Blue screen HP Designjet T520 and T120 solution

If your HP Designjet T520 or T120 shows a blue screen and an error code immediately after turning on the plotter, then the encrypted chip on the motherboard is defect.
This encrypted chip is not supplied separately by HP, but you can purchase it separately with us. There are two solutions for the problem.

1. Replacing the motherboard

Replacement is relatively easy to do yourself. However, some cables have to be disconnected. The disadvantage of this option is the high price of the motherboard. After replacing the motherboard the blue screen will disappear and the printer will work perfectly once again.

2. Replacing the encrypted chip on the motherboard.

This is the easiest and cheapest solution. No cables would need to be disconnected. Only the encrypted chip will be replaced. The encrypted chip is located on the motherboard with a USB connection. Remove the old one and click the new encrypted chip in its position.
Advantage: It is easy to replace the chip yourself and it is three times cheaper.
