Hello! My fanstastic HP 3500 LaserJet stoped (just like that!?) printing cyan. COMPLETLY! It wored fine and then, simply no cyan (OEM HP toner - 80%). Printer dosen't show any errors, nothing. I got new toner (OEM HP) printer printed few pages, I did calibration and NO CYAN.
PLEASE help me, my printer is "full of toner" and I can't print 
.
PS. All other color are great, no issue.
PS2. Here is my post with attached test print for each tonner:http://h30434.www3.hp.com/t5/Printing-Issues-Troubleshooting/HP-3500-LaserJet-cyan-missing/m-p/3133459#M63337
