Question about HP LaserJet 2840 All-In-One Printer
Cleaned the glass and light bulb. but still the problem persists.
Scanner errors are as follows for that model:
Scanner error #
1 = dark find
2 = LMW temp find
3 = bulb warm up from off
4 = bulb warm up from coarse
5 = cal label find
6 = doc original find
7 = LMW final find
8 = cal label find after scan
9 = cal label find prior to standby
10 = doc original find prior to standby
11 = bulb warm up from standby
I would see if there is an original on the flatbed glass (platen), or if something is obstructing the scanner view.
If the error persists, replace the scanner
assembly or the formatter pcb
