Hi BAW9DV,
I hate to hear you are having issues. While there will not is not a specific software utility that will complete the tasks desired, maintenance can be completed from the front panel of the unit. Windows also has an application for faxing from the computer as well that may work with this device. Please see the information below that may enable the functions desired.
Faxing:
1. Use Windows Fax and Scan
A. Type Windows Fax and Scan into search box
B. Configure fax machine for use. Click Here to view Microsoft documentation for use. Note: This is a 3rd party website. HP and I are not responsible for content of this site.
C. Select New Fax
Maintenance tasks from front panel:
Running the Clean Print Cartridges Utility Click Here
Printing setf-test page Click Here
Evaluate test page Click Here
Align the Cartridges: Press setup-Press 5, then press 2
If you the work around options are not acceptable the 8600 model would most certainly meet your needs when compared with this unit. However I encourage you to contact HP to see what upgrade options are available for this unit. It will most likely be another Photosmart model/type unit, but in many cases upgrades are offered at a discounted rate to our valued out of warranty customers. Global contact information can be accessed Here.
P.S. If you upgrade through technical support, be sure to ask about carepacks. Extended warranties may also be available at a discounted rate for upgrading.
Hope this helps!
