Kyocera FS-C8520mfp will not copy or print in color

[ZeusGT]

Hey guys,

I have a customer with a Kyocera FS-C8520mfp that will not copy or print in color. The customer has replaced the transfer belt and toners, but it still will not copy in color. When you do a color registration test print, the print will print out in black and white only. When you print the supplies page, the color bars print out in black and white only. The error codes are 7620 and 7612 which is a cyan ID sensor error.

Ive tried making sure full color is default and selected. I've tried resetting back to factory defaults. I've tried everything that I know of except to replace the PWB.

Can an you guys please help with which way I should go with this? Oh and firmware is system 11.

Try upgrading the FW. On versions earlier than v.06.12.0010 , when a color toner ran out the MFP switched to BW Printing but did not switch back to full color when the toner was replaced.

service mode number u089 , printing belt colours should show if the engine and drum/dev is functioning ok.

take all the toner out, turn the machine off (complete off). reboot, after it says ready reinsert the toners. sometimes it likes to do this.
