Test pages from HP 7612 have problems and don't know how to fix or if can be fixed

My printer was printing fine and then started to print streaks of color across photos only.  When the yellow cartridge ran out, I replaced it, but it ran out of ink much more quickly than it had in the past.  I cleaned the print head several times.  The test page kept coming out wonky, as did the printer report (see photos below).  I tried changing out the cyan cartridge, since cyan wasn't printing, but that didn't change anything.  I did a hard reset, pulled out the cartridges one by one and replaced them one by one.  I've run the HP print doctor.  The printer is probably at least seven years old.  I don't know if it is worth trying to fix it, or if it's time to get a new printer.

i think 7 years is a good time that the printer has served you. my Canon laser printer is at its 6th year and its network connectivity failed. i now use it using a usb cable instead.  do u use original cartridges or oem ones from those aftermarket cartridge providers?
