TS6420 has stopped printing and copying, error code 2500

[kwagner]

Canon Pixma TS6420 - has been working great for years.  I went to print from my MacBook Air today and it made printing noises for a very long time and eventually produced a blank piece of paper with no printing.  Ever since, all attempts at printing or copying results in the same behavior - a lot of internal noises for a long time, then a blank piece of paper.  The first time it did it, it "may" have shown an error code of 7500 but I could have misread that. 

I have powered it down (from front panel and unplugged it). I have reinstalled the drivers to my laptop.  I have performed a factory reset from the menu.  I have removed and reinstalled the ink cartridges.  All with the same results.  A nozzle check only produces a blank piece of paper after a long time.  I tried a printhead alignment and it ran for a long time then failed (I believe the code was 2500).  

Help and Thanks!!!

Your Canon TS6420 error code 2500 means the automatic print head alignment failed, often due to clogged nozzles, wrong paper size (not A4/Letter), or strong light on the output slot. To fix it, clear obstructions, ensure you're using A4/Letter paper, reduce light, run a nozzle check, and retry alignment; if it persists, press OK to cancel and perform a manual alignment.
