Hi Narendra,
This is really difficult to answer without being on site!
All I can think of is perhaps you have some piece of paper stuck inside.
If you had some paper stuck before, and you had to pull it out causing a piece to rip off try putting the bits back together again on the desk, if you can't find them all then that's the bit still stuck inside you need to look out for inside.
If in doubt you will need to get your local engineer to have a look inside.
Good Luck.

This is general error of the printer. When you have to change the new mother board you should be initialized it then it can be ready mode. When you try to initialization you need printer printer adjustment program. You can batter find out from google & write down EPSON Stylus R230 Printer Adjustment program or ink reseat program.

If paper jams every time, just open printer cover, pull out toner cartridge and you see paper feed roller it is rubber, just clean roller with alcohol and cloth.

I hope this help!

check the waste toner (it's on the left side of drum unit when you open the front cover) cartridge or paper jam if blinking!

restart than on
