Error code 0001900 for ir3300

The error code means the waste toner bottle is full. It may not be full, but once the waste toner bottle neck is dirty and the copier thinks it is full. It's a poor design from Canon. The waste toner is on the left rear side of the copier. It is behind a panel with one screw that holds it in. Remove the cover and remove the waste toner bottle and carefilly empity out the waste toner into a plastic bag. Make sure you clean the neck of the bottle. There are 2 windows on the neck. That is where it gets dirty. Return the bottle back into the copier & return the cover, Then turn the main power switch on the right side and turn it back ON and thats it... Good Luck
