This necessitates going into a service mode for the printer, so should be used with care. As long as the ink warning light isn't flashing, you can use this technique with quite low amounts of ink in the cartridges.
| Just remember that messing up your machine by doing something like this won't be covered under warranty!
Use at your own risk |
It involves simultaneously holding down the "Pause (II)", "Down (v)" and "Right/Menu (>)" buttons (on the control panel) as you turn the printer on.

As this procedure is one we've only recently been sent, we'd appreciate feedback on its use
The ink swap procedure
First make sure the printer is turned off.
Remove the ink cartridge you wish to change (Matte or Photo Black) and put the new different Photo or Matte Black in.
Turn on the printer and make sure to simultaneously hold down the Pause(II), Down(v) and Right/Menu(>) buttons at the same as you turn the printer on.
The power button only needs a short press - hold the other three down until the display appears.

The LCD display will show 'SELF TESTING2'.
Wait for the printer to start up fully - paper is not needed at this stage.
Press the Right/Menu(>) button.
The LCD display will show 'Test'.

Press the Down(v) button to scroll down until 'Parameter' appears on the LCD display.

Press the Right/Menu(>) button.
The LCD display will show 'Initialize'.

The black has now been swapped, but there is still old black ink in the line to the head.
Note - We have not tried this technique on a 4880 - use at your own risk
- When we used the similar technique on our 7880. it went into Ink Charge mode when switched on. If this happened on a 4880 (let us know if it's a problem) then I'd look to reset this in the same way as the 7880 (Stage 4). The menu layout is slightly different, but similar enough that I'd expect to follow the sequence. I'd certainly not follow the printer instructions to start the fill procedure - that's lots of ink flushed away.

Flushing the old black ink
Turn on the printer as you would do normally (i.e. no buttons held down)
You have now swapped cartridges, but there is 'old' ink in the lines leading to the print head. You can flush this out by printing something solid black
On your computer
- Open Photoshop
- Create a document the width of your paper 17" x 20" fill the page/document with BLACK - RGB 0, R = 0, G = 0, B = 0
- Print the document with NO COLORMANAGMENT and at 720 DPI.
- You may need to use a custom print size, however you could easily print out on A4/letter sheets of copier paper. Put each printed sheet next to one another and print one at a time. You should be able to see where the black changes after a several sheets.
The amount of ink required to purge the old black depends on your printer.
The SP7880 uses about 10-12ml of ink before the tube is flushed out.
Printing a solid black image of 17"x30" should suffice.
For Mk -> Pk: When you look at the finished print you see that it starts with matte ink as it looks dark and the rest of the print looks a little dull with Pk ink on matt paper. The system is now charged with photo black.
If you consider that an ink change the 'official way' wastes appreciably more ink, you can see why there is such a huge saving.
If you've wondered what over a hundred pounds worth of waste ink looks like - see here :-)
Note -- On our 9600 we printed four 40"x10" solid black rectangles on cheap matt paper to purge the black line. The first 3 were a dark black and the third much lighter as the Photo black ink was used.
Thanks to an industry insider for pointing us to this one!
