I just got my Canon Pixma 5000 printer back from cleaning and servicing and am using my second 5000 now and will continue to use it until it has problems. I want to store the serviced unit for about a year and thought that since I am inept at cleaning the head, purging etc., that I would simply take the print head out and as well the cartridges and buy a new print head and put it in at the time of use. I saw a similar query, but more about a purchase of this unit by a member a few years back and a Canon Rep who participates regularly in Mac Rumors replied. I am hoping that this member "Prelude2Tragedy" might reply to this and advise of what I should do as I don't want to ruin this excellent printer. I look forward to comments. Thank you for your time, I am new here. BTW, I am not into 'instant messaging' which the member described above shows in his/her profile otherwise I guess I could have sent a PM. Thank you. The thread that this member posted a reply to was back in 2005.
