How do i scan images using the hp 4730 mfp

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.)

We use HP Color Laserjet CM1017; Magenta color is not printing

Dirty laser unit - needs (careful) cleaning internally.

See ' Printing Weak Magenta', 'Printing Light Magenta' for HP CM1015, HP Color Laserjet 1600, 2600, 2605.

All the same laser unit

Incoming faxes on the laserjet 4730 mfp look like bar-codes. Other print jobs are OK

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.

All the best.
