HP Officejet Pro L7580 prints some lines but does not print others

If an alignment does not work and if the cartridges are known good, then something has failed or become misaligned inside.

I had an HP 8500 printer that did something similar and it was the print heads. They were expensive to replace so I replaced it with an HP 8610 which is still working fine

update: i have run clean print heads about 20 times, and more of the text starts to be printed.  what does that say?

Many cleanings can improve printing, but you say (as I interpreted the above) that printing is still substandard.

So something must be wrong inside the printer.

ugh.  is this something that I can fix - i.e. clean - or do i have to get someone else to do it.... and, if that is the case, it is better that i purchase a new printer vice get it repaired?

yeah.  i have an hp officejet pro L7580.  i think is must be 5 plus years old.  probably time to replace.  thanks for the help!

Thanks for the update. Printers may go for 5 years or more, but at that age, repairs are normally not economical. Good luck with a new printer.

thanks for the help!!!!  I am old enough to remember electronics that would last for 20 years!!!  repairs were inexpensive!  now, it seems electronics are now throw away... i bought a receiver for my stereo in 1985.  It finally gave up the ghost in 2007.  one 80.00 repair in 22 years.  Of course it did not have all the new bells and whistles of today, and would no longer be compatible.

Yes. It depends on the product and the cost of a new replacement.

I have an HP606B signal generator in the basement that hails from the mid-1980's and it still works very well. Some electronics stuff can last for a very long time.
