Printer Problems Lexmark C750

By technogeek-1995 ·
At my school, I have a Lexmark C750 printer. It runs in a cycle between "Preforming Self Test" and "Error 90." I have no clue what is wrong. We can't print to it and my IT teacher is getting very mad at it. The IT people can't come for some time now...Please Help!!!

Turn off the printer and reboot your computer(s)..

Hopefully this should fix the problem.
If not then i will post plan B.
Is this a USB device?

Please post back if you have any more problems or questions.
If this info is useful, please mark it helpful. Thanks

Memory Error

by LarryD4 In reply to Printer Problems Lexmark ...

Error 90 on the Lexmarks usually means an internal memory read error.

Even if a reboot and power on works get it tested completely.

I agree it's probably a Memory Error

But if you can tell us what has been done recently to this printer it would help no end.

Because it is in a School Environment it may have exceeded it's Page Count and need to be reset follow the directions here

When replacing the fuser on the Lexmark C750, C752, C760 or C762, follow the instructions below to reset the fuser count.
