Canon pro9000 mark ii error code 6a0011/8/2022 ![]() ![]() There is a narrow squeegee for the black ink at 3, a wider one for the colour inks at 2, and then a full-width one at 1. I used these to clean the ink off the clear plastic "squeegees", these are on a white "L-shaped" piece that moves horizontally, sliding along guides to the lower-right, to wipe past the bottom of the print head carriage. I cut paper towels into 2 cm-wide strips, folded them a few times, and dipped the narrow end in water. Next we need to clean the auto-purge unit. It is really important to not drop the pads into the printer (if you do, you probably won't be able to retrieve it as the printer is ridiculously difficult to take apart and reassemble – especially if it is a multi-function printer such as this). The far tray (and the only one visible in this photograph) is for the colour inks (in this photograph, the pad has already been removed). These pads can just be pulled up by getting your fingernail behind them and lifting. These are in two black rubber trays in the centre of circle 1. The first step is to remove the pads which absorb the ink left on the nozzles after printing. ![]() Belt 2 pulls the print head carriage along the metal rod (which is behind the left 3), and this rod has grease on it, which you'll end up with on the back of your fingers, so don't get this grease from the back of your fingers onto the plastic tape as the print head needs to "see" the fine lines on the plastic tape. Looking in to the printer, the exposed parts of the auto-purge unit are in circle 1, when working there it is important to not damage the thin clear plastic tape 3 which the print head carriage uses to track its exact location. All the work will be done to the "auto-purge unit", which is at the right side of the print head carriage, as shown by 2. While accessing the offending parts of newer models of Canon printers is somewhat easier, it is quite difficult for the MX850. Once you open the printer lid (to access the ink cartridges) and the print carriage moves to the centre, un-plug the printer and push the print head carriage to the left (as shown by 1). You do not need any tools and you do not need to remove any screws or side panels (as I wasted my time doing). You'll also need some water and paper towels cut into strips about 2 cm wide. You'll need to get light down into the lower-right part of the printer carriage area, as shown by 2. This may take an hour or two, so it is worth getting properly set-up. I was so happy that this led me to understanding the problem and fixing it, that I hope this can help others save money and avoid throwing out an (almost) perfectly good printer.įirstly, this problem and the solution is basically the same for many models of Canon inkjet printers, so even if you have a different model, if you have an Error Code 6A00, the following should be of help. Still, there were many different descriptions of the problems and their solution. Much checking on the Internet showed that many models of Canon inkjet and multi-function printers can have this error, and a particularly good page at was here. If the squeegee mechanism won't fully extend and retract, or the pads won't move up (to seal against the bottom of the print head nozzles) and down (so the print head carriage can move freely from its parking position at the right), then an Error Code 6A00 is displayed. When the printer is idle, these porous pads are likely pushed-up against the bottom of the print head to keep the nozzles from drying-out and clogging. ![]() When the squeegees are fully-extended, the ink on them is (mostly) removed as the squeegees pass by a plastic blade that scrapes off the ink, pivots, and dumps this ink into porous pads. The auto-purge unit is three "squeegees" that move horizontally along guides to wipe across the print head nozzles after printing to remove the excess ink. In January 2012, after several years of reliable service, my Canon PIXMA MX850 multi-function printer stopped working with an Error Code 6A00.Įrror Code 6A00 apparently means that the "auto-purge" unit is not operating correctly. ![]()
