I have a problem with the magenta on my Pixma 4850. I have tried Propanyl to no effect. Was thinking of filling a spare cartridge with propanyl and running through loads of magenta prints. Is this a good idea?

No, don’t attempt to print with anything in the carts other than ink, you risk losing your print head...
If you have a problem with your Magenta, then use another known good cartridge, it doesn’t necessarily have to be magenta, just swap over the chip...

Thanks for the reply. I had presumed that it was a clog in the printhead but from what you say am I right in thinking now that it could actually be the fault of the cartridge? I do have other empty cartridges so I can fill another with magenta and give that a go. I no longer rely on the chip as my resetter failed some time ago so don't think that would be an extra consideration.

@ipfken, Ops, running your printer without Ink Monitoring is fool hardy, because it will only be a matter of time before you’ll get caught out without ink in a cartridge, and you can scratch one print head.

The problem with refilling another cartridge is you may fill it the same way as the previous magenta cartridge was filled, and if that’s the cause then you’re just recreating the same issues.

You need to use a new OEM or aftermarket cartridge that you know is good and will work without quibble, as I said any alternative cartridge, because all your trying to do is eliminate ink starvation out of the equation, and 99% of print problems are cause by the cartridges, (Mostly the refiller) ...

Ok so looks as if I may have done some damage....is there anything I can do? The reason I decided to abandon ink monitoring was that I found it inaccurate.

The ink monitoring on the Canon printer was never meant to be accrete, it primary role is to show the user their approx. ink levels and when to change a cartridge safely as it becomes empty**, BUT and this is the important bit to remember.

When using ink monitoring your print head is being protected by the printer and it won’t let anything untoward happen to it, but if your refilling its doubly important to continue to use it, for your own protection.

By disabling the ink monitoring you have released the printer from its responsibility of protecting the print head, which also causes the printer to do more cleaning and purging and generally waste your ink.

Disabling the ink monitoring does not damage your printer in any way, but you do lose your warrantee by doing so, and there’s a greater chance that the print head will come to harm because of poor ink flow in any one of the refilled cartridges.

**When you use a refilled cartridge, you only use them till the reservoir side becomes empty, at the (Low ink warning message) and no more, by doing so, you run the risk of introducing ink starvation on your very next refill.

Despite what anyone thinks, refilling is a complex operation and needs to be carried out to an exact set of procedures, but by varying these procedures or shortcutting the operation for their own selfish reasons, they run the risk of something going wrong. (It usually does)

**In short never run a Canon dye cartridge empty (DRY) if you wish for continued success, there are only two cartridges that can be run to empty safely, pigment PGl-9/PGl-72.
