When starting my lq printer beep sound is comming and pause light is showing

I have epson lq-2180 printer with the following problem: Paper out & pause indicator is continously on when I try to print. The paper is rolling when I push pause button.

It is a logic card problem. so pls checked it from service center.

Printer can't have a password, maybe a network password you are referring to? I double checked in the manual for this printer and there is no way to set a password on the printer...

my problem is how to install epson lq680 in windows xp,before i installed but font not correct,i have not get a english word
please give me solution about this problem

change the font settings.press and hold the pause button then a beep sound will produce after that change the font settings.

problem with detector cable or detector sensor

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

plz check the ink status and check is there any paper jam

Probably needs a good cleaning - with a vaccuum and some compressed air.

Dot matrix (impact) printers usually have a couple of optical sensors - disks with holes in them - to let the printer know where the head is, how fast it's moving, if it jams, etc.

If there is too much dust, dirt, or bits of paper interfering with the beam of light passing through the rotating disks, most printers will stop and indicate some sort of error, rather than force the motor - which may damage the plastic teeth on the gears.
