We have an HP Laserjet 2500 that has stopped printing. The Go, Ready and Attention lights are all on and solid. I followed the instruction in the manual by disconnecting the power from the power strip and plugging it directly into the wall. I also Turned the printer off and back on and left it off for 15 minutes before turning it back on. Since none of this worked I pressed the Go and Cancel buttons to get the secondary light pattern. This shows the attention and the ready lights on solid but I can not find that particular pattern in the documentation. HP wants me to pay them to advise on this issue but since this is a School printer, I am not authorized to pay for this support. also, I know the principal will want to weigh the repair cosrt against the cost of a new printer.Please advise as to what the problem might be.
