Electrical – Problems with toner transfer method

pcb

I am trying to make a pcb using the toner transfer method. The problem I have is that the toner does not transfer completely so i cannot proceed to etch it.

I am using glossy paper, a laser printer, and I have polished and cleaned the pcb before ironing it.

I add some pictures to see if anyone cal help me out.

There are parts that the toner doesent stick at all:

If you heat the toner it will melt. Take the printed paper and put it on an iron for clothes, see if it melts. There is another method, use acetone mixed with isopropyl alcohol. It requires no heating. But the acetone must be pure, not mixed with water. It is very important to heat and press it uniformly(heat), or press it uniformly(acetone method). Use warm water to remove the paper. Let the water completely soak the paper.
