Re: print problem

The yellow one first:

For the BK one:
make sure that all carts are placed well and are secured.
Press menu then start mono (blue button) then fourtimes arrow-up (tel-index). machine will be in maintenance mode. press 7 then 6 then 4 then start mono. machine will initialize the carts and refresh the ink within the tubes and the ph. It does some cleaning too. Leave maintenance afterwards by pressing 9 then 9. Run a quality test print by pressing ink etc.

If you still have trouble with bk this part of the ph is clogged due to generic ink (pigments).
BTW the nozzles have a micro filter infront. generic ink will clogg the filter. Use only dye-ink for all brother printers!!

Best resolutions will be achieved with original ink wich cleans the ph, too!

Printer keeps telling me that the yellow cart is empty and I have put a new one in

Are you positive it says the yellow cart is empty? Because that brother printer is designed to say that a cartridge is empty whenever ANY of the color cartridges are empty. Usually it doesn't tell you which one is really empty either. So even if you replaced the yellow cartridge and say, the black cartridge is empty, it still won't let you print until you replace that empty black cartridge, nor will you know which of the cartridges is empty unless you pull them out of the printer and manually check the ink levels.

Its pretty much a guessing game with those old brother ink printers.

Hope this helps :)

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

After repalcing the black ink cartridge on the printer the printer doesn't recognize that it's been replaced and shows that it is still empty. It will print very light in black. What is the problem

make sure that the protective tape has been removed from the cart, and that the cart has no debris on it.Then, run your cart cleaning/testing program. If that still fails, return the cart as a defective item for an exchange.

Cartridge not recognized

Yes. Unplug machine from power. Wait 5 minutes. open scanner and take all the carts out. close scanner. plug machine to power again. machine will do the start up cleaning. Machine demands carts. insert NEW carts and give the answer in case you are asked by machine.

Do only change the carts when machine stopps for EMPTY cart. As long as it shows Nearly Empty everything is alright.

The machine has a drop counter and counts the ink drops down to zero when the flag is raised within the (nearly) empty carts. In case you take them out at that moment and reinsert again the ink inside will splash and raise the flag again. Control logic will be in trouble....

Brother MFC-640CW Replaced Black catridge becomes empty

Compatible carts do make a lot of trouble. One point is the draining! The ink has flown into the cart assy and beyond that to the bottom of the printer. As long as you can print without problems you dont have to do anything. If the test pages wont show the correct color you have to open the printer and to clean the assy and the bottom.

Do use original ink carts though these wont drain and give correct info to printer. You can very simple refill them with dye ink. Dye ink only!!!

First, wouldn't print black, now won't print magenta- all new cartridges!

Unplug machinepowercord. Open printer and take all carts out. Plug in power. Machine demands carts. Put new one in: Replace with original ink carts!. When asked push 1 (yes New cart). If you have used thirdparty carts, there could be a prob due to construticon or ink quality. In case there is no bk after 3x cleaning cycles anymore, the head is clogged: This happens because the filter in front of the nozzels is clogged by pigmented ink. DO USE ONLY DYE INK for all types of brother inkjet machines!!!
