Digital BW, The Print

The yellow ink position should be the lightest ink, and therefore 
faint, but easily discernible.  Also, you should not use the "head 
clean" cycle to purge old ink. It is better to print images to clear 
put the old ink. I belive inkjetmall.com has such an image for 
download, as do inksupply.com and mediastreet.com.

Good luck.
