Spreadsheets are at the heart of many business systems, either as core tools or to serve as a supplementary data analysis tool. My objective is to provide resources and tools that will enhance your Excel experience.
I will also share solutions to some of the office hardware problems that I’ve had to solve. For example, one of the printers in the office is a Brother 8440. Attempting to clean the drum raised an error that would have been a service call if we couldn’t find a quick solution. The error reads “Machine Error 78 – Shut down and Call Brother.” Not very helpful.
We Googled the error message and found a site that offered a variety of solutions http://www.fixyourowncomputer.com/forums/laser/26155
If removing the toner cartridge and re-inserting does not solve the problem, try the following solution to eliminate the error:
- Unplug the printer and wait several minutes.
- Plug the printer back in and HOLD down the menu key while the printer starts up.
- Press * 9 then 1 for parameter initialization
- Press * 9 then 9 to perform a full reset
The solution worked and the problem has gone away.
