There is a firmware update for the canon i9900/i9950 at this address http://alpha02.c-wss.com/inc/ApplServlet?SV=WWUCA900
The updated ROM version (1.05) for the i9900 printer does two things:
1. Protects the print head from possible damage when changing ink
tanks.
2. Resolves an issue where, under specific circumstances, noticeable
black lines appear when printing in grayscale.
