    I have been struggling for some time now to find out how much ink is going in the maintenance ink tank, when is it happening and what is the the best practice to avoid it.

    I bought a scale with good accuracy of +/- 0.03 grams and started measuring how much ink is going in the waste tank in different situations. I must point out that all the data I will provide is in grams, not milliliters. I guess they are close enough as measuring empty and full ink cartridge is about 84-86 grams difference.

    The data is collected with 2.040 firmware version. With any new version there may be changes made by Canon and the data provided will no longer be accurate.

    So, it all started when I got the idea to leave the printer always On, so that I can skip the initial maintenance on every power up.

    I had 11 days without printing and I left it on for that time, disabling Auto power OFF in the settings.
    The result was that one of the black heads developed slight clog and there are some lines, which were not so crisp in the nozzle check pattern. There were also some white lines on the black rectangles before every grid, indication a clogged nozzles. So I performed 2 cleaning cycles to get rid of that clog.

    Normal Cleaning Cycle ink usage: 8.2 gr. In my case 16.4 grams for two cleanings.

    There are some details I need to point out about what I learned from the tests so far. The printer has a timer that is zeroed on every print. It has at least two maintenance events I have found so far. First is how many hours from last print power on maintenance. The second is how many hours from last print before/after print maintenance. Executing power on maintenance does not clear any counters! If you make 10 power on/off in sequence it will waste ink every time, no matter how much time there is from previous power on/off. Only a print resets the counter. Nozzle check is also a print, so it resets the counter.
    Measure the power on wastage, without printing, measuring it every day.
    Procedure: I measure the waste ink tank, powered on and then powered off the printer and measure again.

    On after 0-4h: 0 grams
    On after 4h+: 0.11 grams
    On after 5h+: 0.15 grams
    On after 6h+: 0.9 grams
    On after 24h+: 1 grams
    On after 2-3 days: 2 grams
    On after 4+: 3.2 grams

    Here are the numbers for printing after different period of time from last print. This numbers do not include the 0.05grams that are flushed after every print and are mandatory:

    Print after 0-6h: 0 grams
    Print after 6h+: 0.9 grams
    Print after 12h+: 1 grams
    Print after 24h+: 2 grams
    Print after 2d+: 2 grams
    Print after 3d+: 3.17 grams
    Print after 11days: 3.3 grams

    On every print, the printer wastes 0.05 grams NOT 0.3 grams as widely spread information in forums. Maybe it used to use 0.3 grams, but not anymore, I do not know.
    On every false page feed (if you print from rear tray for example, but put the paper in manual feed) it also wastes 0.05 grams, no matter that it never printed anything.

    I was pleasantly surprised that the printer uses NO ink on cartridge change! Tested with two cartridge changes.

    So if you print and power off the printer and then power it on and print after 4 days an 1 minute the printer will waste 3.2 grams on power on, then ~3.2 more for first print and 0.05 for every other print.

    So, considering the following information, if one is planning to print at least once per week, the printer better stays on all the time disabling auto power off function.

    I will travel soon for 20+ days and will measure what is going on after that and post again.

    There have been some suggestions that the printer is also counting how much printing (square meters) it has done and activates more cleaning jobs after some number, but I have no evidence for such actions so far.

    I may measure how much other cleaning modes cost, but not before I need them, as I spent too much money so far for getting this information.

    I returned from my trip and I'm very happy to report some good news.

    There were some frightening information circulating on the net that after 45 days of inactivity the printer will suck about 50mg of ink, but this is not the case with firmware 2.040!!!

    The printer suck the usual 3 grams on power-on and 3 more on first print. The Nozzle check test looks perfect, like I left it.

    So the table looks like this:

    On after 0-4h: 0 grams
    On after 4+: 0.11 grams
    On after 5+: 0.15 grams
    On after 6h+: 0.9 grams
    On after 24h+: 1 grams
    On after 2-3 days: 2 grams
    On after 4+: 3.2 grams
    On after 48 days: 3.16 grams

    Here are the numbers for printing after different period of time from last print. This numbers do not include the 0.05grams that are flushed after every print and are mandatory:

    Print after 0-6h: 0 grams
    Print after 6h+: 0.9 grams
    Print after 12h+: 1 grams
    Print after 24h+: 2 grams
    Print after 2d+: 2 grams
    Print after 3d+: 3.17 grams
    Print after 11days: 3.3 grams
    Print after 48 days: 3.3 grams

    I did find one unreasoned ink waste on one print before my absence, but didn't find time to report.

    After printing 4 pages A3 Luster media I measured nearly 5 grams waste. On one of the prints I got asked to change GY and got long ink agitating after that. I wander if this waste was because an ink finished in printing or because of some maintenance schedule based on area printed. The printed page was not interrupted. Next time I get this unexpected waste I will count the printed square meters and wait to see if there are some rules I can discover. This is for now.

      Bad news.

      With firmware 2.050 I started a print today and was asked to change the maintenance cart (MC) after that there was about 6 min different noises and I got 58grams in the MC.

      Men that hurts!!



      I also experienced power loss for several hours as the power grid went off two days ago for the whole night and my USP run out of battery.

      So the questions are: Do we get this cleaning activated on every new MC? Do we get this cleaning after power loss? Will this cleaning happen if we change the MC before requested by the printer?

      Next things to test:

      1. is to unplug the printer from the wall socket for one night and see if it will get the 58 grams and if not maybe we can add 58g ink price to the price of the MC.

      2. Change MC before it is full.

      So after all maybe it's not about days off...

      Here is a video how 58g waste looks and sounds like:
