HP 3005dn prints black horizontal lines on page from top to bottom - new toner cart - so what's my problem

If this a P2035 printer using a toner cart with a drum in it. The drum has been exposed to light or has a smudge on it. take the cart out and look at the drum. This is a round light blue tube located at the bottom of the cart. It is the drum because it is the only thing in the printer that will print a defect three times on the paper. You could also print about 0 black sheets of paper through the printer and it will go away. This is because the drum coating is in layers like an onion. You must get rid of the exposed layer to get to on that has not been exposed to light.

Hi Donna

It sounds like the machine still wants a new black toner, normally this message clean fuser input" clears whent he machine reconises a new Original non refilled cartridge being fitted, so it sounds like you have either a faulty cart or a non gen HP cart fitted like a aftermarket or refill. People often get confused that a cart they are using is OEM when in fact it is a OEM empty that has just been refilled or it isnt HP at all usally marked as "for use in HP" so please ensure we are in fact fitting real toners, if you fitted a HP one you would have to tear open the box it comes in.

If it was call I would unplug it from your pc, power it off then on, remove all your cartridges and ensure they are original HP, I'd remove the fuser and clean the discharge lamp area see HERE.
Id replace any consumable that look suss or was leaking. I test via the control panel ie menu/ information/ print supplies status. Can you get a status page out or does the error stop you?

If it still failed the first thing to do would be to replace black toner cart with another as I think your is faulty. If it is real HP then is a gaurantied item so take it back for replacement.

If a tec was their just 3 days ago it too should be covered, most companies like mine allow recall warranty on repair work on same fault if it occurs within 30 days or original call.

Here your user manual and a pic below of what it wants cleaned but mind you normally a new toner clears the message regardless, please note this error wasnt included in original machine realease it was a firmware update that added it so it may not be listed in early prints of manuals for your machine.

Let me know how you go the more info the better

Cheers

I'd start with a new toner cart. then the fuser.

While the line is showing up on the output pages.
Stop printing and put paper in the manual feed tray (tray 1).
Start printing again. As a page gets pulled into the printer about 1/2 way open the top cover.
Pull out the toner and look at the page inside the printer. If it doesn't have the grey/black line, get the fuser replaced. It is defective.

Pull out the toner cart and look at the drum....it should be clean. If it is clean, you have a worn out fuser, if it's dirty you need a new toner cart.

I assume you had the issue before you changed the toner, If so the problem is either the fuser or the Laser.
Do this:
start a print job and after you hear the paper feed into the machine open the top cover to stop the machine. You want to stop the page before it gets to the fuser. May take a couple tries.
remove the toner cart.
the page should be under the cart with the image on it.
If the line is on the page the problem is image development(toner or laser).
If no lines the problem is likely the fusing assm.

Image defects on LJ printers are usually the toner cart. or the fuser:

This is the test to determine toner or fuser issue.
Print a test page
When you hear the paper feed into the machine open the top to stop the machine
Remove the toner cart.
You should be able to see the page with printing on it. (This is before the page hits the fuser)
If you can see the image Defect on the page the problem is most likely the cartridge but NOT the fuser.
If the page is clean the problem is most likely the fuser.
Hope this helps

Hi,

Black vertical lines could either be a scratch on the drum or a dirty charging corona wire. Order a new drum and clean the Corona with a brush. Image of Corona This should resolve the issue.

You need a new Toner Cartridge

Toner issue getting to drum - use gen toner cart.

or Drum blade stuffed (lines are down page fro top to bottom- replace drum assy

Drum has been exposed to light faint or blank across copies repeated 4 times down page - replace drum assy

or upper fuser roller stuffed, down page, smudgy print -  replace fuser

LSU(laser) or boards rarely cause issues
