Troubleshooting Epson L210 printers common problems

I just want to share here some of things I want to remember when troubleshooting this printer "Epson L210".. Some of which are very common...

1. First, sometimes the printer does not print or no ink is printed when going through the printer even when the ink tank is full.

- Of course, common things we really check when the printer is not printing is the ink, but what if it is full? most often the common problem is that, there is this switch on the tank itself, where you can turn it like "on" or "off". Turning it down, would mean the ink would be turned "off" (usually done if the printer is being transported for protection / security purposes). And turning it up, would mean the ink is "OK" for printing. Sometimes, we tend to forget switching this, so when it prints, the printer at first can print, then suddenly after 2 or 3 pages, it doesn't print at all. Then that becomes a problem and we panic, and check the ink. But forget this switch.

2. When the ink notifier blinks (see picture belows):

- one reason why this blinks is that the ink itself maybe really needs to be refilled. But sometimes, this still blinks even when refilled... one reason maybe because the ink cartridge is "re-charging".... from searches as well, they say this happens within at most 20 minutes.... In other words one have to wait for 20 minutes before it goes back to normal.....

- but this is not always the case... sometimes the ink blinking may mean another reason, and not because it is charging or it has no more ink... It's possible (specially when the ink and the paper are both blinking), it may mean the printer may need to be "reset"

And how does one reset the printer?
1. put off the printer
2. try taking off the power cord of the printer, then press the "on" of the printer (sometimes power is stored inside the printer's power supply). This process makes sure the printer is really off and has no power.
3. put back the power cord
4. now press and hold the "stop/cancel/reset button"
5. while pressing the "stop button" turn the printer on. and while still holding the "stop/cancel" button, wait for ... say 10 seconds... then release it...
that's how it is printer reset.

IF this process does not solve the problem, here is an instruction I also searched for and followed.. and it really worked. don't know why, but it works somehow.. may not be for other cases. But here it is:

"press and hold resume/stop button for 5 seconds then release the button, hold and press resume/stop button again for about 3 seconds then release the button and finally press again resume/stop button just once then restart the printer. after restart the printer it should be normal again. sorry for bad english."

These are just the common problems I've experienced with EPSON L210 even with L110. hope this helps others..
