I've dusted it but it didn't help. How else should I clean it?
I did the cleaning but I didn't get the replace cartridge message when I switched back on. I just got the b200 message again
No, it didn't work. I'm still getting the B200 error
No different. Still the B200 error
Yes, I did suspect it might be an age problem even though it hasn't been heavily used.
It was worth a try
Thanks for your help
