I can't print with the black ink. I performed a print head cleaning, and then I printed the nozzle check pattern. I noticed that the Cyan, Magenta, and Yellow shows up. However, the black checkered...


Simple problem that print head cleaning will typically not fix. The black ink is pigment based so it tends to form more stubborn clogs. Just remove the print head and if you have a steamer hit the black printhead nozzles with some pressured steam. If not available, soak the surface of the printhead in shallow hot water (try not to get the contact wet or be sure to dry them if you do). You can tell if the printhead nozzles are open by folding a section of wet paper towel like 5-10 layers and then soak it, press the printhead surface up and down lightly on the wet paper towel and if the nozzles are open you will see some ink pulse in the black port screen (the colors will also pulse from the pressure of the liquid under the printhead). It's easier than it sounds so give it a try. I've saved 100s of Canon printheads this way.

Note: if you have a really dried out head, you sometimes have to soak from the top inlet ports and the bottom nozzle surface to clear, but unlikely in you case since you had a black cartridge installed with ink in it (this keeps the top port from drying).

I have try to print but its not printing. i've allready fill the ink still the page come out blank.


It could be due to the refilled cartridge that you are using. Refilled cartridges tend to degrade print quality and cartridge performance.
You can try to clean the cartridge nozzles. Please follow the steps below to fix the problem:
  1. On the printer control panel, press Copy.
  2. Press Options until Maintenance is highlighted.
  3. Press the right arrow until Align Cartridges or Clean Cartridges appears, and then press Select. A test page will then be printed forcing ink through the cartridge nozzles and clean them.
Try to print your document again to verify that the cartridges are working.
If that doesn't help, I would suggest you replace your cartridges with new genuine Lexmark cartridges.

I have an hp psc 1215 all-in-one. My black cartridge won't print. It recognises if I swap it out for a new one, and goes through all the motions. It registers the correct ink levels. The cradle...


The problem is not with the ink-cartridges. You've proved that, by swapping BLACK cartridges.

The problem is that the ink-jets that spray the BLACK ink onto the paper are clogged.
Thus, no BLACK ink reaches the paper.

Open the HP Printing Assistant, and open Utilities, and run a few "print-head-cleaning" cycles, to try to unclog the print-head.

All the pages I print are blank. There is sufficient ink the print preview shows the image but the actual print out is blank


Sounds like your print heads are clogged. This is quite common. Go into your printer's menu and find the maintenance menu and follow the steps to clean your print heads. Run the process everal times until the prints are 100%. Then run a printhead alignment. Regardless of whether your not your ink is full, if cleaning the heads several times does not solve the issue, put new ink cartridges in because you may have bad cartridges. If that doesn't work, you've got bigger issues, contact the manufacturer.

My prints are all coming out faded and light- i;ve tried to clean the nozzles and head adjust, the cartiges are all new. Any advice?


Did you use Epson Genuine Cartridges?

ALL…. Epson & Brother Requires Genuine Epson Cartridges. !!!!!!!!
That sounds like your problem.

In Purchasing Epson's CX 5400, CX4600, & CX7400 and more, I found out that Epson does not like Generic Printer Cartridges. I also Purchased a Brother. That also does not like Generic Print Cartridges. Color that should be Yellow, will turn out Green, Blue Brown, etc.

These printers have a CHIP that will detect if it is Generic or Genuine. When they see it’s Generic Cartridges, it will print lines thru the words, stripes across the picture and also do a mix match with the colors. It also will not let you print anything, if only one of the cartridges is empty.

I wanted to print only Black, and would not let me, because I did not have any ink in one of my cyan cartridges. Go figure.

That's what these Companies do., so they can keep selling the ink cartridges. Some Printers, are able to use Generic, and some are refillable. Some you can refill them up yourself and I heard, quite MESSY.

So I learned, thru trial and error, that you must use the ORIGINAL Genuine Cartridges for these PRINTERS. Some people say some models work fine compatible, but not mine.......


I had to replace the printer, but Epson, Lexmark & Brothers are always on sale. My Brother & Epson cost me $50.00 with Rebate. .

This is the only advice I can give you. If you find this helpful, pls rate me.

Thanks and Good Luck :0)

Colour cartridge missing but I only want to print


No you cannot. Each one of your cartridges is smart chipped. When this cartridge registers as empty it acts as an on/off switch thus turning the printer off.'

You need to replace the empty cartridge in order to print.

Go printer settings and check option to print only black.

Printer does not print at all


Did u remove the cellotape that covers the printhead of the new cartridge?
Other solution:
if using XP: use the HP toolbox to prepare the new catridges for firsttime printing.
If using Vista, go to start-controlpanel-printers and rightclick on hp940C icon, choose properties, select services and do a cleaning and prepare job.
