Re: AC-Adapter for Battery operated device

I have also assumed that the batteries are removed when he tries the external power supply. They could become a pretty decent load themselves. Getting pos and neg backwards would be the most obvious cause but he has already said he did not do it. Without new evidence, we are at a dead end. That wou...

Re: AC-Adapter for Battery operated device

If your power pack drops to 0 volts, you have a short circuit or a extreme load. If the printer works with batteries, and if this all happens when you connect a power supply, there is something wrong or different. PERIOD If a device works fine with batteries, logically, it is in working condition a...

Re: AC-Adapter for Battery operated device

The battery compartment only has 2 wires. Positive and negative. I believe if there was a problem with the intermediate battery connections the printer would not work properly when in use. The DC power board only had 2 wires that came out of it. DC power supply's voltage drops to 0 when connected to...

Re: AC-Adapter for Battery operated device

Thanks, Haklesup. The printer gets used at least once a week, the power button is a momentary/soft switch so I’m sure it is using a very small amount of power at all times and the batteries were installed a few months ago. So the batteries last a long time. When I got the printer, it already had a t...

Re: AC-Adapter for Battery operated device

My frustration comes from the fact that you’re not reading everything I typed, you keep referring to the useless manual and you look for what might be in between the lines rather than focusing on the lines. Yes, it was necessary to modify the wiring on the jack. The special circuit Brother installed...

Re: AC-Adapter for Battery operated device

Methinks the printer has been modified. Without accurate information remote help is unlikely to be a success! Yes, it has been modified and the only mod is the wiring of the DC jack. The only way you can help is if you know how to make this device see the DC power supply as a battery. Even though D...

Re: AC-Adapter for Battery operated device

most common causes would be 1. The jack is not intended to power the printer, only to charge the batteries. This is common with some shavers for example, plug it an and it still runs slow until the batteries charge a little more. 2. in a prior attempt to select a power adapter, you may have tried o...

Re: AC-Adapter for Battery operated device

I thought when I had tested it a few months ago the voltage did not drop but I just tried to test it now and the power supply detects a short and shuts off. Printer still operates fine on batteries.

Re: AC-Adapter for Battery operated device

Besides, if there is a jack, it could be because I added one This model has a DC 9.5V jack on the right side! it had a separate circuit board for 12V DC power that fed directly in to the mainboard. Why 12V when the AD60-AD24 Brother adapter is 9.5V? Doesn't matter. The DC power circuit board is not...

Re: AC-Adapter for Battery operated device

Lenp, I wouldn’t say that it doesn’t work with rechargeable batteries if I hadn’t tried it with fully charged batteries. The typical rechargeable is only 1.2V so that may be a reason why they won’t work. This unit is a Brother P-Touch 2600. It had a separate circuit board for 12V DC power that fed d...

Re: AC-Adapter for Battery operated device

Jack is fine because there is voltage at the circuit board when the batteries are not there.

Re: AC-Adapter for Battery operated device

Oh yes, I am using 12V DC and one of them had a 4A output. Polarity checked to be correct. The batteries are all in series and checked wiring (1 wire at each end of the series). Also, if the batteries and 12DC power is connected the printer turns on and i'm pretty sure it only uses the batteries for...

AC-Adapter for Battery operated device

Hi, I've been researching this and cannot find any info on this.

I have a label printer that can only work with batteries (eight 1.5V batteries and will not take rechargeables). I have tried various 12V AC-adapters (with a steady 12V output) without any success.

How can I make this work?

I'm glad too dude! I reopened the box to make sure its chassis is grounded properly. I took pics but can you post pics here?
