    What's with all the movement inside my Pro 100 before printing?

    I am not sure what you mean. If you mean you will continue printing about every 2 days, then that would ensure your printer gets a good workout and the printhead is unlikely to clog. It also means the 480 hour timer will never expire, since it will be reset when the 120 hour clean takes place...

    What's with all the movement inside my Pro 100 before printing?

    Oooops. Sorry Avolanche, it should have read "O.22ml" not 2.2ml. I have corrected the original text. Just to be clear, I am not saying the printer will initiate a clean if you have not printed for 120 hours. What I am saying is that regardless of printing or not printing, as soon at the 120...

    What's with all the movement inside my Pro 100 before printing?

    Avalanche, the fact that the “action, movement” you notice occurs “before a print" is a good sign that the activity is a cleaning cycle. The duration of a cleaning cycle is typically 60s and uses a bit more than 0.22ml per cartridge (on average) or a total of 1.8ml across all 8 carts. As others...

    More on The Canon Optical Sensor

    A minor update on the parameter values used in the RUI scripts: Looking deeper into the script code, it can be seen there are 18 values assigned for the first (Colour) parameter. Some are duplicated (or triplicated), such as Yellow, which can be “4” or “13” and Pbk which can be “1”, “9” or “14”...

    More on The Canon Optical Sensor

    I did some simulation testing by substituting retrieved values with my own values to see what was displayed. By substituting a “3” for the 3rd parameter, a “?” is displayed to the left of the colour bar. I assume this is what displays if you disable the ink monitor. Substituting a “4” or...

    More on The Canon Optical Sensor

    Mikling, I assume you are using the graphical ink monitor normally associated with the maintenance tab on the printer driver, which also pops up when printing? I have found it to be quite inaccurate when the ink levels are low and as you have also pointed out the graph actually freezes at the...

    The 60-hour Myth on Canon printers (Not Here-say)

    You seem to be ignoring the note at the bottom of the table: *1: If an ink tank is removed for 60 seconds or longer, cleaning is performed.(Cleaning is performed according to the period of time an ink tank is removed from the print head, regardless of whether the ink tank is actually replaced or...

    Synchronise your Cartridge purges to avoid ink waste

    This thread relates specifically to the Canon Pro100S, but more than likely will apply to other Canon printers with 2 or more printhead groups. For anyone who has had a printhead clog on a Pro100S, they will know they have the option of doing a partial manual purge. ie. There are 2 groups...

    Canon Pro-100 User. Some new findings about cleaning cycles.

    So is this couple of seconds the golden 10-20s figure you mention in the 60 hour myth thread? If so, is it possible that the Pro-100 uses 60s? I did not send any print jobs as such to my printer between 17th June and 5th July, which is when I sent a nozzle check to ensure no clogs had formed...

    The 60-hour Myth on Canon printers (Not Here-say)

    My observation is that the Pro-100S is not offered in the USA, just the Pro-100. As far as I have read, the basic difference is that the Pro-100S has slight improvements to the WiFi. From what I can see most Pro users would not be interested in these features anyway. In Australia the Pro-100...

    Canon Pro-100 User. Some new findings about cleaning cycles.

    I guess I am showing my age. What I actually did was send a blank page from a word processor in order to invoke any pending purge. I discovered some time back that that is all that is required to invoke a purge. This way you do not waste any ink if there is no purge waiting and the purpose of...

    Canon Pro-100 User. Some new findings about cleaning cycles.

    Today my Pro-100S Gray cart reported empty. After replacing the empty cart with a full cart, I sent a Form Feed to the printer. There was no purge, which is interesting, because the Pro-100 User Manual says there will be a purge. However, as already mentioned in this thread, the Pro9000 Service...

    The 60-hour Myth on Canon printers (Not Here-say)

    Stratman, you may not have read my rather long winded series of tests I did on the Pro-100S and referenced in my post on Noctivagus thread. I did several tests where I removed cartridges for a timed period then sent a Form Feed to the printer. If a purge did not occur I repeated the procedure...

    The 60-hour Myth on Canon printers (Not Here-say)

    My Pro-100S is about 2 months old. It is still on it’s original set of OEM cartridges and was used daily for the first month, which is when I noticed the purges. I note that Noctivagus’s Pro-100S was about 6 months old when he reported the observations. I promise you my Pro-100S has a 120 Hour...

    The 60-hour Myth on Canon printers (Not Here-say)

    Prior to the thread posted by Noctivagus in December 2017 (re the Pro-100S Cleaning Cycles), there was a lot of misunderstanding about the maintenance procedure of the Pro-100. That misunderstanding had come about, it would appear, because of an incorrect interpretation of the Pro-9500 Service...

    The 60-hour Myth on Canon printers (Not Here-say)

    There seems to be a contradiction in the following statement: Are there some words missing, because I have read it several times and can’t work out what is meant or link it to anything in the Service Manual? For the Pro-100 and Pro-9000 the timers are also different, as there are only 2...

    Canon Pro-100 User. Some new findings about cleaning cycles.

    Thanks The Hat for moving this thread into the Canon section of the forum. I initially felt that was the proper thing to do, but since I did not initiate the thread, I thought the approach I took would at least bring the thread to notice. I think it is worth clarifying here what you believe was...

    Canon Pro-100 Printing Too Dark

    The first step is really to profile the monitor. The next step would be to compare the reference file print to the monitor. But you don't know if the monitor is correct. I would be inclined to say it is not. If you have any Glossy (or even semi-gloss) Canon paper, it may be worth doing a test...

    Canon Pro-100 Printing Too Dark

    Hi Natty, I am no expert, but it looks like you are doing all the right things. I don't have the exact same reference file as yours, mine is actually the top left segment of yours, with the 4 different skin tones. They do look a bit off, but I wonder if that is just all the variable that could...

    Canon Pro-100 Clean Cycles explained

    Yesterday I joined the forum and the first thing I wanted to do was to thank 2 forum members for helping resolve a long misunderstood concept about the Canon Pro-100 cleaning cycles. In Dec last year Noctivagus posted a thread detailing his findings. It did not get a lot of attention...
