SOURCE: when printing on my HP
The HP88 printhead can dry out and cause clogging in the black part of the K/Y (black/yellow) printhead.
This has been a major problem for a few client schools of mine and for me in my attic space where air conditioning and/or hot dry air causes clogging.
You may want to consider purchasing a new printhead and an alternative black ink supplier (non HP) that uses Dyebase ink instead of pigment as this doesn't clog in the same conditions.
However, please note that if you do this it means you may lose your warranty (certainly on the printhead) and the printout won't be as clear for text as the black ink can "bleed" slightly into other colours. It has however solve the problem of clogging in one school that went through 5 printheads in two terms/semesters until we switched.
