SOURCE: Black 3ek cartridge not printing

I had the same problem before with 3e black ink. It simply does not print too, so what I did if i get to print black and white i will set the characters into dark gray! it looks like draft printing but the things is it can be printed.. I tried to do every instructions available but to fail. I almost dump it till I decided to set it aside for a while. After a week I tried using it again, and it functions well. I guess the printer just want to say, "HEY BUDDY, GIVE ME A LITTLE BREAK!"

SOURCE: Print Cartridge Problems

I just replaced both the black and color cartridges (empty) with new replacement cartridges - Office Max brand. I couldn't get any e-mails or documents to print, although I could get ink on paper when running the Nozzle Check and Print Head Allignment. That doesn't make sense!

I e-mailed Canon Tech Support and was told to use only Canon cartridges. I bit the bullet, went out and bought another black cartridge - this time Canon brand, installed it ,and my printer now works - including color printing.

The color cartridge is still office Max brand. My printer now says I have black ink, but still says the color ink is low (even though it's full).

Conclusion: The Canon printer only works properly with Canon cartridges!

Use original cartridges. Generic or refilled cartridges tend to cause these problems.

I had this problem several times, had to buy new print head until I found that to clean it you should use ammonia. It really worked for me. You should really try ammonia it does work.

Service error 5100


Unplug for 30 seconds then replug, clean the cartridge's contacts, check and make sure the encoder strip is not out of place behind the carriage. Do a full cleaning of the print head manually:

(1) Open the printer
(2) Remove the ink cartridges from the print head.
(3) Use cotton swabs dipped in hot water to thoroughly clean the print head.
(4) Repeat this until there is no ink residue coming off on the cotton swab.
(5) Once finished, allow to dry and replace the cartridges
(6) Try to print something now

If none of that works, most likely you need a new print head.

Hi, i'm getting error message 1203 on the printer and we've lost the user's manual. Can you tell me what this is?


Error 1203 is a very interesting error code. Here is what I found out about error 1203



Error 1203 is a very interesting cartridge error. It means your cartridges overflow even from brand new cartridges after a several prints or right after you refilled the cartridges. Check to see if ink are smeared on the holder where the contact panel with the cartridge


Solution:
I use the lint free cloth(coffee filter work great) with a few drops of water to dampen and clean off those contact on the holder and my printer work again.
Then before you print anything, you should run aligned the cartridges a couple times then run clean cartridges a couple times.
Print the test page to see how it's look and way you go.
Be sure not to leave any debris of lint free cloth(coffee filter work great on those holder contact panel.

About a month ago, I bought new cartridges for my Epson NX400. It will print every color but the black ink on the test pages and on the things I print out. However, I have only printed one page since I got...


Black printer ink in HP Printer may fail to be recognized by the printer. Most times an error message will be sent indicating that something is wrong with the black print cartridge. Sometimes the printer may accept to print with the black ink, but the printouts may have horizontal lines and very illegible letters. In such a case a manual cleaning of the print head should be carried out. In doing the manual cleaning, one should spray Windex heavily on paper towel and wipe off the surface of the print head.

Printer will not print red. The red cartridge seems fine, with ink flowing freely, but it won't print onto the page.


its the problem of print head in your printer. You are not the only one facing this problem there are many other users facing this same problem.in canon printer users out of 10 users ---- 8 users face this problem.
Now I will explain the problem
In the printer where you insert the cartridges is called carriage.in the carriage there is a part called PRINT HEAD. In the print head there are tiny – tiny holes from where the ink passes.when you insert the cartridge in the carriage /head of the printer the ink from the cartridge passes from the head.but if the head is got blocked then the ink will not pass from the head and you get no print out still with the new brand cartridges.now in the printer there is a in built cleaning assembly , so when you give the command of cleaning from your pc/laptop the inbuilt cleaning assembly tries to clean the blocked ink in the tiny holes of the head.but if the ink is got stuck up hard the cleaning assembly in the printer does not have that much power to clean the ink in the head.the other procedure to clean the head is a manual cleaning.in this procedure the head needs to be removed from the printer by disassembling the printer.but in this case out of 100 only 4 to 5 heads gets cleaned and start working but that also don’t last long.its not any guarantee that how much the manually cleaned head will work.
In some cases it has been seen that ink gets used only in cleaning but after inserting new cartridges the printer starts working.if you have inserted new cartridges in the printer and still don’t get any printout then its advisable that you go for any other brand printer.hp is the best brand of printer. Or the other option is you take the printer to local printer repair shop to get the head manually cleaned if you at present don’t want to invest in new printer.a repair center have some special tools to clean the print head its 50 ---- 50 Chance.you can try that first.
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

I replaced both ink cartridges for the printer, won' print.


Please follow the procedure your printer has which forces it printer to clean the print heads.
I have experience of other epson stylus models.  I have previously spoken to epson about this exact problem.  Repeating the head cleaning process a minimum 5 times cleared the problem.
Running head clean multiple times in succession builds up pressure in the print heads - causing (usually new) cartridges to work correctly.
kind regards

Epson 830u printer


Many problems about printer heads but most common causes are it was not installed properly in the printer. Try to check if the printer is on when you get the cartridges. it will damaged the printer if taken forcibly.
Here are some suggestions to do:

1. Check your complete set of ink. I it is filled with the color indicated.
2. if you brought a new one it must be sealed.
3. If tampered or the package is open, it may have been used by somebody.
4. Install the printer cartridges properly using the guide/ user's manual so that cartridges are taken cared off.
5. When cleaning the print heads do not put much force because print heads are sensitive. Colors from yellow, magenta, cyan and black are very small so take care of cleaning. I possible use tissue because it absorbs well without blocking the jet pin of the print heads.
6. When new settings are applied you must restart the PC so that new settings will take effect.
Thanks
