Hi @Satya49,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

I'm sorry to hear you're having trouble with your HP printer. Here are some steps to help resolve the issue of black lines appearing on your printed pages:

Please try the steps shared below and let me know if this helps.

Please remove the Cartridges from the Printer if possible, and try a Hard Reset. Do keep us posted to help you better

** Hard reset :
1. Turn the printer on, if it is not already on.
2. Wait until the printer is idle and silent before you continue.
3. With the printer turned on, disconnect the power cord from the rear of the printer.
4. Unplug the power cord from the wall outlet.
5. Wait at least 60 seconds.
6. Plug the power cord back into the wall outlet.
NOTE: HP recommends connecting the printer power cord directly to the wall outlet.
7. Reconnect the power cord to the rear of the printer.
8. Turn on the printer, if it does not automatically turn on. The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
9. Wait until the warm-up period finishes and your printer is idle and silent before you proceed.
 

HP Smart App: Please uninstall the HP Smart app --> restart the Device, Wi-Fi router and printer --> install it back and add the printer.
 

Firmware Update: Please update the Firmware from the link. This will help with how to update the firmware on the printer or devices

I hope this helps.

Take care and have a good day.
