To get the 77% of iron, I had a smoothie with 3 bananas, 3 dates, 1.5 cups of juiced oranges and 1 nectarine and I snacked on 120g of blueberries (one punnet), 73g of pistachios and an apple =) Just shows how easy it is to get iron =)
As for the low iron, heres a link you might like to look at:
http://www.vrg.org/nutrition/iron.htm it has a list of foods that are high in iron.
The pistachios I had (according to the cronometer) made up 36% of that 77% of iron, so maybe snack on a handful of pistachios and some apricots every now and then. I usually add somes greens to my smoothies too which really help with iron, ie:
About 70g of bok choy, celery, endive and rocket (arugula, roquette, not sure what the right name is), 2 bananas, 3 dates and one cup of coconut water gave me around 50% of my iron requirments, it definitly wasnt the best tasting smoothie, but it was stll enjoyable =P
I used to have a problem with low iron when I was younger, as well as my sister and she eats meat everyday! So it's not because of your vegan diet, it's just our silly female bodies, i'm not sure about my sister but my last blood test showed that my iron levels were perfect =) Unlike 5 or 6 years ago when I was told I needed suppliments, which I never took, naughty me, I HATE pills lol.
This link is good too! It tells you how to increase your iron absorption and what foods can interefere with the iron absorption:

It says to get the most out of your iron supplements they are best taken on an empty stomich with a glass of orange juice =)
The cronometer has been awesome, I wouldn't of though I could get so much iron just from my morning smoothies !
