Customers are | | experiencing high incidence of failure from the Power Amp PCB due to its | | minimal current carrying margin and lack of shut-down capability in its | | design. This FCO implements ECO: 3026069-00001 | |______________________________________________________________________________| | PROB/SYMPT: The most common symptoms experienced are as follows: | | 1. Printer stops and no error message is displayed. | | 2. Printer stops and Paper Motion error is displayed. | | 3. Prior to printer stopping, paper won't move or moves excessively. | |______________________________________________________________________________| | QCK CK: See page 2. | | | |______________________________________________________________________________| | COMPATIB/PREREQ: N/A | EST INSTALL TIME | | | 1.0 hours | |______________________________________________________________________________| | TOOLS/TEST EQUIP: o Phillips screwdriver | | o Small Flathead screwdriver | | o IC extraction/insertion tools (DEC PN: 29-24015-00) | | o ESD kit (DEC PN: 29-11762-00) | |______________________________________________________________________________| | FCO PARTS INFORMATION | |______________________________________________________________________________| | ORDER BY | CONTENTS | | FCO KIT # |_______________________________________________________________| | |QUANTITY PART NUMBER DESCRIPTION | | EQ-01529-01 | 1 See page 2. | | FA-04829-01 | 1 LG01 FCO Documentation | | FA-04830-01 | 1 LG02 FCO Documentation | |______________________________________________________________________________| | EQ KIT VARIATION/SYS-OPT APPLICABILITY: Only one kit for all variations. | |______________________________________________________________________________| | APPROVALS | |______________________________________________________________________________| | CSSE ENGINEER | F.S.

Check the printer serial numbers: LG01-A2 86073 LG01-A3 85443 For printers having lower serial numbers, check Revision Levels: 1. On the Unit, check for the DEC Part Number ( LG01-A2 or LG01-A3) label (may not be present) inside the right side panel for Rev A02. 2. On the Power Amp PCB and CPU EPROM (socket 4B, See Figure 1), check the Vendor Part numbers: a. Power Amp PCB for Rev G. b. CPU EPROM (socket 4B) for number 700524_111.2 For anything less, the printer must be upgraded by the FCO. FCO Parts Information: Continued from page 1.

Unplug the power cord from the printer. Disconnect the data cable using the small screwdriver. Remove the paper basket. 2. Remove the rear panel of the printer as follows: a. Remove the 10 plastic caps which cover the rear panel retaining screws. b. Loosen the 11 retaining screws. c. Lift off the rear panel. ******************************************************************* * C A U T I O N * * All of the modules in the card-cage contain electrostatic * * sensitive devices. Use the ESD Kit mentioned in the special * * tools section. Put the appropriate end of the ESD strap * * around your wrist, and attach the other end of the strap to * * the printer frame. Spread out the ESD Mat so that you can * * set the PCBs on it as they are removed from the machine. * ******************************************************************* 3. Remove the plate that holds the card-cage PCBs in their slots. 4. Remove the Power Amp PCB from the card-cage as follows: a. Locate the Power Amp PCB. See Figure 1 on page 5. b. Grasp the Power Amp PCB by the locking tabs (ejectors) at the top and bottom, lift the ejectors away from the PCB and pull the PCB free from the card-cage. c. Place the PCB on to the ESD Mat. 5. Install the new Power Amp PCB as follows: a. Remove the Power Amp PCB from the ESD bag in the kit. b. Grasp the PCB at the top and bottom, and carefully slide it into the slot, with the component side facing to the left, where the old PCB was located. c. Press the PCB into the backplane, and close the ejectors. _ _ _ _ _ _ _ | FCO LG01-R001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 4 OF 8 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ Installation Procedure: Continued 6. Remove the Control CPU PCB from the card-cage as follows: a. Locate the Control CPU PCB. See Figure 1 on page 5. b. Grasp the Control CPU PCB by the locking tabs (ejectors) at the top and bottom, lift the ejectors away from the PCB and pull the PCB free from the card cage. c. Place the PCB on to the ESD Mat. 7. With the Control CPU PCB "resting" on the ESD mat replace the EPROM in socket 4B of the PCB as follows: a. Locate the EPROM (700524-111.1) in socket 4B. See Figure 2 on page 6. b. Using the extraction tool (PROM puller), remove the EPROM (700524-111.1) from the socket. c. Insert the new EPROM (700524-111.2) into the socket using the insertion tool. Make sure to align the U-shaped notch on the EPROM with the U-shaped notch on the socket. Be careful not to bend any pins, and make sure the EPROM is seated firmly in the socket. 8. Replace old part number label on Control CPU PCB with new part number label. Use label: 610424-34 for LG01 and, 610424-35 for LG02. 9. Install the Control CPU PCB with the new EPROM as follows: a. Grasp the PCB at the top and bottom and carefully slide it into the slot, with the component side facing to the left, where it was previously. b. Press the PCB into the backplane, and close the ejectors. 10. Install the plate that holds the card-cage PCBs in their slots. 11. Disconnect your static strap from the printer. 12. Install the rear panel as follows: a. Position the rear panel on the frame and align the holes for the retaining screws. b. Tighten the retaining screws. c. Install the plastic caps by pressing them onto the rear panel retaining screws. 13. Open the panel door and attach the appropriate (LG01 A2 or LG01 A3) DEC part number label from the EQ kit to the right side panel inside the printer next to the existing serial number labels. _ _ _ _ _ _ _ | FCO LG01-R001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 5 OF 8 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ 14. Install the power cord, the paper basket and the data cable, and power-on the printer. 15. Verification testing: Refer to Appendix A. 16. Be sure to return the Power Amp PCB and the EPROM, which were replaced, to FS logistics.
