the problem needs solved in code you're not showing. you're adding header @ position x = 34, y = 803. assume you're creating document object this:

document document = new document(); 

this means you're creating document a4 pages , margins of 36 user units (half inch).

a4 means height of document 842. if substract margin, have y = 806 top margin. you're adding @ position 803, need larger top margin. see constructor of document class more info.

for instance:

document document = new document(pagesize.a4, 36, 36, 72, 36);
