at my company we have HP OfficeJet Pro 7740, it prints good, but scanning to computer work bad. Printer is connected to network.
I have installed OJ7740_Full_WebPack_40.12.1161 to computer. Scan to computer worked for some time. After a day or two, scan to computer stopped working. After pulling out the printer's power cord and plunging it back print to computer starts working, but only for day or two. And I have to repeat it after day or to if I want to use print to computer. Everything else works. And this problem are on all computers on company network. Also, if it don't work I get this
After pressing on Fix button, opens Scan Doctor (I update it if it asks to update). Scan Doctor stops on "Driver check" step.
I pull out the printer's power cord and plug it again. Then press on button "Restart Computer". After computer restarts I run Scan Doctor again and get similar window.
After I press on button "Skip" all are green.
Scan to Computer works, but only for day or two and I have error on printers web application.
Exactly the same problem was with the other printer HP OfficeJet 7510, now it is broken so we change it to HP OfficeJet Pro 7740.
