I have the following situation then printing on my DC252 with Fiery stand alone controller.
Copies BW and CLR - OK
all inner pages
procon ON/OFF, erreurs, maxsetup, printing patterns - OK
prints BW- OK
All color prints (in all formats and applications) come out with Yellow backgrond (apprx 30 pcs) on all printable area.
Fiery calibration gives OK massage even on the pattern pages with yellow background.
Modifiing color profiles, rendering intents, NVM initialisation, and restoring factory values on FIery and printer did not worked out.
This is my back up machine which was immobilised for one year and I just restored the Fiery with factory CDs
Thank you everyone in advance
Try to reseat cables between the machine and Fiery and all connections in Fiery, and VSEL PWB in ESS.
