Sketchy printing the printer is printing so that everything it prints in black ink is incompletely inked. How can I fix this?

Inkjet printers need to be used frequently to prevent ink drying out and blocking the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages, then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer than replace the print head.

Try to change the inkjet cartridges for the black and color because you may only be able to get no more than 105 pages out of a cartridge, assuming it hasn't gone through a cleaning process which uses up a lot of ink.

Unfortunately, most ink jet printers have very expensive ink for printing small jobs, compared to say a laser printer.

quite often inkjet heads will dry up and clog. try a clean heads sequence in the printer properties panel. do this until it prints the clean nozzle page properly. If the ink cartridges have the print head attached to them (some dont) you can dab them on a paper towel with windex or vinegar until they show a nice clean line when dabbed. if you cant get the print heads out , then you just need to continue running the clean nozzel application until it prints the test nozzel job properly. This is the reason I will not buy any more inkjet printers. only Toner based machines. cheers.

My Canon printer has TWO slots for black ink cartridges. I assumed one was extra and didn't replace it when I ran out. Text printed just fine with only one installed, but my photos were printing with purple instead of black. I looked into it, and the two cartridges are different: one holds dye-based ink, the other has pigment based. Photos must require both kinds. If your printer is the same as mine, use both!

Apparently I just had the same problem and I managed to fix it! Click on the OK button on the printer to ignore the low ink level error, then you'll be able to print and scan.

- Try to reallign the cartridge, run a print test, after that if the issue still persist - uninstall and reinstall software - run test and re-allign again the cardtridge using software. run print test again.

I changed the black ink in my printer, now it will not print everything in black!, I changed it back to the old ink, but still not printing black ink, what do I do?

MY DELL 725 PRINT WILL NOT PRINT IN BLACK INK. I HAVE A NEW PRINTER. I EVEN BOUGHT A NEW INK CARTRIDGE AND IT STILL PRINTS IN GREEN ONLY. WHAT CAN I DO TO HAVE MY DOCUMENT PRINT IN BLACK?

go into your canon control panel and hit align ink
that should solve your problem

Replace Black ink cartridge with New HP one, should print same problem in write too if this is the right fix
