Hp 3755 - I have been printing with only the black cartridge in printer. Now cannot get to print.

[K213]

Hp 3755.  I have been printing with just the black cartridge in printer wirelessly from my iPad.  Now I cannot get it to print.  The ink alert light is blinking.  The ink level icons show the black cartridge about 1/2 full but the color cartridge is blinking.  There is no color cartridge in the printer.  I also purchased a new black cartridge and when I put it into the printer the ink level icon shows full but all else is the same as other cartridge.  Thanks for any help.  K213

Hi @K213,

I'd like to help with the cartridge issue.

Try the below suggestions-

Reset the product

• With the printer turned on, disconnect the power cord from the rear of the printer.
• Unplug the power cord from the wall outlet.
• Wait at least 60 seconds.
• Plug the power cord back into the wall outlet.
• Reconnect the power cord to the printer.
• Turn the printer on. HP recommends plugging the printer directly into a wall outlet.

Clean the electrical contacts

Remove the cartridge indicated by the error message, clean the electrical contacts, and then reinsert the cartridge in its color-coded slot.

1. Turn the printer on.

2. Open the door to access the cartridges.

3. Wait until the carriage stops moving before you continue.

4. Remove the cartridge indicated in the error message from its slot, holding it by its side.

      CAUTION: 

   Do not touch the copper-colored contacts or the ink nozzles. Touching these parts can result in clogs, ink failure, and bad electrical connections.

5. Remove any protective tape that still might be on the contacts.

      CAUTION: 

   Do not touch or try to remove the copper electrical strip.

   

6. Lightly dampen a lint-free cloth with distilled water, and then clean only the copper-colored contacts on the cartridge.

   

7. Lightly dampen a lint-free cloth with distilled water, and then clean the electrical contacts in the carriage, located inside the printer.

   

8. Wait 10 minutes for the contacts to dry.

9. Reinsert the cartridge.

   • Insert the black cartridge into the right slot.

   • Insert the tri-color cartridge into the left slot.

10. Repeat these steps for the other cartridge, if necessary.

11. Close the cartridge access door.

12. If the error persists, repeat the previous steps to clean the cartridge and carriage contacts a second time.

13. Check for the error message.

Hope this helps! Keep me posted.

Thanks so much for offering to help.  Since I had been printing OK for some time I just assumed the problem was the printer.  I finally figured it must be the WiFi provider.  I called them and they set up a separate 2G network name (In addition to a 5G name) and now everything works fine.  They obviously changed something and did not communicate or I missed it.   K213
