The HP Laserjet P3005 printer models offer high speed printing, up to 35ppm on letter sized paper. The P3005 models also use Hewlett Packard’s FastRes 1200 technology, enabling the printer to produce 1200 DPI quality output. This feature can be turned off as well, increasing print speeds and reducing toner usage.
The P3005 models look a lot like the 2400 model printers. They share the same grayish looking covers. The P3005 models have a 500 sheet standard input tray. The 2400 models use a 250 sheet tray as the standard tray, with an option for a 500 sheet tray. They also share a common problem. Over time as the printer is used and parts start to wear some new noises might be heard coming from the printer. It might start off as low groaning sound, almost like its struggling to turn the gears in the printer. The printer is still working ok. There are not print quality defects or paper jamming problems. The noise sounds like it is coming from the rear area of the printer so a fuser replacement might be in order. The fuser is a high wear / failure part in most laser printers so it’s a logical place to start. The fuser is not too difficult to replace on this printer.
After replacing the fuser and the printer is turned on, you now hear new sounds coming from your printer. The noise has not gotten better it has gotten worse. Now it might sound like some gears might be broken, loud chattering noises coming from the right side of the printer. So now you are thinking you have gotten a defective replacement fuser or possibly installed it incorrectly. To test your theory you re-install the original fuser back into the printer and you find that it sounds much better. You are back to your original noise (s) in the printer. Now you are convinced that you have a defective replacement fuser as you have seen and heard for yourself that the original fuser works without all the extra sounds coming form the printer. This is not the case though.
What has happened to the fuser / printer is that the bushing on the pressure roller in the fuser has worn down. If you look at the right side pressure roller you will see the plastic dust of what remains of the bushing. As this is occurring more and more downward pressure is being put on the gears in the printer that drive the fuser. When a replacement fuser is installed it has new bushings and is now back to when the printer was new. The problem is now the rest of the gears on the printer do not mesh properly with the fuser anymore. There is a noise upgrade gear kit available. This along with stronger bushings on the fuser pressure roller should help to keep your printer running smoothly. When replacing the fuser on the P3005 / M3027 / M3035 models there is good chance you will need to install the gear kit as well. It comes with printed instructions and the gears are not that difficult to replace once you have the fuser removed. There are some instances where even replacing the fuser and the gear kit does not quite the printer completely. There is another set of gears in the paper output assembly which are available in a kit and might be needed as well.
The formatter on the P3005 has been a sore spot for this printer as well. No display, freezing up, not booting up, locking up while printing a job. The list of problems is quite extensive. The formatter is flashable, so it can be upgraded with the latest firmware. If you can get the printer to a ready state its worth trying to upgrade the operating system on the board. It’s free and you have nothing to lose. With the N model (embedded network) extra memory is required for the network to operate. There will be a DIMM in the slot and this must be working for your embedded network to work. If the network features are not working before replacing the formatter, check that the memory is OK by testing it in another printer if one is available. There is another fix out there for flaky formatters and it requires an oven. Evidently the solder joints on these boards crack and shrink causing intermittent component failures. The fix is 8 minutes in a 350 degree oven. Evidently this will reflow the solder on these formatters. I guess it’s worth a try if the board is unusable in its current state. Again you have nothing to lose as long as you don’t overcook it !!
