Turn printer power switch to "off" and remove AC power cord from AC outlet. ******************************************************************** * WARNING * * * * HIGH VOLTAGE IS PRESENT IN THE POWER SUPPLY AREA. MAKE SURE * * THAT THE POWER CORD IS DISCONNECTED FROM THE AC OUTLET! * * * ******************************************************************** 2). Open the top cover, using a 4mm allen driver, loosen the three printer mechanism lock screws (button head, socket, black color), one on the left side and two on the right side of the printer mechanism, and fully raise the mechanism. (See Figure 1, Page 4) ************************************************************************* * CAUTION * * * * ENSURE THAT THE SAFETY LATCH ARM IS FULLY ENGAGED BEFORE RELEASING * * THE MECHANISM! * * * ************************************************************************* **NOTE** REFER TO THE DIAGRAM ON PAGE 5 FOR STEPS 3 TO 5: 3). Using an 8mm hex nut driver, loosen the air hose clamp at the band motor and disconnect the air hose. Cut the air hose tie straps, one located about 8 inches below the band motor and the other at the top of the power supply cover, pull the air hose into the power supply compartment and move it away from the circuit card assembly. 4). Locate and examine the power supply circuit card assembly (C.C.A.) cable connectors. Make a note of the position of the commectors before disconnecting them. The recorded information will be used to reconnect the power supply cables. Disconnect the power cable connectors on top of the power supply safety cover. Using a 7mm nut driver, remove the 3 hex head screws on top of the safety cover and remove the cover. Disconnect the remaining power cables on the left side of the C.C.A. Using a 8mm hex nut driver, remove the 2 stand offs at the front of the C.C.A. The stand off located at the rear of the C.C.A. does not have to be removed. The new power supply C.C.A. will have a stand off attached to it. Using a 9MM hex driver, remove the 2 hex nuts at the rear corners of the C.C.A. Using a 7mm hex nut driver, remove the 4 hex head screws that are used to fasten the 2 power supply capacitors to the C.C.A. Remove the power supply C.C.A. _ _ _ _ _ _ _ | FCO LP37-S001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 3 OF 6 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ 5). Install the new power supply C.C.A., re-fasten the 2 capacitors, the front 2 stand offs, the screw to the rear stand off, and the nuts at the rear of the rear of the C.C.A. Reconnect the power cables to the left side of the power supply C.C.A. with the information recorded in Step 4. Re-install the safety cover with the existing hardware. Re-connect the remaining power cables on top of the safety cover. 6). Re-connect the air hose to the band motor and fasten the clamp. Re-tie the air hose to the cables that were originally tied together with the new tie strap. Use the other tie strap to secure the air hose on top of the power supply safety cover. 7). Lower the printer mechanism and tighten the three printer mechanism lock screws. ***************************************************************** * CAUTION * * * * MAKE SURE THAT THE BAND MOTOR AND TRANSDUCER CABLES DO NOT * * INTERFERE WITH THE OPERATION OF THE SAFETY LATCH ARM, BAND * * DRIVE PULLEY OR THE CHARACTER BAND. * * * ***************************************************************** 8). Locate the FCO decal on the AC power switch cover and record FCO information. 9). Load the paper and close the top cover. FUNCTION CHECK: 1). Turn the printer AC power switch to "on". 2). Verify that the printer is operational using available diagnostics. _ _ _ _ _ _ _ | FCO LP37-S001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 4 OF 6 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ FIGURE 1 _ _ _ _ _ _ _ | FCO LP37-S001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 5 OF 6 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ FIGURE 2 _ _ _ _ _ _ _ | FCO LP37-S001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 6 OF 6 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ LARS CATEGORY S USA EUR GIA Activity - (a)Contract and Warranty W U (b)IN-DEC Contract K Hardware Segment Code 111 Non Contract/Non Warranty F F (c)RTD/Off-site Agreement F Product Line 031 DEC Option LP37-AA/ LP37-AA/ LP37-A3 LP37-A3 Type of Call M M Action Taken D D Fail Area-Module-FCO-Comments LP37-S001 LP37-S001 Material Used EQ-01603-01 EQ-01603-01 (a) Warranty Optimum, Warranty Standard and Warranty Basic (on-site) Agreements.
