Re: Empty Ink message

Try this 1# :

If you still have trouble:
unplug machine from power. Open cover and take all carts out of position. Plug machine to power again by connecting it to the wall socket. Wait until machine has done start up. When finished power on machine (if it has shut down first). Machine demands carts. Place each demanded cart into position and make sure it is secured. Answer lcd display questions. Close cover. Machine will run a cleaning cycle and come up stand-by.

If you still have trouble after that procedure, use another ORIGINAL cart. (Most brother printer  trouble is because of diffrent construction of generic ink carts and due to wrong ink).

And if there still is trouble have a look at the led control circuit board built in the cart holder it should look this:

I replaced an ink cartridge because the printer stopped working and showed a message that the old cartridge is empty. However after putting the new one in but the printer still refuses to work and shows...

maybe the cartridge is wrong, release it and clean the electrical contacts, put them again one by one, if notting happen, try this
Solution As the printer operates, it moves ink from the ink cartridges into a printhead reservoir. The printer does not deliver a message when an ink cartridge goes empty, because it still has ink in the reservoir. The printer continues printing until the ink level in the reservoir falls to a first trigger point - then a message appears advising the printer owner to Replace Cartridges Soon . At this point, other cartridges that are empty but have not reached the trigger point are also mentioned in the message, to save trips to the retailer. After the first trigger point, the printer can continue printing until ink levels in the reservoir reach a second trigger point. At the second trigger point there is only enough ink left to perform vital servicing tasks, and a new message appears, saying Ink Cartridges Empty . The options offered depend on the usable inks remaining. If no options are offered, the cartridges indicated must be replaced before printing can continue. The Ink Cartridges Empty options are described in the table below: Ink colors out Option Print mode possible All Cancel None Black


Cyan, Magenta, or Yellow (any or all) Black only Continue with other colors Cyan/Magenta/Yellow mode (composite black)

Text and photo quality will differ from those printed when all colors are available Light Cyan or Light Magenta (either or both) Cyan, Magenta, or Yellow (any or all)

(Black still available) Print with black ink only Grayscale

Ive replaced black ink cart but it doesnt work,still the message check ink u163 on th LCD.thank you

Either the new ink is a generic cartridge and not reset properly, or one of the other inks is empty. Your display should tell you which ink is empty. U163 just says that one of the inks is empty.

Epson CX3900 says all cartridges empty but not true

Did you use Epson Genuine Cartridges?

ALL…. Epson & Brother Requires Genuine Epson Cartridges. !!!!!!!!

Also go thru the utility to change cartridges. This will make the chip know that you have all new cartridges and will move the ink station in place.

In Purchasing Epson's CX 5400, CX4600, & CX7400 and more, I found out that Epson does not like Generic Printer Cartridges. I also Purchased a Brother. That also does not like Generic Print Cartridges. Color that should be Yellow, will turn out Green, Blue Brown, etc.

These printers have a CHIP that will detect if it is Generic or Genuine. When they see it’s Generic Cartridges, it will print lines thru the words, stripes across the picture and also do a mix match with the colors. It also will not let you print anything, if only one of the cartridges is empty.

I wanted to print only Black, and would not let me, because I did not have any ink in one of my cyan cartridges. Go figure.

That's what these Companies do., so they can keep selling the ink cartridges. Some Printers, are able to use Generic, and some are refillable. Some you can refill them up yourself and I heard, quite MESSY.

So I learned, thru trial and error, that you must use the ORIGINAL Genuine Cartridges for these PRINTERS. Some people say some models work fine compatible, but not mine.......

I had to replace the printer, but Epson, Lexmark & Brothers are always on sale. My Brother & Epson cost me $50.00 with Rebate. .

This is the only advice I can give you. If you find this helpful, pls rate me.

Thanks and Good Luck :0)

Printer thinks cartridges empty

Unplug your printer from the computer and then the power supply. Remove the inks from the printer. Plug the printer back into the computer first then connect the power supply. Install the inks "very slowly" one by one and then check the levels, they should now read full. Thank you, Dana

Changed yellow ink to new cartridge. Printer won't recognize.

I contacted the Brother site, the support function there. Pursuant to what I found there, I unplugged the printer for ten seconds and replugged. The message display then told me that cyan was empty, and that magenta was near empty.

I installed a new cartridge in place of the empty cyan, and that fixed it.

Printer cannot detect new yellow ink, the near empty message on

The Ink sensor sounds like it needs to be replaced. This happens from time to time.
