HP LaserJet IIP error code 51

"I have here a HP Laserjet IIP which gives errocode 51. The manual says something about a beam-detection. Do you guys 'n girls think this is to repair for relatively little money?

(From: Osceola Electronics (osceola@netonecom.net).)

On my IIP+, I had to take it all apart. I had to remove the main board and open the main cover to the laser area and clean the fiber-optic pickup and lens.
