On the printer you can press the setup button (has a picture w/ wrench on it below display screen). Then, select option one which is "ink level".

On your desktop you should have an icon for your WorkForce 645 printer. Click on it to open it and under Epson Product Support will be a Check Ink Levels. Just click on it.

You may be able to use the printer software to increase the black level. I found I could do that with other HP printers. I'm thinking about ordering one of these to replace a 7 year old model giving me print head problems.

I am not sure don't have H.P. I always refill when it says low ink. sometimes I take an old used cart. and fill it for mine let it set for about 6 hours then put it in. I am using a Kodak now. Its tricky on some printer.

Go into maintenance menu and check ink levels. You may need to order more cartridges. I get mine thru Lexmark.com. I joined the rewards program and get free cartridges with every five I buy and every five empty cartridges I return.

Once the cartridge trouble shooter alerts you ink levels are low , you have the option to continue with only black ink. However, it may be light (more grey than black) .

Shine a black light on the dry ink and it will become visible while the black light is illuminating the ink. Turn off the black light and the ink will be invisible again.

I've been using the printer for 5 months, and still have not run out of the colored inks. I am not a heavy user for photos, so can't actually directly answer your question. Since no one else has come forward, I thought I might offer a mathematical suggestion.Go to the printer maintenance picture where it displays the amount of ink you have in the cartridges. Print screen that and keep. Print a good number of your photos, over a few days or weeks, whatever, then print out the ink tank picture again. Compare the two printouts for ink levels, and may be able to give some imprecise indication of how much ink you are using.

Yes, you can check the ink levels from the display screen on the printer. I don't have this printer, but I have an MP-600 that you can do that on. If you go to the Canon website and watch the video about the 620, you can plainly see in the video that the same "Remaining Ink Levels" prompt is on the little screen. You simply push the button under that to check the levels. Hope that helps, even though you asked a long time ago. ;)

It appears to be showing the levels. I didn't look at the levels when I first put the full cartridges in, but now after some amount of use, all but the large black and the grey show 3 bars. The large black shows 4 bars. The grey shows empty with a red X, since the kit did not include a grey cartridge, and I refilled the original.

yes the ink is clear when written on paper. not sure about showing up under another black light as I never tried it. sorry. we used these as party favours and they were a HUGE hit.

It shows itself low on ink, a long time before it is really out. I get twice the use on a cartridge that I did on my previous HP.

Are you asking how to distinguish the tint/color in the cartridge? If so, use the color dot pattern over the ink refil holes as a guide.

With the ink kit you will have a disposable syringe (they can be purchased at a pharmacy for 25 cents) for each color. Peel back the HP label on the cartridge and you will see hole where you will inject the ink. Fill the syringe and slowly, very slowly inject the ink. As soon as it looks like the ink is starting to bubble out of the hole, stop. Put the label back on, set the cartridge in a position so the ink will flow to the sponge pad. For the 920 you can dab a wet paper towel (distilled or pure water is best) on the sponge until ink flows. Then you are all set. Remember, less is better than more, and make sure the top label is sealed. You should get ink on the towel which indicates ink is flowing. If not, wait several hours or up to a day. The 920's work very well for this job. Also, if you can, take out your print head and clean it. There are videos on You Tube that show you how to do this. Good luck, hope this helps.

No problems yet, but only one refill. Check to be sure that there is not ink on the chip at the bottom front of the cartridge or on the pins that make contact with the chip. Clean them with a Q-tip and rubbing alcohol to see if that helps. As for the colors, try the cleaning function that was mentioned in another answer. You can also remove the print head to see if there is any spilled ink on those contacts. If all else fails and you are still missing colors, soaking the print head in Windex for a couple of days, then rinsing in water can help dissolve clogs.

Another thing you can try, (that has worked for me when ink is so low that printer will not print, yet there's still ink in cartridge), is to place a small piece of duct or masking tape over the clear part of the cartridge. That's where/how the printer itself recognizes ink levels in the cartridges.
