Electronic counterfeiters are often just ghost shifts at contract manufacturers. If a single company is handling the injection molding, PCB, and assembly, they can run a secret shift that makes units for them to sell themselves. Even if they can&amp;#x27;t get ahold of all the surplus parts they need, they can design their own.&lt;p&gt;Since the firmware is different,  HP could have also outsourced production maintenance too (i.e. updating firmware if a chip reaches end of life and needs to be replaced with something that&amp;#x27;s not exactly compatible) which isn&amp;#x27;t unheard of for legacy products that no one wants to deal with.</text></comment>
