Prints like it is running out of ink, but it is a new cartridge. Some sentences are printing, others are blank, or partially printing.Followed instructions to align and clean nozzles. Doesn't help.

If you have lots of flashing error lights or electrical problems then it is likely to be electrical.

However, if like most... and your
printer has just been left unused for some time? You probably have an ink clog on the cyan and magenta. Or possibly a faulty cartridge.

Provided it worked OK before a period of non-use? Then you just need to use a Magic Inkjet Flush PRINT HEAD CLEANING KIT to unclog the tiny jets. (available from https://magicinkjetflush.com)
It usually works a treat on those!

Magic is ideal for unclogging the tiny jets on any Canon, Epson HP and great for removing those horrible white lines which usually appear in 
prints when dried ink clogs several jets...

So if yours appears to be a clog? all you should need to do is to use the Magic Inkjet Flush Kit to soak the print head and you should be printing again like 
new.
