HP8000 Printer prints black faded streaks with content. Has New Toner.

[tonertonetoni]

I got a new Toner for my Printer Laserjet HP8000 and after several papers printed, it is now producing faded black streaks on the paper it is printing on and on the same areas. It is still printing the content, but there are black faded background streaks on it. What usually causes this so I can check it or clean it. Is it a major problem or is it because the toner was new? I have tried cleaning with the cleaning paper feature on the HP menu but still has the same issue.

I can not wait for it to clean itself because I use this printer for documtents to be sent.

the first question i would ask is;is it an hp cartridge or a remanned?i would say you could start a print from the manual feed tray and when the trailing edge is just entering the machine ,open it up and take out the cartridge and open the shutter and look at the drum and see if it has the streaks on the drum or if they are on the paper(paper should be at least part way under the cartridge).are the streaks fused on or do they smear with a finger?if it is on the drum or paper then it would most likely be the cartridge;it could be the high voltage contacts in the cartridge slot;try cleaning it out and the contacts on the side of the cartridge in the slot.otherwise it could be dust /toner on the scanner glass.you can clean it,carefully.if the streaks are present at that point and it is nothing else;it could be a high voltage power supply issue.

The streaks won't be fused to the paper until the paper goes through the fuser. By opening the cover when you were instructed by RAZ means that the paper never got to the fuser.

Now did you have this problem with the other cartridge?

Put the other cartridge back in and print.

Its a HP toner but I can't remember whether I bought a remanufactured or new from Ebay.

I did what you did, I went to print something and just as the paper was thru past the manual feeder, I turned off the machine and pulled out the toner and pulled out the paper.

The streak was halfway pass the paper so it must have just gone halfway before I pulled it out. So pretty much this is how it looked like. I pulled the toner out and the paper was lying flat at the bottom. Now the streak that was in there was smudgy, meaning it was just powder I presumed and hasnt been baked to become permanent.

Now what does this mean from the info I have given you. Should I do further tests? What should I do now. What material do I need, metholytated spirits, toothbrush, cotton. What do I need for a home repair job. Is this bad? Why would it be a power supply problem? I have a second HP so, I could probably get the powersupply from there which has done less prints. I wanted to use the other HP, but the Ethernet keeps on blowing up.

Everytime I place a working jetdirect network card in there, It just says loop something error and then the jetdirect card can never work again on any printer.

Don't know what's wrong with that, otherwise I would prefer to use that model.

Thanks for alll the help : )

the reason i mentioned the smuding ,or smearing when you rub it with a finger is to try to gather more info in case of the possibility that there may be toner buildup in the output ,past the fuser.but this would only apply to prints that have gone entirely through the printer.when you stop a print halfway and take out the cartridge,and the paper is sitting underneath there.none of the toner will be fused,because it has'nt gone through the fuser yet.thats the point of a half stop test.to see if the streaks appear on the page before it gets there.if the streaks are there at that point ,then it's probably the cartridge ;could be the transfer roller underneath,a dirty slot or scanner.now if you open the cartridge drum shutter(a spring loaded plastic door on the bottom of the cartridge),is there any toner on the drum?when you take out the cartridge,you flip it over and the door should just pull back away from the drum where you can then see it.when you let the door go,it will snap back into position.the high voltage power supply ,supplies the voltage to the rollers in the cartridge(thats why sometimes a high voltage power supply can cause this).there are some metal or copper tabs on either or both sides of the cartridge and also on the printer in the cartridge slot where it goes in.when the cartridge is put in,the tabs on the cartridge and in the printer slot come together and make contact.(i have'nt looked at the slot on this model in a while;there may also be a thin metal bar on the sides there for a contact );this is where the contact is made to the high voltage power supply and cartridge.if these contacts get dirty or one gets bent,so they are not making contact properly,it can cause this.thats why i mentioned cleaning out the cartidge slot and associated contacts.you can use a dry rag or something to clean the slot and sides of the cartridge.the scanner is on top of the printer under the top cover,you probably would at least have to take off the top cover off to get to the glass where the scanner shines through.if this glass gets dirty,it can cause this.people clean this in different ways;you can use a dry q-tip to do it.some use a camera lens cleaner or 99% isoprophyl alcohol.the idea ,if you do use a chemical,is to use one that leaves no residue when it dries.the only other thing i can think of is the transfer roller.when you stopped the printer and took the cartridge out;and the paper was flat underneath it.the transfer roller would be underneath the paper after you pull it out.this is a long spongy roller that goes across the path.does it look rough or old?this is a roller that is normally changed periodically with a maintenance kit because it will wear out after a time.i wrote quite a bit in this reply,but it is just to explain a few possibilities.often,in this case,the cartridge would be the problem;if you have another cartridge around that you can switch in;this is the easiest way to tell.if a different cartridge is put in and it goes away,then ,the issue is the cartridge.it is recommended to get a service manual for your model.it shows pictures and tells how to get to different areas and what the parts are on the printer.
with your other model ;it's hard to say offhand without knowing more about it;like the model and make of the priner and the exact error you are getting with the network card.if your IP address is automatically assigned by DHCP;the easiest thing to do is to do a cold reset with the card in and power cycle the printer and it will restart auto negotiation and clear any other anomalies.the things to do for this can vary from model to model.so more info on it would help.keep in mind that if the two models you have are different.you probably will not be able to use the power supply from one in the other.

i did'nt fully notice at first,because i was concentrating on what i had previously posted and replying again; , but thats a good question from redcow there;were you having this trouble with the previous cartridge ?did you change cartridges because of this happening?or did you just change cartridges because it was low and this problem just popped up after you installed the new one?this can make a big difference right off.
