Question about Canon FAXPHONE B640 Plain Paper Bubblejet

1 Answer

Scanner feed hangup

Canon Faxphone B640: In feeding the original for faxing and copying, the first page comes through with a slight tear slightly to left of center. sometimes I have to hand feed it. With subsequent pages, they start to feed and then often hang up, requiring a "force feed" which sometimes fails. I think that one of the black tabs that covers the white plastic in the assembly that engages the feed roller is broken. There is a long one to the right, but the one to the left is evidently broken. 
Can I fix this, or must I send it to Canon?

    I ended up taping a small piece of stiff paper to the separation pad to replace the broken portion. Seems to work OK, though it seems a bit funky.

Can't fax or copy on brother mfc3240c machine


Sounds like you may have a small obstruction in the scanner feed. This would inhibit making copies and sending faxes. Lift this section up slightly to inspect for small pieces of paper or dust. Blowing it out with compressed air would also be a good idea.

Canon B640 printing problem


The scanner lamp is not working. When making a copy, the lamp lights the source document, so if there is no light, the source document 'looks' black. Your machine will need to be serviced.

Faxes being sent but stuck in memory, How do I Print them out?


Printing Documents in Memory: From B640 Manual

Except when you run out of paper, the faxphone will automatically print out the contents in memory when you remedy the cause of the problem.

If running out of memory caused memory reception, adding recording paper and press {STOP} to begin printing the stored page(s).

After printing the page(s) in memory the faxphone erases the documents from memory.
