I have a HP Business Inkjet 1220 Printer, and the block ink cartridge light is flashing. I replaced the cartridge with a brand new one, closed the door, and black ink light is still flashing. I put in another neew black ink cartridge, closed the door, and same issue- black cartidge ink light flashing. I cannot print- what to do?

To reset the network configuration follow the instructions below:

1. Press the Configuration Page button once.
2. Press the Resume button three times.
3. Wait for about 20 seconds and then press the Power button to turn off the printer.
4. Disconnect the power cord from the printer.
5. Wait for about 20 seconds and then reconnect the power cord.
6. Press the Power button to turn on the printer.

Not sure if this will resolve other issues, but it's the only reset I know of.

I have the identical problem with an HP Business Inkjet 1100.

Once cartridges were past date, the printer would no longer print from Windows XP. It would however work perfectly from Linux.

I did not find an ini file as mentioned in other posts, and I really did not want to open the printer as it worked fine in Linux.

The following fixed the problem:

1) Click on Start button, run
2) Type in regedit, enter
3) Navigate to HKLM/software/Hewlett-Packard/HP Printers/HPWH Toolbox/Common
4) In the right panel, right click on Ink, pick modify
5) Change 0100 to 0000
6) Save and reboot

Please unplug your printer from the power source, wait for 2 minutes, and plug it in again. This usually solves this issue,

Warm Regards,

Selk

You can try using it and hope that it will work. If it doesn't then you will have to buy a new one. Don't worry nothing bad will happen to your printer.

All refill sets, come with a good description. But before you buy ink, make sure your cartridges can be filled and the chip can be reset. So you won't end with filled and unusable cartridges and dirty hands. Look here to see how things go: Ink Refill Kit For HP Officejet Pro 8610 8620 8630 8625 8615

Refill the HP 950 and 951 cartriges

You may be using non original ink catridges, the printer chip will not recognise so flashes as if needs replacing.if refills are original printer chip may need to be reset.

Put the old ones back in and see if the error code goes away.

readjust the margins in the printer page set up just before printing

HP print heads are usually a part of the cartridge so when you get a new cartridge you have a new print head. However, they do have a models with separate print heads. If after installing a good ink supply and cleaning/aligning the works, performance is still unsatisfactory you may have no recourse other than to change the print head which can be expensive to the point where getting a new printer is more cost effective.

Insert the old cartridge, if the message goes away the new cartridges printed circuit is defective.
