not recognize the cyan in C-6500 please Emergency!!!

[HORSE]

Have you checked that the Cyan 1st Transfer roller has not fallen out of its holder in the Transfer Belt?

Also you could try to Panic stop the machine to see any image has been formed on the drum. Start with the simple stuff and work your way back.

somebody have athoer idea

[gang1110]

we check already those connoctors in the right side were is the image board and hdd its ok

[mrwho]

when we run proccesing we get sc28-03

Of course that's to happen if one of the colors isn't developed. You can also check all the connectors on the right side of the machine (the four white and blue connectors to the right of the paralel and network ports).

Are you getting any error codes?

[mrwho]

Check for anything blocking the laser path (and if the laser isn't somehow misalligned). Also check the cyan drum ground - without ground, the drum is prone to make blank copies.

[gang1110]

yes

[mrwho]

When you say you print in test mode, you're refering the engine test mode and not the controller, correct?
