My church has an OKI 5400n that had a 020 fatal error on the display.
I reseated what appears to be labeled a ROM chip on the mainboard, and it worked for another two weeks.
Repeating the process today did not recover, so I believe we have two options. Either replace that chip, which I have been unable to locate (it looks like a small simm), or buy a new printer.
I believe the OKI was about $1400 new, but they got it second-hand.
They do not need to stick with OKI necessarily, but I believe they will want the replacement to be just as fast.
It is identified as a workgroup printer. It would need to have it's own network interface and compete with the following specifications.
Up to 24 ppm - B/W
Up to 16 ppm - color
1200 dpi x 600 dpi -B/W or color
I found a couple that would be faster B/W printing, but drastically lower in color. I have had difficulty finding the same dpi settings or better as well, so I am looking for recommendations here. I will increase points for any information on the ROM chip, or the fatal error condition as well.
Thank you for your time.
