PIXMA MX490 Print Head Alignment Issues

CanonSellsJunk — Wed, 25 Mar 2026 12:19:48 GMT

Have had this Canon Pixma MX490 since new, always used Canon genuine Ink cartridges (Black only, as I do not use color).

A week ago I got support code 1704, Ink Absorber Full. After researching, it says to hit OK to bypass but eventually it will not let you anymore. I printed all week with no issues, clearing the 1704 code each time I powered printer on. I changed out Ink cartridge Friday after it started fading, and Saturday decided I would clean the ink absorber, which barely had anything on it. A bit more searching, and turns out it is a pre-programmed error code to come on after so many pages printed, not because the absorber is physically full. Also, you need a tool/ software to clear it.

Come Monday morning, first time using it since new ink and cleaning and reinstalling absorber, the alignment is off. Tried the alignment process through printer itself, did not help. Tried to do a manual one via Canon software on computer, and it will not allow a test page to print, saying there was an error. I would imagine this is because of the 1704 code, even though I already clicked OK on printer to allow printing. So I cannot get the values to input, nor can I even get to the screen to input the values manually to try to correct alignment.

At this point, I'm wondering if the ink cartridge itself is faulty? I've put over 40 ink cartridges through this printer in the past few years alone, and never once had an alignment issue. Cleaning the absorber is just removing a thin sponge strip, which wouldn't effect anything on the alignment side.

Yes, I understand it's an outdated printer, but it was working fine up until this point. Just don't want to waste money on a new cartridge to give that a shot if it could be something else.
