The Epson LQ630 printer used to be good and suddenly stopped printing, please ask what the problem i

1.See if the printing cable is loose, it's best to unplug both ends and plug it in, remember to power off the operation, otherwise it will burn the motherboard. 2.

Delete the printer from the printer and reinstall the driver. The specific method is: start - set up - printer and fax - right-click your printer - delete, and then go to the online ** driver, install it, you will not be able to ask colleagues for help.

3.It may be a temporary problem, after doing the first item, turn off the printer and computer, and turn on the machine again. Turn on the printer first, then the computer.

1. If the printer is not powered on, first check whether the power cord is in good contact with the power strip, if the power cord and plug board have been replaced, but the problem still cannot be solved, it means that the fault is not caused by the power cord and the power strip.

2. Check the power strip of the printer, if there is no obvious short circuit, overheating and damaged components, and the safety of the power strip is powered on normally, you can rule out the problem of the printer power strip.

3. If the printer was originally used normally, the print head was replaced due to serious needle breakage, but the printer was not powered on after the replacement and suddenly stopped printing once.

Then it may be because there is a problem with the print head that causes a failure without power, after removing the print head, test whether the printer is powered on normally, replace the print head again, if the power is normal, and there is no power on the fault after printing, it is not the cause of the print head, but the abnormality of the printer motherboard, and the printer can be restored to normal after replacing the printer motherboard.

My lq630 has this situation, the test paper can not be typed, but also jammed, in fact, the problem is very simple, you open the front panel of the printer is transparent to take a cover, there is a copper-colored iron rod behind the needle box, the problem is here, there is dust on the top for a long time, plus this iron rod has oil on the factory when it leaves the factory, and the paper will be jammed after more dust, you use a good paper towel to slowly wipe it clean from left to right, and brush some oil on the top with a cotton swab to find a little transformer oil, Be careful not to get too much, and then put it on and try.
