Question about Office Equipment & Supplies
Changed the ink cartridges and initially got error code 133 Needs inspection. Turned the machine off manually since it wouldn't turn off any other way. Now it is showing off/on error: 811. All the lights on the control panel light but it won't do anything. Can't find any info on either error code.

I added my post today with the same problem, and thought I'd share what I since learned. Apparently this "Alarm light/U150" is common with several Canon models. The U150 indicates a faulty electronic chip (on the ink cartridge). Though I tried cleaning the sensor with isopropyl alcohol, and also tried removing all the cartridges, unplugging the printer for 45 seconds, then reconnecting,etc. as I had read might help, I still had the same frustrating problem. Contacting Canon was the solution that worked for me. First I emailed, but decided I didn't want to wait for their response. A call to Canon Tech Support (1-800-385-2155) was quick and painless. They will more than likely send you a new cartridge, but you'll need to have your serial # & date of purchase handy.

HI. Try holding the reset button for 6 seconds to overide the error. This may dissable the chip so it won't report but will allow you to keep printing. Simply check the ink tanks visually.
Refilling will give the same error too, again dissable the error.

If the printer worked one day and stopped working after turned off/on, you most probably have a bad paper sensor. This is basically a switch that is no longer working, therefore cleaning will no fix it. Determining which one is actually bad is difficult, so many places actually replace them all. I might be able to get you the part numbers if you really want to try it out. But be aware that this is only an educated guess, your unit might have another issue involved.
