Error Message 57 for HP P4014, P4015 & P4515 Printers.

  • Error Message 57 for HP P4014, P4015 & P4515 Printers.

  • The P4014 printers have four fans. The combination of low-melt polyester toner and a large catridge suggests the printer innards have to be kept cool, however the high speed suggests a powerful heater in the fuser so the printer has to be able to counter that effect with sufficient air-flow. Used continually a P4014 series printer is close to being a 1 kilowatt heater, so it needs those fans.

    57.XX ERROR
    57 Error is one of the fans. The printer has four fans in its base model and the duplexer adds a fifth as it partly blocks the fuser vent area. Although they are nicely engineered fans they are a bit noisy and there are suggestions that as the printers get older, the axles and bushings get a bit eccentric and foam cushioning ages the machines get prone to rattling noises.

    Laser printers almost invariably use heat to fuse the toner into the page. It takes a considerable amount of energy to raise 60 pages per minute to about 150 centigrade for fusing to take place. In operation the P4014 series use just under a kilowatt of electricity on average - so it is acting as a small fan heater. The fuser is not totally efficient at transferring all that energy into the paper so the fans are needed to extract it from the printer.

    The P4015 and P4515 machines have a rather large cartridge full of special low-melting point polyester toner that is intended to save about 15% of the electric cost of running the fuser. However this toner does need to be kept cool even though the developer end of the cartridge is innevitably next to the fuser.

    The fans feed clock signals back to the DC controller so it can detect them not moving properly. However there are suggestions that this doesn't always work as it should because the fuser can go to 50.3 and 50.9 overheat errors.

    It is worth making sure that users are not blocking fan vents with things like ledger files piled against the machine. Yes, the printer does make a handy bookend on a desk but it also needs about 150mm (6 inches) clearance on all sides for adequate ventilation.
