The printer has burned a scanner assembly. The part number is RM1-2033-030CN. The part is extremely expensive in relation to the printer cost. ($182.00 @ HP)

I would recommend surfing ebay for an HP Laserjet 1022 printer as it is the cheapest printer that has the same scanner. Even a dead 1022 will work as they tend to either have formatter or fuser issues when dead. A scanner error on your printer or the 1022 is extremely rare.

I have included a link to the HP 3050 service manual for you that will walk you through it step by step. The teardown is significant however very do-able by the novice with the service manual.

Good luck, You can do it.

The device has experienced an internal hardware error. Recommended Action

1. Turn off the power by using the power switch, wait at least 30 seconds, and then turn on the power and wait for the device to initialize.
2. If the error is still unresolved, contact Hewlett-Packard for technical support to troubleshoot the problem. Call HP for telephone support

First, power the printer off, wait for about 30secs and power on. If problem persist replace the scanner.
