In the user manual they list some compatible printers that have a 25 pin parallel connector. We use Lexmark Optra E312L with good results. Once you hook it up, you have to go into one of the setup menus to port it over. The user guide tells the procedure.

Why does my zeiss humphrey visual field machine keep shutting down?


Sounds like a heat, thermal issue. You may have a non- functioning cooling fan somewhere inside. There are several of them so don't be fooled if you hear one of them running. Same issue happens with CPUs on PC computers. Will suddenly shut off if too hot.

Zeiss humphrey system startup state 19


I believe "state 19" is a weak main illumination bulb. Not sure if it's the same on your 740, but that's what the problem was with our 750i. Even though the bulb appears to be working, they dim over time and won't pass the start up calibration checks. On ours, there is a round access panel on top of the unit to service this bulb. Just be careful removing the bulb and don't bump any of the clear optical wheels. Part # 2660021106082 (for 750i. not sure about 740) Call Zeiss to confirm. Realize this is an old post so info is for future readers.

I keep getting a Load MP Feeder Letter message. I can't clear what to do?


MP Feeder refers to Multi Purpose Feeder or Manual Paper Feeder or just plain bypass feeder. There should be a door that folds down to gain access to your MP Feeder tray. Try loading letter size paper on this tray.

Make sure you have selected the multi purpose feeder (front of the printer) in the driver, not the Manual Feeder.

The manual feeder will prompt for paper on each page. All you have to do is to press the "Go" button.
