3. for much more than three minutes the printer prob ably has an initialization problem There are two main types of problems that cause hung displays on the 4345 On the one hand it could be the for matter or something plugged into the formatter On the other hand it could be caused by the engine power supply or the FN101 fan The following troubleshooting sequence will help you discover which part is causing the problem Ideally you would have all parts available that are listed at the end of the article If not the procedures described in this article will probably require two service calls 1 Troubleshooting to determine which parts are needed 2 Repair installing the parts If the printer is at a remote site much of the troubleshooting can be done over the phone with the customer Alternatively you may want to treat this as a depot repair where the printer is brought to your shop I Is it the Formatter Formatter Plug ins or the Power Supply Fan A Observe the heartbeat LED visible just below the parallel port or on the M4345 below the USB port see figure 1 In a working printer this LED will flash briefly on power up turn off during the memory count and then pulse on and off in a regular pattern while the HP logo is cycling If this LED is not pulsing while the logo is cycling the problem is formatter related If the LED is pulsing its hard to be sure so we need to run an engine test Go to step
4. is Bad When troubleshooting a hanging display on a LJ 4345 once you have ruled out the formatter that leaves either Fan 1 FN101 or the Engine Power Supply We at Liberty have found a way to test the power supply without swapping parts saving time and money This will require removing the front cover This involves manipulating hidden plastic tabs and removing screws display 2 When the memory count begins on the M4345 before the memory count begins press and hold the 9 key until all three LEDs flash once and then stay on this may take up to 20 seconds then release it 3 Press and release the 3 key and then the Start key 4 Press and release the 3 key as many times as needed until NVRAM INIT appears on the display 5 Press and release the 6 key to select this and wait for the printer to com plete the initialization sequence 6 If neither reset solves the problem replace the firmware DIMM then the base memory then the formatter if necessary NOTE Almost everything in this article applies equally to the LaserJet 4345 and the LaserJet M4345 However note that the NVRAM initialization procedure is slightly differ ent on the M4345 Also it does not have a separate firmware DIMM or base memory DIMM these are built into the formatter board Parts Mentioned in this article Ideally you would have all parts below If not the proce dures described in this article
5. the inner surface of the plate Laser Printer Halfway Test The halfway test also called the stop test is a useful way to isolate print image defects To perform the test print something and then stop the paper halfway through the printer by opening the lid This works best if you feed from the manual or MP tray because you can watch the paper feeding Open the lid just as the trailing edge of the page disappears into the printer Now remove the toner cartridge Ideally the page will be stopped between the toner cartridge and fuser with part of the image on the page but unfused and part of it still on the drum in the toner cartridge Observing these two partial images can help you decide where the defect is originating There are three possibilities I There is no defect visible in either partial image Assuming that the defect is not intermittent and happens on every printed page this eliminates everything before the fuser Therefore the defect must be originating in the fuser Il The defect is visible on the paper but not on the drum This eliminates logic boards laser scanner toner cartridge and fuser Either it is a transfer issue bad transfer roller or high voltage or a mechanical issue rubbing or vibration in the area between transfer and fuser IIL The defect is visible in both partial images This eliminates transfer and fuser The defect originates in the toner car tridge high voltage laser scanner or lo
