you have to make calibration

check under general reference (link below). it should mention how to fax, e:mail and copy. if you copy to file / pc that should work as the scanner.

otherwise make sure the "scanner" facility is installed as some MFP's do not come with all facilities installed. (and therefore may not give the option on the screen.)

Unexpected image like barcode as shown below can occur when using the automatic document feeder (ADF). You are using the ADF for incoming faxes. So the problem occurs.
If the copy does not look at all like the original document, make sure that no media is on the flatbed glass from a previous copy job.
I hope this helps.

Logic says replace the black cartridge...AGAIN!! However, you can put the machine in 'disable cartridge check' mode which is found in the diagnostics menu. This will allow you to remove/interchange cartridges to help identify problem cartridges. Most importantly this will allow you to identify whether you have a black cartridge slot problem which makes it a machine problem or whether you just have a bad cartridge. First thing I would do is run the machine without the black cartridge and see if noise disappears. Good luck!!

Juliet. Most likely the scanner lamp, or scanner control unit assembly is defective. If you're technically savvy, you could remove the scan glass and lube the shaft that the scan lamp assy slides on. Sometimes that will fix it. Otherwise, the whole top scan unit will need replacing. That could cost over $300 for the replacement.
