Pixma mg3150 ink there but showing as empty

All Epson printers (well, the ink ones) have a small utility built-in called the STATUS MONITOR. If you click on the MAINTENANCE tabbed page in the Properties, you can start this just by clicking on the item. It will show the ink levels. Normally, this status monitor should start up whenever you print - with an option to show the ink levels, as they do not auto appear when printing, compared to the option shown above. Note that the monitor does NOT actually shown the real ink levels as the chips on the cartridges and the internal electronics within the printer simply work on the number of prints made - so often when showing empty - there will in fact be ink left unused inside the cartridges. For this reason alone, worth your while getting some refillable cartridges and bulk ink (normally in 100ml bottles - so you would get equivalent about 10+ refills and save lots of hard earned dosh!) but you would also need an inexpensive chip resetter. My advice is get the refillables with ink (most compatible inks are as good as - some better - than Epson's own expensive original cartridge inks) and when one cartridge shows requires replacing, you remove all the cartridges, fill them all, reset the chips and replace - that way you show all as full and on ly have one cleaning cycle - thus also saving lots of ink normally wasted when replacing one cartridge - each requiring a cleaning cycle and loss of other inks. I have no idea where in the World you live so cannot recommend a supplier - just use ebay.com or amazon.com to find suitable suppliers convenient to yourself.

Please check the cartridges.Re install the cartridges properly and try.
if ink is dried refill the ink.some times will happen to new printers also.if waranty is there cary to nearest service point.

try tthis
Press and hold the Stop/Reset button until the error clears.
If your printer doesn't have a Stop/Resume button, use the Cancel button. Hold the button - until the Alarm LED stops flashing,
or until the error message disappears. This takes 6-7 seconds.
Note: You will have to repeat the whole process with every cartridge that indicates empty (in the ink monitor).
Good Luck
Thanks

the ink tank could be empty or wrongly installed. Try a new ink tank or re-install the one you have.

This is because the ink cartridges has a memory chip.It monitor ink levels.Press and hold the resume button for 5 seconds.This operation releases the function for detecting the remaining ink level of the above ink.The printer shows empty cartridges but it will printing.

Show empty or not recognized (cross sign)? Check connector at chip and at head carriage. Do replacement procedure form status monitor (how to..). Do replacement ink tank one by one with cyan ink first.

I replaced CLI-8B cartridge for some reason, problem is corrected. I still have print quality problem but  at last now I can use my printer.

If the ink light is on steady red, that means the black or color ink cartridge is nearly empty. Obtain a replacement black or color ink cartridge. To know which cartridge is out of ink, check the ink levels using EPSON Status Monitor 3 (Windows) or EPSON Status Monitor (Macintosh). If you just replaced the cartridges before you got the error light, that means that the replacement cartridge is not recognized by your printer. Please reseat cartridges. Then turn the printer on and off. The cartridges maybe bad also.
If the paper light is on steady red, try to reload 10-20 sheets of regular paper into your printer. When printing on CD/DVD, CD/DVD tray is not inserted in the printer. Insert the CD/DVD tray in the printer and press the paper button.Could also be that the printer has loaded more than one sheet of paper at a time. Load paper in the sheet feeder, and then press the paper button to resume printing. If the CD/DVD guide is open, close the CD/DVD guide, load paper and then press the paper button.

Fill up the cartridge as printer software does not always monitor right ink level even its happens to me many times but fact is cartridge is empty fill it up thats it

I had removed and reinstalled the empty 3e cartridge. Sorry for the Confusion. I hadn't put a new 3e cartrige in until today. Them I ran " deep clean" twice. The printer works fine. I still don't understand why the printer wouldn't print color, when I was had set the printer to print in color when my 3e cartridge was empty and all colors including the 6 black showed full.
