Question about Lexmark T642 Laser Printer
Hello my friend,this is printhead error,check connections at both ends of cable for corosion or oxidation,reconnect them.Also can be system board error.You can check the operation of
the printhead shutter and clean the printhead window with a lint-freecloth folded over a cotton swab; do not use a bare swab and do not use any cleaning fluids or water on the printhead window if you see the defect on the photo conductor.Good luck:)

Welcome to FixYa!
If this is the first time the error has occurred, try turning the printer off.
Restart your computer.
Let the printer sit turned off for at least 1 minute before powering it back on.
Make sure it is plugged straight to the wall and not through a surge device or power strip. Power strips and uninterrupted power supplies can cause a low amperage problem in your printer. This can trigger a printhead error (For Lexmark Printers) even if the printer has worked on this surge device for months.
If the printer continues to post a 930 Printhead Error, it thinks the wrong printhead unit is installed.
The printhead unit and possibly the laser cable or the engine/system board to this printer may need to be replaced.
The printer needs to be serviced for it requires personalized tools that prevents further damage to the printer which the only the manufacture has it.
Keep me posted if solution 1 or solution 2 resolved the problem.
Thank you for using FixYa.
