    i have the same problem as psc 750 blues: replaced cartridges and now get error: incorrect cartridge. Will not print test page.

    same thing for me. I have now tried 3 different new cartridges and all give the same error message. It is scanning fine, but won't do anything else. I have tried to turn on and off the ssystem and have hooked the printer to an alternate computer as well, but no luck. I am ready to toss it out and go get a new one.

I read on another site to wet a q tip and clean both the contacts on the cartridge itself and on the cartridge holder. this did help and I didn't get the error message again. However, now I am wondering if my "new" cartridges are just too old. the site said that they go old rather quickly if not used. he recommended wetting the bottom bronze strip with a wet paper towel and shaking it a bit to loosen what could be hardened ink.

good luck!

My hp psc 750 all-in -one printer scanner not working

A friend of mine had a HP printer (Not a PSC 750) that he had simply plugged into his computer and was able to print properly but received the "options not set" message when he tried to scan.

The solution was to install the HP driver package for his printer.

If you are using the default Windows drivers for your printer you may need to install the HP driver package to access all of your printers functions.

Will not print

So, the printer works just fine but won't talk to the computer. Don't know if it ever did. Needs software and driver to do so.

Color cartridge wont print

The color cartridge is defective. Sometimes, when the printer detects a refilled cartridge, it "marks" the cartridge as defective hence the refilled cartridge will not work on any printer.

Had the same problem. Cleaned the copper-colored "contacts" on the actual printer. Where the printer and the cartridge touch ... you will see them when you take the cartridge out. Hope that helps.
