Q: My Canon Pixma Pro 10/10s is giving me Error 1000, how can I solve this?

A: Error 1000 on the Canon Pixma Pro 10 and Pro 10s refers to the printer being unable to align the print head from the initial set up because there is no paper in the rear paper tray. This model has two paper trays near the back of the printer, the rear paper tray is the one above the other paper tray, which is the manual feed tray. 

To solve this and set up the printer properly, you have to put the paper in the rear paper tray and not the manual feed tray which is located near the bottom of the printer.
