I had a HP printer that refused to accept refilled cartridges. Finally dumped it for a Canon that does take refilled cartridges, but just hit a limit on the Canon where the tiny little sponge pads that soak up excess ink are supposedly too full. Error message says to get it serviced. I found a video that shows how to remove the sponges, clean them out and replace them, but you have to hard reset the printer to clear the counter so it has to be reset to the wi-fi. Can’t find anywhere to just buy new pads (which look like they should cost a nickel apiece), so I guess I’ll do the cleanup and reset when I get time. Wonder how many folks take their printers to get serviced for this?
Can you remember where you found that sponge cleaning video?
May need it soon.
