Even assuming you dedicate such time to it, very often the hardware itself is pretty poor and fails you. I recently had to basically take apart an (admittedly cheap) HP inkjet printer in order to reposition part of a hall-effect switch that helped it detect a paper jam - it was detecting a jam continuously because of it. And because the same printer hadn't been used in 5 months, I also had to clean the clogged head with a syringe afterwards.
