I am service engineer in a complex, i am facing a peculiar problem in color laserjet 3600, when we switch on and give a color print command from system it prints black and white print. when i reseat toner cartridges, transferbelt, formatter etc it gives a couple of color prints then its back to its original path starts printing black and white. This is a problem which no one could solve till now in spite of best efforts and suggestions after cleaning developer solenoids and cleaning inside the problem is unsolved.
Can any one suggest the possible solutions for this black and white printing problem. I heard the same problem from my friends who use the same 3600 color laser, when I reset the settings it prints in few color prints and goes back to black and white. It is strange to see this happens in all the printers I have, and my friends who use the same printer also have the same trouble. Please suggest me the possible solution , I will be grateful for any suggestion or guidance to clear this problem. This is becoming a big issue in my life.
