Gen2 raising head current

[proline111]

Hello,
I was just wondering how can I raise printer head current.
Anyone have any experience?
Which sw do I need to modify original firmware?

Are there any adjustable potentiometer dials on the main bill head's circuit board?
If so, try turning it like maybe a quarter turn or so, with a small jeweler's screwdriver, to see if you get any difference in printing.
Make a note or marking of where the dial is positioned at with a fine point marker, before turning.
It's too bad I don't have a good diagram or schematics of that board in there to help ya.

You may have to do a little disassembling to remove the cover to get at the circuit board first.
There will be 4 screws underneath the plastic paper tray label in each corner.
Be careful with the small ribbon cable for the LEDs and microswitches.

Also, make sure you use fairly new TITO coupon ticket paper, to rule that out, as part of the problem.
