Service checks

CAUTION
Service checks which involve measuring voltages on the LVPS/HVPS (low voltage power
supply/high voltage power supply board) should be performed with the printer positioned on
its back side.
Note: When making voltage readings, always use frame ground unless another ground is
specified. See the wiring diagram in the back of the book for more information.

900.xx system software error service check

There are different types of 900.xx errors that can occur. There may be a communication problem (Bad cable,
network connection, and so on) software issue, or a hardware problem with the RIP board, or ISP (Internal
solutions port). The communication and software aspects should be checked first. Determine if the problem is
constant or intermittent. Use the troubleshooting procedure below to isolate the issue. Take any notes as
instructed. You will need that information in the event you need to contact your next level of support.
Note: Before troubleshooting, determine the operating system used when the error occurred. If possible
determine whether a PostScript or PCL file was sent to the device when the error occurred. Ask the customer
which Lexmark Solutions applications are installed on the device.
