Question about Printers & Copiers
I tried all the different ports and I can't understand why it won't print. It is hooked up to my laptop via a usb connection. I downloaded the drivers fro HP and even tried uninstalling a reinstalling. The only time it ever printed it just printed wing dings or gibberish
1 Do self test without connecting to computer, if page prints properly print engine is ok.
Note this does not test function of input port at back of printer.
2 Test usb port from computer by connecting to another known working device. (Another printer, or Scanner).
3 No response change USB cable for anorther, if cable tests ok connect to 940c printer. if still prints garbage, input PCB is shot. Buy new printer.
Ps. The fact that your printer is printing garbage means it is getting instructins from your computer, A fualty computer USB port. the connencting cable, and the USB input can corrupt a good signal from the compurter.
