I have a problem with a color laser printer HP2600
After printing about 10 to 15 perfect color pages (some times after 3)
but generaly first pages that came out are perfect
it start to print only with black cartridge - no traces of CMY
Printers demo, status and supplies pages are ok
Optics are cleaned and firmware upgraded
Cartridges are original
Any idea???
