My glass is cracked. How can I replace it?
No glass listed as available parts
Your best bet is either buy another or buy a non working one off Ebay to swap the glass out but there are no manuals so you'd be on your own to open it up unless someone has a video on Youtube. If buying a dead printer be sure to ask the seller first if the glass is in good shape and not broken.
There's a few listings in the US at least, depends where you're from, they run about $33-35 US with shipping. Usually they get listed as No Returns so it's a bit of a gamble but about the only source for parts
