Are you talking about Color registration problem ?
Usually caused by dirty registration sensors
To calibrate the sensors, perform the following:
1. Disable Color Registration Correction Control in the 25 mode, software dip switch 25, bits 3 to 1 (ON) and bit 4 to 0 (OFF).
2. Run the [Auto Color Registration Adjustment] in the 36 mode.
3. Try Running the Manual Registration Adjustment.
4. Remember to enable Color Registration Correction Control after the adjustment.
If the problem persists, there could be a dirty or failed color registration sensor (PS8 or PS9). Check their operation in the 47 service mode. Replace the failed sensor, if necessary.
As the HP9850 is a Konica C500 try the Konica Forum to have better answer Have only 1 of those machine in the field
