Hp psc 1500 constnatly blinks check printer...

Question

t take the print job. However, when the stop/cancel and the color button are pushed simultaneously it prints well and also takes the message of print test page properly. Otherwise the test print cartridge keeps on blinking and precludes the printer from working. I have been refilling ink in the cartridges from time to time and it seems to be working well. when contacted the toll service service they seem to pursading the cartridge change. Bhawnani
