INK PROBLEM
Inkjet printers need to be used frequently to prevent ink drying out and blocking the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages, then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer than replace the print head.

Some times the printhead contacts simply need to be cleaned.

Remove the cartridge and use a small amount (just enough to clean any foreign materials)of rubbing alcohol on a q-tip to clean the contact areas on both the cartridge and the printer.

Take care to not flood the contacts with the liquid.

Reset the cartridge firmly and try to print.
