HP LaserJet 4 and 4M Notice
HP LaserJet 4 and 4M Notice — Mark H. Anbinder passes on this note from Hewlett Packard. "Be sure to follow step number 10 in the "Setting Up Your HP LaserJet 4 Guide." The guide refers to two levers which need to be pushed down before operating the printer. These levers engage the fusing assembly. The print will not fuse to the paper and will smear if the levers are not pushed down. The documentation shows a picture of the back of the printer and the levers but tells the user to follow the instructions on the packaging material, which is not very descriptive. It is likely that this step will be skipped by many users and technicians alike."
