[rescue] LaserJet 5P Fuser problem

Generally the parts are available to rebuild fusers.....

Either the sensor that senses the fuser's temperature is bad, or the
heating element is bad.... I'd imagine both can be replaced.

If you go the way of fixing the fuser... you may want to check any gears
on it, as well as the surface of the actual fuser roller... if there are
any chips or scratches, replace it.

Last time I fixed a laser printer (Canon SX engine in a QMS), I ordered
the parts from The Printer Works (www.printerworks.com).

Checking there now, I see that is a Canon VX engine in there.  I don't
seem to see the parts you would need to rebuild.

First thing I'd check is all the electrical connections... maybe one has
become bad (for the sensor or the heater).

Unless you have a bad electrical connection, if the problem is in the fuser,
I think your looking at $128.25 for the fixing film assembly (which may have
all you need), or $232.75 for a whole new fuser assembly.... yikes...
makes me miss Cannon SX based engines... cheap and plenty parts, built like
a tank.... just doesn't have the DPI and speed that people want/need these
