Question about Canon PIXMA MP780 All-In-One InkJet Printer

1 Answer

Main black print(BCI-3eBK)seems clogged and nozzle check shows only partial pattern. The cartridge seemed to be stuck to the print head. This happened before about two months ago. My technician cleaned it. Should it be cleaned again or is a new print head needed? What other items should I order for maintenance?

Sounds like you need a new printhead, and the only thing you need for cleaning is a damp cloth. All the Canon inks are water soluable. The printheads don't clean very well and don't last long if you do clean them.

Dear Adrienne,First make sure that the black ink is not empty. If you are sure the black ink is full enough you need to check the print head condition. The print head may be clogged or faulty.
To fix the clogged print head,please perform the following step:
  • Print the nozzle check pattern, access the following menu on LCD: Menu>Maintenance>Nozzle Check. The good nozzle pattern should like below sample image.

  • If the print head nozzle missing some color (i.e Black) the perform print head cleaning: Menu>Maintenance>Cleaning. Then print the nozzle check pattern again. Note: you may repeat this step up to 3 times.
  • If the problem still remain,then you should perform Deep Cleaning: Menu>Maintenance>Deep Cleaning.
If you have perform the above steps but the problem still the same,please check whether the black nozzle missing partially or totally. The faulty Purge Unit (ink pump) may cause the same problem. I mean the purge unit does not work properly so the ink cannot flow. Good luck :)

I have been using an epson stylus color 880 for years. One day it would not print. Replaced the cartridges and still will not print. It goes through the printing procedures but nothing shows up on...


The print head nozzles may be clogged. From the Utility section found in the EPSON printer driver, clean the print heads by performing a head cleaning followed by printing a nozzle check pattern. A head cleaning and nozzle check must be performed as a cycle. After printing a nozzle check, examine the printed dot pattern. Each staggered horizontal and straight vertical line should be complete, with no gaps in the dot pattern. If there are gaps in the dot pattern, continue with another cycle. Perform up to 3 cycles if necessary. If the nozzle check is not printing completely, and if the head cleanings do not help the nozzle check pattern to print completely, try replacing the ink cartridge. Any ink cartridge installed into the printer must have a blue label on top of it. If the blue label has been removed from the ink cartridge, do not install the cartridge. Using an ink cartridge, which does not have the blue label on it, may damage the printer. Caution: If you have already installed a cartridge which is missing the blue label, or if a previously installed ink cartridge was missing its blue label at the time it was installed, and now head cleanings do not help the nozzle check pattern to print completely, your printer may require service and you should contact the EPSON Connection for further assistance.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response

Thanks, Joe

Colour ink not printing


If the printer is printing blank pages, make sure you are using the correct printer driver and make sure the paper size is correctly selected in the driver. If the printer is printing black only, the "Ink" option in the printer driver may be set to "Black" instead of "Color" or a setting in the software may be set to print black only. Also, the print head nozzles may be clogged.

A head cleaning and nozzle check must be performed as a cycle. After printing a nozzle check, examine the printed dot pattern. Each staggered horizontal and straight vertical line should be complete, with no gaps in the dot pattern. If there are gaps in the dot pattern, continue with another cycle. Perform up to 3 cycles if necessary. If the nozzle check is not printing completely, and if the head cleanings do not help the nozzle check pattern to print completely, turn the printer off overnight and try the cleaning cycles again.

Try a new ink cartridge. Also, make sure you are using a genuine ink cartridge and has the same number as your old catridge.

Despite cleaning ink head many times, the yellow cartridge seems blocked as colour not showing


You will have to clean the print head, not just the ink cartridges. Here's how to clear blocked print heads:
-run several head cleanings and print the nozzle check pattern
-if that doesn't fix it, remove the cartridge(s) from the blocked head and drop alcohol where the ink enters the printer.
-reinsert the cartridges
-run one head cleaning
-wait about an hour then run some head cleanings.
-if no luck, you may want to dip the print head into Isopropyl Alcohol overnight (can get it from chemist)
-if it still doesn't work, your print head may be clogged to the point where it needs repair or replacement, which will probably cost more than a new printer.

I have a Canon Pixma MP270 and I can only print in colour both the black and colour lights are lit up on the printer


f print quality does not improve by the standard cleaning of the Print Head, clean the Print Head deeply. Cleaning the Print Head deeply consumes more ink than the standard cleaning of the Print Head, so clean the Print Head deeply only when necessary.
1. Make sure that the power is turned on.

2. Clean the Print Head deeply. (1) Press the g0022565.png (Maintenance) button repeatedly until y appears. g0054776.png
(2) Press the Black or Color button.
The machine starts cleaning the Print Head deeply. Do not perform any other operations until the machine completes the deep cleaning of the Print Head. This takes about 2 minutes.

3. Check the print head condition.

When the deep cleaning is completed, the LED returns to the copy standby mode. To check the print head condition, print the nozzle check pattern.

See " Printing the Nozzle Check Pattern".

If the problem is not resolved, turn off the power and clean the Print Head deeply again after 24 hours.
If the problem is still not resolved, replace the FINE Cartridge with a new one.

See " Replacing FINE Cartridges".
If the problem is still not resolved after replacing the FINE Cartridge, contact the service center.

Printing the Nozzle Check Pattern
Print the nozzle check pattern to determine whether the ink ejects properly from the print head nozzles.

NOTE If the remaining ink level is low, the nozzle check pattern will not be printed correctly. Replace the FINE Cartridge whose ink is low.
See " Replacing FINE Cartridges".



You need to prepare: a sheet of A4 or Letter-sized plain paper

1. Make sure that the power is turned on.

2. Load a sheet of A4 or Letter-sized plain paper in the Rear Tray.

3. Open the Paper Output Tray gently, and open the Output Tray Extension.

4. Print the nozzle check pattern.

(1) Press the g0020617.png (Maintenance) button repeatedly until A appears. g0054754.png
(2) Press the Black or Color button.

The nozzle check pattern will be printed.

5. Examine the nozzle check pattern.
See Examining the Nozzle Check Pattern.

Examining the Nozzle Check Pattern

Examine the nozzle check pattern, and clean the Print Head if necessary.

1. Check if there are missing lines in the pattern (1) or horizontal white streaks in the pattern (2). g0054755.png (1) Check if lines are missing in this pattern. If yes, the cleaning is required.
See " Cleaning the Print Head".

g0020623.png
(A) Good
(B) Bad (lines are missing)

(2) Check if horizontal white streaks are present in this pattern. If yes, the cleaning is required.
See " Cleaning the Print Head".
g0020621.png
(A) Good
(B) Bad (horizontal white streaks are present)

Cleaning your head might resolve your problem. Perform the below steps to clean the head:

Print Head Cleaning / Head Refreshing If the printed nozzle check pattern is broken, missing, or a specific color is not printed, clean the print head (Cleaning) or print head deep cleaning (Deep Cleaning). Note:
  1. Cleaning the print head consumes a small amount of ink. Cleaning too often reduces the amount of ink in the ink tanks.

  2. Print head cleaning is performed when you connect the power cord. Your machine may perform print head cleaning periodically to avoid clogging.
Overview:
Step1:
Print the Nozzle Check Pattern.
To check whether the print head nozzles are clogged, print the Nozzle Check Pattern.
downicon.gif If the print quality is poor, perform print head cleaning.
Step 2:
Perform print head cleaning.
This unclogs the print head nozzles
Print the Nozzle Check Pattern again.
To check whether the print head nozzles are clogged, print the Nozzle Check Pattern.
If the print quality is still poor, perform two print head cleanings.

Step 3:
Perform deep print head cleaning.
This is a more powerful cleaning.

  2. Press the up or down cursor to select [Deep cleaning], then press <OK>.

    mp800_deepcleaning.gif

  3. Press the up or down cursor to select [Yes], then press <OK> to start print head deep cleaning.

    Note:
    Do not do any other operations until print head deep cleaning is completed.


  4. Print the nozzle check pattern and check the print head status.

    Note:
    If the printed result does not improve even after doing print head deep cleaning, turn off the printer. Then, after 24 hours or later, do print head deep cleaning again. (After a given time interval, ink could dissolve itself, resulting in ink unclogging.)

Canon ip4000r doesn't print 3ebk (black)


First of all... have you tampered with the printer's firmware? If not, it's unlikely it became corrupted. But if replacing the ink cartridges with fresh ones, and using a new print head did not fix your problem, you may be out of luck.

Is this a new problem, or has it always been like this?

Could it be that the print driver is always printing photo? In that case, it uses the narrow black ink cartridge instead of the fat 3eBK cart. You should print a nozzle check pattern and verify that you see the 3eBK cartridge pattern. If you do, the problem is likely SOFTWARE... your driver settings, not the printer itself.

I hope this helps.

PIXMA MP780 printing trouble


If you haven't done so, I would try another new cartridge. It is entirely possible (and occurs frequently) that you got a bad cartridge. Assuming you removed the tape from the cartridge before putting it in, this is generally indicative of either a bad cartridge, bad print head, or that heads or ink tanks may need cleaning.

The Canon support page for this printer is at:
http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=SupportDetailTabAct&fcategoryid=238&modelid=10444

However, as Canon pages come up as generic pages (without the text I input for you), you will have to type in "missing black ink" (without quotes), to see the material they have posted in this regard. You will find instructions there in regard to how to clean the print heads, etc., if that is necessary. However, I would definitely try another cartridge first, especially if you haven't had that much use on the printer, such that you think these other measures may be necessary.

Please post back if you need further help, otherwise thanks for rating FixYa!

Ink Tank not showing up


That's a BCI-3eBK cartridge. Most Canon inkjet problems can be resolved by replacing the print head. eBay is the best place to find a replacement.
