My printer stopped printing magenta, then after trying to clean the nozzles the yellow stopped. Looking inside I saw the tubes with ink were empty. Looking through the manual(s) it looked like I need to do a ink flush or system cleaning but when I tried that it beeped and starting showing error code 5B00. I've found some reference to putting it in service mode to reset a counter, is there any official documentation on that?
The printer is about 2 years old and still on the initial ink and I recently had to replace a warped print head.
