Question about Canon FAXPHONE B640 Plain Paper Bubblejet
Mater478.....did as you suggested, but the unit still told me to change the cartridge. I ordered a replacement a few minutes ago. I have another problem also. After cleaning the cartridge and reinstalling it the unit failed to reinitialize the cartridge assembly. This has happened since I tried to use the unit earlier this morning. I haven't used the B640 for about six months. Any suggestions? Thanks.

Hi i am a certified Canon repair tech for this fax. the problem that you are having is very common and has to do with two things. the cartridge and the purge/cleaning unit. what you can try is this open the printer and center the carridge unit and remove the cartridge. unplug the machine while it is still centered. on the right hand side you will see the purge unit. in the center of the purge unit is what looks like a retanglar pad. mix a water soap solution and apply to pad just soaking it. let it sit for a few minutes. take the ink cartridge and wipe the bottom of the cartridge with a damp soapy cloth. also if you look at the cartridge there is a little breating hole you can hold a cloth on the bottom and gently blow in that hole it will purge ink through the bottom of the cartridge. install the cartridge in the machine close the front door and replug in the power cord. you might still have to run a few cleaning cycles. hope this helps.
