Having the same problem with my MX5320 that is over a year old. Only using original Canon cartridges. Just finished a print job, when the U052 error came up, then it stopped working, despite resetting and power off. Tried reseating the print head per Canon instructions from various forums, but it still doesn't work!
Any other solutions besides it being a brick?
