try to replace the defective cartridge by a new one and see printing test result

During printing, the HP product makes unusual or loud noises. You might describe the noise as grinding, squeaking, or screeching.

Step one: Clean the rollers in the back of the product
1. Disconnect the power cord from the back of the product.
2. On the back of the product, find the rear door.
3. Squeeze the tab or tabs on the rear door, and then pull the rear door toward you to remove it.
4. Open the rear door on newer Photosmart, Officejet, or PSC productsInside the back of the product, rotate the paper rollers with your fingers to make sure that they can turn freely.
5. Rotate the rollers located on the inside of the rear door to make sure that they can turn freely.
6. Remove any torn pieces or scraps of paper that you can see.
7. Dampen a clean, lint-free cloth or swab with distilled water, and then wipe the paper rollers inside the product and on the inside of the rear door clean. Rotate the paper rollers with your fingers to clean all the way around them.
8. Reattach the rear door. Make sure that it snaps into place.
Step two: Clean the rollers in the front of the product
1. Lift the cartridge access door to access the front paper rollers in the product.
   NOTE: On some Officejet models, you might need to close the document catcher. Then, look in through the front of the product to access the front paper rollers.

I have seen this before but it has not caused the black to run out quickly. if you look into the machine you will see at one end of the platen roller it will be swimming in ink. As the paper passes over the roller it will deposit ink to the back of the paper. now why is the ink getting there? Well its just possible that air hole in the cartridge is blocked but you say you have replaced the cartridge. Ah but with what? are you using recycled cartridges? they may be filled with ink and not dye which is what originals use. Dye is much thicker than ink and ink maybe leaking from the cartridge. The seal in the carriage may not be making a clean contact with the base of the black cartridge causing it to leak when the carriage is moving. Check those out and repost if still having the problem.
Good luck

black vertical lines on the printout comes due to some reasons.
1) if the black cartridge is near to its end it will give black lines instead of proper printing.
the cartridges gets over many times due to head cleaning and deep cleaning.in 3-4 cleanings cartridge gets over.in one cleaning 4 ml of ink gets puled out of cartridge.the whole quantity of cartridge is near to 25 ml.
but if the cartridge is full then the problem is of cartridge head .the head is the part in which you insert the cartridges if the head is got blocked internally to its holes from where ink comes out.then there are two methods to clean the head one is head cleaning which you did.the other is removing the head by disassembling the printer and then cleaning the head manually with isoprophyll liquid.but its a time consuming and tough job.a local printer repair center will be advisable,
and in some cases it has seen that cartridge gets air pressure problem inside and due to that it leaks inside the printer so replacing that cartridge solves the problem.also many times the cartridge gets leaked and that leaked ink gets collected and stuck up on the roller of the printer from where paper passes so the strips of ink gets printed on the paper.in this case no head cleaning but cleaning the internal roller of the printer with tissue paper helps.the procedure is called servicing.that can also be done at local printer repair center.or you can do it manually by using tissue paper.but to service whole printer it needs to be disassemble.
check out his option.thanks.

It means ink is backing up on the rollers, it is waste ink and should be going to the absorber, but some models have the ink drying up and plugging the passages. You will need cleaning, new ink absorbers, and a mylar strip that will keep that from happening in the future.

The rollers jst need a good cleaning. If you don't know how to service the printer, take it to your local service agent for cleaning.

The roller cleaning will require you to remove cover to clean the full roller with alcohol to remove ink build up. Have you tried to just run/feed a blank piece of paper through to see if you have roller ink roll off?

This also sounds like a bad cartridge with clogged jets...

Most likely you have a leaking print cartridge (toner cartridge). Does it have the same problem if you use the Manual Bypass tray?

It could also be a worn fuser sleeve that is causing the print defect...the fuser would need replaced in that case.

Unscrew the housing screws. Take a piece of paper towel saturated with denatured alcohol and twist the towel, blot up ink

Hi , clean both end of roller clean rug or cotton tip , this may happen during cleaning time some ink expose both end of roller sometime in piece of paper .during the cartridge in the middlle pullout the power cord stop cartridge and push cartidge down and lock.
