Question about Canon FAXPHONE L80 Laser

1 Answer

Blank vertical lines

When receiving a fax or making a copy there are blank vertical lines. We can't read any of our faxes because it blanks out sections of the fax and cut words in half. I've already followed the instructions for cleaning, didn't even improve the problem...its as bad as ever.

Re: blank vertical lines

Make sure you have good OEM supplies installed. Use a good vacuum and clean the toner from the laser scanner window.

Whenever i send a fax, the machine confirms by viewing 'TRANSMITTING OK' but the addressee receives a blank document

Check the baud rate of your transmissions. Slow them down to the slowest setting and send a test fax to a helpful person. Slowly increase the baud rate (communication data speed) and send the fax test. When the fax doesn't show up on the receive site, then step one baud rate speed back, and save the setting.

It could also be your fax that is faulty, or even the receive sites fax, also being faulty.

To test your copy-head, insert a document into your loading section of the fax and press copy. If the copy prints out fine, then you know the head is reading correctly.

It is also possible that the receiver fax (the other end) has a printhead failure.

Outgoing fax was received as blank


Make sure that you sent the fax face down.
If all your faxes are sent blank, there may be a problem with the scanner. Try making a photo copy placing the page face down, if your copy comes out blank then the scanner is finished.

If your photocopy does not come out blank then the problem is on the other end and not your machine.

You have white out or some other white substance blocking your scanner optics. I am assuming this is a thin blank line. What you need to do is make a copy of a document with your machine. You should see the very same blank line on your copy that your customer is seeing on their received fax. Now take this copy and place it in the document feeder the same way you placed the document when you made your copy. Now imagine this document going thru the feeder. The strip that is blank will "match up" with the white out or whatever is causing the blank line. You just need to open up the feeder section where the documents go in to be scanned and look for the thin strip of glass that runs from one side to the other. Using the copy you made with the blank line, use it to see exactly where the glass should have something stuck to it and clean it off with a soft clotch with a little glass cleaner on it. Go ahead and clean the while glass while you are in there. Once clean you can close it back up and run another copy to insure that all the lines are gone.
Good Luck and Thank You for using Fixya.

The machine told you poor line quality. Try a different phone line to verify. Try it at a friends house to verify it. If you are using Vonage, that is the problem. I have Vonage and every fax I test with has some issues with poor line.

Vertical lines

1st print a report, can you see the lines? Then either the drum is faulty or the laser scanner is. If the lines are not present when printing a report, make a copy and see then if the lines appear. If so, the scanner is faulty. Try cleaning the glass with glass cleaner. However, blank lines mean that bits are missing from the scanner itself and the scanner will need to be replaced.

Can not receive faxes or blank pages com thru!

Can you make a copy and get a good print? Does the blank pages come from different people? If you still get a blank from making a copy, then try a different toner and or drum unit. Hopefully it is still under warranty.
