Want to clean the jets of cartridge, help required

Hi
Re-check your cartridges installations.
Clean the cartridge contacts
Try cleaning the 'printhead'.

Unseating and reseating the cartridge
Turn the unit on and open the lid or top cover.
Remove the cartridges.
Re-insert the cartridges.
Close the unit’s lid or top cover.
Cycle the power to the device by turning the printer off for a few seconds.
Turn the printer back on.
Print a test page. If this does not solve the problem, proceed to the next section.
Wiping the cartridge contacts
Turn the unit on and open the lid or top cover.
Remove the cartridges.
Using a clean, dry lint-free cloth (a coffee filter works well), wipe the cartridge contacts, from the top to the bottom (see Figure 1). The contact area of the cartridge should be rubbed briskly to remove the waxy lubricant material from the gold contacts.
Figure 1: Cleaning the cartridge contacts

The contacts inside the printer may also require cleaning. Using a clean, dry, lint-free cloth, gently wipe the contacts, from the top to the bottom (see Figure 2).
Figure 2: Cleaning contacts inside the printer

Re-insert the cartridges and close the printer’s top cover.
Print a test page. If the problem persists, perform a hard reset as described in the next section.
Performing a hard reset on the unit
When the printing unit detects an issue with the cartridge, a software flag is set inside the device. This flag may not reset until performing a hard reset on the device.
HP Deskjet and Photosmart printers
Verify that the unit is switched on.
Open printer and remove both cartridges.
Unplug the power cord from the printer.
Wait 30 seconds.
Plug the power cord back into the printer.
Open the top cover and reinsert both cartridges.
Turn the unit on.
Print a test page. If the problem persists, the cartridge should be replaced.
HP Officejet and PSC all-in-one
Verify that the unit is switched on.
Remove the power cable from the back of the machine.
Wait 30 seconds.
Press and hold the POWER button on the front panel.
Reinsert the power cable in the backside of the unit.
Print a test page. If the problem persists, the cartridge should be replaced.

Run a few "print-head-cleaning" cycles, to get the black ink flowing through the ink-jets inside the print-head.

Some printers REQUIRE an "alignment" step every time you change the ink-cartridges.
It only takes a few minutes, and it prints one or two pages of paper.

You have blocked jets in hour cartridge, Try running the cartridge cleaning utility that should be part of the printer software, if this does not work try leeching the the jets clean by holding a piece of tissue paper over the jets, as a last resort stand the cartridge in a saucer of hot water for a while. Run the cleaning sequence again and hopefully you will have a clean print.

Check that the jets are clean as it sounds like there may be a restricted flow of ink - assuming that there is sufficient ink in the cartridge. Try printing the test picture in the HP Printer Asistant software. This requires black as well and a lack of black would show up. If the black cartridge is full and you suspect that the jets are blocked, try leeching the jets clean by pressing a piece of tissue paper over them. If that does not help stand the cartridge in a saucer of hot water for a while, wipe off the bottom of the cartridge and try it again. There is also a cartricge cleaning sequence in the HP Printer Assistant probram

The printer cartridge could be
1) Out of ink and need to be replaced/refilled
2) The jets at the bottom of the cartridge may be clogged
3) Their could be a bad connection from the cartridge to the pads on the flexible circuit board in the printer.

To try and clean the printer cartridge I have heated a wet paper towel in a microwave oven and set the ink cartridge with the jet are in contact with the hot towel. That sometimes will clear the jets. If you see ink on the paper towel the jets are flowing.
Run the printer software to run the cleaning program and see if you get black bars on the paper. If not there is either not enough ink or there is a connection problem. Sometimes the connection problem can be fixed using a cotton swab in alcohol to clean the contacts on the cartridge and the flexible circuit in the printer. Be very gentle if you attempt this cleaning.

Have you tried the "clean cartridges" button in the Printer Htoolbox? Also,does your color cartridge have ink? If the "clean cartridge" option doesn't work, take the cartridge out of the printer, put a small amount of hot water on the paper towel and push the paper towel up against the cartridge ink jets. This often opens up blocked ink jet ports. Dry the cartridge with a dry paper towel and put it back in and give it a try. You don't need a lot of water, just enough to get the ink flowing. Hopefully this will help. Good luck!

If the lines are black, the cartridge probably has bleeding jets.

If the lines are white (unprinted) then there are plugged jets.

In either case, replace the cartridge. You can try cleaning the jets by wiping with cleaner... Using the "cleaning jets" function of the printer is USUALLY futile.

Remove the cartridge.....
using a cotton bud clean the ink nozzle area on the cartridge for excess ink..take extra care not to damage the nozzles

... while at it take a piece of rag and try to clean the..service station area(this is where the cartridge goes to the side of the printer)for ink build ups....try to clean the rubbers that wipe the ink off the head as it runs across ..this is near the service station area clean well

it just requires cleaning..try to use little bit of cleaning solution that is available for that particular model..if not use bit of alcohol but do not use it on the cartridge itself ..make sure the alcohol is properly dried as not to damage the head

do reply if this helped
