ADDITIONAL INFORMATION:

To remove the paper jam the fuser area of the printer must be disassembled. Fusers and pressure rollers should be checked for damage from the paper jam or the customers attempts to remove the paper jam.

The output tray fin should be installed in all LaserJet 5L's in the affected serial number range that are returned for any service, paper jam or other. Solution:

The out try fin (RB1-7332-000CN) should be placed in the output tray of the printer. This will decrease the number of fuser paper jams customers are experiencing. The fin should be installed in all printers that do not already have it. See graphic for placement of the part.

LaserJet 5L Printer Fuser Jam Clearing Countermeasure To Be Performed By: HP-Authorized Personnel Parts required: RB1-7334-000CN JP (Jam Prevention) Protector General Description:

When a paper jam occurs in the LaserJet 5L it will commonly occur in the fuser area, with the paper folding accordion-style between the fuser and delivery assembly. The paper jams in the fuser can be such that the customers cannot remove the paper and the printer requires servicing. Customers attempting to clear the jams often cause damage to the printer. This countermeasure will not prevent paper jams, but will allow users to clear the paper jams without damaging the printer.

To remove this type of paper jam the fuser area of the printer must be disassembled. The fuser and pressure roller should be checked for damage from the paper jam or the customer's attempts to remove the paper jam. See chapter 6 in the service manual for disassembly instructions.

This JP protector and the output tray fin (from service note C3941A-01) should be installed in all LaserJet 5L's in the affected serial number range that are being serviced.

Solution:

This JP Protector (RB1-7334-000CN) should be added to the delivery assembly (RG5-2012-000CN) of every printer in the affected serial number range that is serviced. To install this part you must remove the delivery assembly, per the service manual (page 6-13/14). The JP Protector is shown in Figure A below. The Delivery Assembly is shown in Figure 8-10 of the Service manual. Install the JP Protector into the Delivery Assembly in the position shown in Figure B below. Figure B shows a right side view of the Delivery Assembly with the JP Protector installed. Be very careful to orient the part correctly.
