I would suggest you try cleaning one more time. Clean the printhead properly. If the issue persists, the issue is with the printhead and you may have to get the printer repaired.
If so, please contact a local printer repair shop, check the printer and if it needs repair, please ask for the cost of the repair. And only if it is worthy, please get it repaired.
Unfortunately, except for business-grade workgroup printers, few modern printers are repairable, and fewer are worth repairing.
Most printers are now manufactured to a "replace not repair" standard. To understand why this is the case, consider the cold, hard, real-world cost of repairing a printer.
I apologize for the bad news. However, this is the honest answer I can give.
