Touch Screen Calibration

For LJ 4345 MFP, 4730 MFP, 9040/50 MFP, 9500 MFP, M3027/M3035, M4345, M5025/5035, M9040/9050, and the 9200C digital sender

The LaserJet 9000mfp uses a different procedure.

The control panels of the larger HP multi-function printers (MFPs) are touch screens: instead of pressing buttons to navigate printer menus, you touch different areas on the glass display itself. Occasionally, these displays become unresponsive and require calibration to restore functionality. Despite the fact that service manuals routinely overlook this issue, there is a standard procedure for monochrome and color MFPs released by HP since 2004.

  1. Press and hold the number (#) and “C” keys while powering on the printer.
  2. Release these keys when a small dot or square appears in the upper left corner* of the display.
  3. Precisely touch the small dot or square with a pointed, but not sharp, object. The manuals suggest a stylus or a pencil eraser, but a pen cap will do – do not use anything that will scratch or mark the screen.
  4. A second small dot or square will appear in the lower right corner* of the display. Touch this dot in the same way.
  5. After a few seconds, the printer will resume its normal boot sequence. Once it reaches the “Ready” state, it should operate normally.

*The details vary on some models. If both dots appear at once, touch the upper left dot first, then the lower right dot. If they appear in different corners than described above, touch the dots in the order that they appear. If the second dot does not appear, redo the calibration procedure.
