn paper piece) that may be blocking the laser from the drum. If the lines are thin and shark, check for scratches on the drum (not repairable without replacing drum). If the lines are uneven thickness but in a pattern that repeats down the page every few inches, then the film on the drum is probably worn or wearing away and the drum needs to be replaced.

When i use the sheet feed on my hp laser jet 2840 to photocopy the printed page has a black line down it what can i do to get rid of this?

Clean the adf scanner glass. This is the thinner strip of glass that is just to the left of the large original glass. Just lift up the top feeder and look to the left side of the glass. Clean this strip of glass with a soft cloth and some glass cleaner. Sometimes whatever is stuck to the glass is hard to get off so keep at it till it goes away. Another tip is if the line is in the middle of the copy then the "spot" to clean is going to be in the center of this strip from front to back. If the line is to the left side of your copy then the spot is going to be towards the front side.
Good Luck and Than You for using Fixya

Verticle line down left side of page

Printers tend to have this problem if for some reason dirt gets trapped under the print heads. A standard head cleaning is the best solution, which can be found in the menu.
