LQ-2180 printer is Continues blinking front panel lights.

An Epson LQ-2180 is an old dot matrix printer, it cannot be programmed like newer network printers. All it has is a panel in front where you can select a font, the pitch of the font and paper type. There is nothing to reset.

There is a problem in panel
u need to check panel cable if it is connected properly 
if the prob. doesn't be ended then u need to use another panel

if u use up tractor use down tractor or inverse the operation 
coz your problem is in paper sensor in up or down printing

Your ink absorber is full but it just a counter. you can reset it with reseter software. you can download the software here

Please read through these instructions first and then follow the steps below:

1. Please power the printer OFF.
2. Remove the printer cable from the back of the printer and remove all the paper as well.
3. Hold down the "FONT" and "TEAR OFF" buttons and turn the printer on.
4. Continue holding the "FONT" and "TEAR OFF" buttons down for five (5) seconds and then release both at the same time.
5. Power the printer OFF.
6. Reconnect the printer cable.
7. Reinstall paper and ensure the thickness selector is in the correct position and that the path selector is also correct.
If the situation persists, remove the ribbon and paper and slide the print head back and forth so that it makes contact on both sides forcefully enough to make a loud noise. Reload the ribbon and the paper and try your test again.
