Brother Mobile Printer PJ-763. I purchased this used some time ago and used it for a while. It seemed to work fine back then, but I haven't used it for about a year and have been storing it. I tried it again recently, but it doesn't seem to turn on. When I connect the AC adapter, the orange lamp lights up, but I couldn't confirm any further operation. I hope someone with more knowledge can take a look at it. This listing is for the main unit and the battery only. The AC adapter and USB cable (mini-B type) are not included. I used a general-purpose 15V adapter before, so please use that as a reference. Please understand that this is a junk item before purchasing.
