I have changed the ink cartridges but the printer is still printing very lightly

You would require to change the tri color ink because its and ink jet so you would require both the cartridges in to make it work properly

Using the printer's control panel In some circumstances, you may need to replace an ink cartridge before it is empty.
If the ink out light is flashing or is on, replace the empty ink cartridge as described in Replacing an Empty Ink Cartridge.
To replace an ink cartridge before the ink out light flashes or the Status Monitor notifies you that the cartridge is empty, follow the instructions in this section.
Caution: Do not remove the cartridge from the printer until you are ready to replace it with the other one.
Make sure that the printer is on. The power light should be on, but not flashing.
Lower the output tray, then open the printer cover.
Press the ink button. The print head will move to the ink cartridge replacement position, and the power light will begin to flash.
Note: Do not press the ink button over three seconds. Otherwise the printer starts cleaning the print head.

Replace Ink Cartridges
Your Epson Stylus NX110 Series and its software will let you know when an ink cartridge is low or expended.
If ink is low, the ink light flashes. You can continue printing until a cartridge needs replacement.
If a cartridge is expended, the ink light stays on. You must replace the cartridge to be able to print.

Warning:
Keep ink cartridges out of the reach of children and do not drink the ink.
Note:
If you need to change a cartridge before it or any other cartridges are low or expended, run the Ink Cartridge Replacement utility.

You cannot print or copy when an ink cartridge is expended even if the other cartridges are not expended. Replace any expended cartridges before printing or copying.

Leave your old cartridges in the Epson Stylus NX110 Series until you are ready to replace them to prevent the print head nozzles from drying out.
When an installed ink cartridge is more than six months old, you may need to replace it if your printouts do not look their best, even after cleaning and aligning the print head.
Follow the instructions in these sections to check and replace your ink cartridges:
Check Cartridge Status
Purchase Epson Cartridges
Replace Cartridges Using a Printer Software Utility
Remove and Install Cartridges

pls rate me. Thanks and Good Luck...

One or both print cartridges are defective.Look under the "check ink" what message come.If it's BLK change black cartridge, if it's CLR change the color cartridge.If BLK and CLR change both cartridges.

It was a problem with the black ink cartridge. I changed it and the printer is working fine.

Some times you need to find the epson tools that comes on the CD to reset the printer. If you have upgraded the computer you may need to update your drivers at the epson sight.
Once you have opened the epson tools try cleaning the print heads.
then it should reset the inking system to default and read the new cartridges. If this doesn't work try shutting down the printer and removing the ink cartridges, restart the printer and allow it to find no cartridges the go through the process of reloading the ink cartridges again and cycle the printer.

If this doesn't work you may need to try and find a cleaning cartridge for the print heads. Since the printers always check to see if ink is getting to the print heads if there is no ink flow it will always come up like there are no ink cartridges installed.

Hope this helps


Make sure paper is in properly they can be very picky about that.
Try turning it off wait three minutes and turn back on.
Then
Push Paper refill button Wait for cycle and see if paper light stays off if so...
Push the ink button

Perform the following procedure:
n Press the ink cartridge replacement button until the print head has moved to the change cartridge position
n Lift the lid that holds the cartridge (do NOT remove cartridge) and press down immediately. Then press the ink cartridge replacement button and allow the cartridge to charge the print head. Do NOT switch the printer off until the printer has finished charging.

If red light again you must download resetter software from internet to reset your printer.

do you print CD or plain paper, red light is mean jamed paper or change cartridge. Open the top door >press drop ink symbol> look at printer head show on ink ink tray.

Light/faint prints usually are a result from clogged ink or air bubbles between the cartridge and print head (thus changing cartridge wont fix problem). Try printing the test page print from the machine (Ink Management -> set/ok twice). Answer the question(s) in the display and repeat this up to five times. The colors should be improved after 1-3 test prints usually.

you must change your printer settings to the default settings.
