Printer will not print in black from either black cartridge. Cleaning and deep cleaning have not helped. Both cartridges are more than half full.

Hi Carl Montero,
Your issue may be attributed to two possible points of failure. 1.) The Nozzle is clogged, 2.) the ink is already dry inside. You can try to clean the nozzle by doing the following steps. If it does not work, try to replace the cartridge with a new one.
FINE Cartridge Cleaning
1 Press [Menu] repeatedly until appears. 2 Use [ ] or [ ] to select . 3 Press [OK]. 1 Press [Maintenance] repeatedly until appears. 2 Press [Black] or [Color].
FINE Cartridge Deep Cleaning
1 Press [Menu] repeatedly until appears. 2 Use [ ] or [ ] to select . 3 Press [OK]. 1 Press [Maintenance] repeatedly until appears. 2 Press [Black] or [Color].
Note If deep FINE Cartridge cleaning does not improve the print quality, contact a Canon service representative.

Make sure you are using genuine Lexmark cartridges. It could be that your black cartridge needs cleaning. Try to do the Deep Clean Printhead function on the printer. Press Ink Levels -> press More Options -> select Deep Clean Printhead. The printer will then print a clean cartridge nozzles page. If black ink is not printed on the page, you may need to update your printer's firmware. The update corrects print quality issues on your printer. You can easily download and install the update using this link Lexmark Platinum Pro905 Firmware Update. Download and install the Pro905 update. Thanks.

Run head cleaning and deep head cleaning for few times. If it doesnt help, you can try to remove print head, and clean the nozzles with distiled water.
And after that also run few times head cleaning mode.

The problem you are describing is with the black ( BC-10 ) print head and not with the printer.

1. Check your black ink tank and be sure it is not dry.

2. Run the printer through one DEEP cleaning cycle and see if that improves the print.

If your black ink tank is full, and the deep cleaning cycle produces no improvement, you will need to replace the BC-10 print head.

black vertical lines on the printout comes due to some reasons.
1) if the black cartridge is near to its end it will give black lines instead of proper printing.
the cartridges gets over many times due to head cleaning and deep cleaning.in 3-4 cleanings cartridge gets over.in one cleaning 4 ml of ink gets puled out of cartridge.the whole quantity of cartridge is near to 25 ml.
but if the cartridge is full then the problem is of cartridge head .the head is the part in which you insert the cartridges if the head is got blocked internally to its holes from where ink comes out.then there are two methods to clean the head one is head cleaning which you did.the other is removing the head by disassembling the printer and then cleaning the head manually with isoprophyll liquid.but its a time consuming and tough job.a local printer repair center will be advisable,
and in some cases it has seen that cartridge gets air pressure problem inside and due to that it leaks inside the printer so replacing that cartridge solves the problem.also many times the cartridge gets leaked and that leaked ink gets collected and stuck up on the roller of the printer from where paper passes so the strips of ink gets printed on the paper.in this case no head cleaning but cleaning the internal roller of the printer with tissue paper helps.the procedure is called servicing.that can also be done at local printer repair center.or you can do it manually by using tissue paper.but to service whole printer it needs to be disassemble.
check out his option.thanks.

Try deep cleaning the black cartridge in the Maintenance section of the printers properties. Print head might be clogged cli-8m

The other week I had the black print head clog up, requiring daily nozzle deep cleaning [a normal 'ocassional' maintenance function]. Thought I needed a new Print head, so anything worth a try.
I loaded up an old black cartridge [I load all my own......always have] with Isopropyl Alcohol and ran deep clean on that cartridge a couple of times, then repeat printed [6 times] a page full of the number 8 in about half inch character size, to get the alcohol through the nozzles. then Deep cleaned again 3 times, to wash it through the print head.

I reloaded the normal ink filled cartridge and ran the '8' page again till I got good black output. It has now been working without problem, daily, for over a week. Clearly if it's a Magenta only problem, the cleaning as described above would be a bit different, as the magenta is one of 4 colour cartridges.
My printer does quite a lot of work, and was bought at least a couple of years ago, being used daily for alpha numeric and photo printing work. This was the first difficulty I experienced with it.
Hope the above might help.Ken

Hi please try these steps:::

Right-click the printer icon, and then select 'Properties'.
2. Click the 'Maintenance' tab, and then click 'Deep Cleaning'.



3. Select 'All Colors', 'Black' or 'Color' for the print head to be cleaned.





4. Read the message displayed, and then click 'OK'. The power lamp blinks and print head deep cleaning starts. (Do not perform any other operations until print head deep cleaning is complete. Print head deep cleaning takes about 1 minute.)

IF ABOVE STEPS DOESN'T WORK TRY THESE STEPS BELOW

Check ink tank vent hole The ink tank requires air to flow through it so ink can move from the reservoir to the print heads.

1. Confirm there is no orange tape across the top of the ink tank
   
   
2. If the orange tape is as shown in Figure (1), it is properly removed.
   
   
   
   *BCI-3's shown in this example.
   
   
3. If the orange tape is as shown in Figure (2), remove the remaining tape to the level shown in Figure (1).
   
   
4. Make sure each ink tank is snapped into the printer.
   
   IF THESE STEPS DIDNOT WORK THEN YOUR PRINTER NEEDS REPAIR(You might need to change the printer head.)
   

open your list of printers. r/click on the 780 and open properties. fo to the last tab "maintenance" and run cleaning 2 or 3 times then run deep cleaning 2 or 3 times. and see how this helps. If you've never done it before you might want to take out the print head and clean it with alcohol. Take out all the ink like you were changing them then reach in and gently pull out the container that holds the ink. This is the print head. Clean it and replace it, then run clean and deep clean again. run Nozzle check to see how clean it's become and you'll definetly see a difference in your printing. good luck
