Question about HP PSC 750 All-In-One InkJet Printer
This seems to be a common big problem with the HP 750. What is the cause of this, does something get dull or faided in the scanner?
The failure is probably due to a bad signal coming from the "eye" that controls the warming up. The "eye" has to catch a reflection from a small mirror which is probably dirty and reflects nothing at all ! So you always get continuously "warming up" .....
The mirrorl is somewhere very near the moving lamp.
I managed to repair my psc in cleaning that mirror. But ... be very carefull; it is not easy to open the printer and when you disconnect the command ribbon, write down how you did it !
I wish everyone patience, good luck and .... success !
