    CD/DVD Printer suggestion

    Canon PIXMA iP8750 will print on disks. It will also print up to A3+ paper sizes. I run it using refillable carts & inks from Octoinkjet which makes it a lot cheaper to run. I find it produces high quality prints (for the money) and I love it!

    Difference between CMYK and CMYK + Grey?

    This is a (colour) scan of a 4x6 (colour) print of a B&W test image. I can see a tiny hint of colour in this image that I cannot see in the print. Your trained eye would undoubtedly see things I can't, though!

    Difference between CMYK and CMYK + Grey?

    It does to my untutored eye. It's marginal, though, and I'm sure both printers would benefit from PeterBJ's tweaking techniques. Thanks for the link. I've got a lot to learn and try out - I need (another) rainy day! In any event, I'm very happy with both printers. The 8750 is more aimed at...

    Difference between CMYK and CMYK + Grey?

    Yep, +20 looks about spot on, thanks.

    Difference between CMYK and CMYK + Grey?

    Wow! What a difference! +30 might be a tad too much but I'll carry on experimenting. Thanks for the tip.

    Difference between CMYK and CMYK + Grey?

    Thanks, I did wonder! I'd love to correct it but please would you repeat the link as I couldn't get it to work?

    Difference between CMYK and CMYK + Grey?

    I have an ip8750 (used predominantly and regularly for 4x6 snaps but up to A3+ occasionally) and an mg6650 (used for office documents, usually A4, and envelopes etc.). Both printers use the same 3rd party carts and inks from Octoink (which are great, BTW). I am a rank amateur hobbyist (colour...

    Difference between CMYK and CMYK + Grey?

    That's interesting. I thought the 'K' cart in both 6820 and 8720 is black ink. Is it ineffective in B&W prints?

    Seeking replacement printer recommendations

    I had a Pro9000 mkII. As a retiree, it was a great pass-time - buying empty carts off ebay, learning about purging, refilling and smugly printing cheap A3+ colour prints for my friends and family. Our walls are plastered with large prints of our grandchildren that bring us joy wherever we turn...

    Thanks, Hat. I'll give this a go next refill. Andy

    Non-OEM cartridge maintenance

    I run 2 Canon printers (Pixma iP8750 for photos & Pixma MG6650 for documents) and I could not be happier. Both printers use 550/551 carts and I have used after-market ARC carts and inks from Octoinkjet from the start. What is the life-cycle of after-market carts? Do they need to be purged or...

    Ink compatibility and ARC questions

    They seal the vent hole when the cart is not being used in the printer (just the same as the tape over the vent hole on bought/OEM cartridges). They don't really need to be coloured.

    Ink compatibility and ARC questions

    Thanks, Joe, but this is incorrect (for these carts, at least). The white plug is in the fill hole and the coloured plug is in the vent hole. I contacted Octoinkjet, as suggested by PeterBJ, and got the following response: 1. The vent plug is the one that sits over the sponge part of the...

    Ink compatibility and ARC questions

    The refillable carts have arrived but without instructions. Each cart has 2 plugs - a plain one in the reservoir (for refilling) and a coloured one (coded to match the ink colour) above the sponge. Should the coloured plug only be used when storing filled carts (the equivalent of tape on an OEM...

    Thank you very much for your reply. Very helpful.

    Ink compatibility and ARC questions

    I'm currently running an MG5300 that's on the blink. I've changed the head once and it's failed again so I'm thinking of cutting my losses and changing it for a more recent model. I use a PRO9000 mkII for photos and the MG5300 for documents and as a spare when the PRO9000 is out of action. I've...

    Problems Flushing Magenta Cartridges

    I already did. However, I'm interested in avoiding future expensive head failures by understanding any potential causes associated with refilling used ones.

    Problems Flushing Magenta Cartridges

    I don't drill, but always remove the ball-seal. I suppose the downside of this is a slightly larger aperture for the ingress of detritus. I tried purging with undiluted household ammonia, even "injecting" it with a needle aimed right into the aperture between the chambers. No change after...
