Re: Hp Color Laserjet 5550
HP guy has the instructions to follow. However, what kind of environment is that machine in? I've got some machines out on factory floors, and if that machine is in a similarly awful environment you might try cleaning the laser unit if time allows. If you aren't dealing with an actual laser diode or polygon mirror motor failure, that might buy you some time until the new laser unit arrives. Or it might break the laser unit completely, so proceed carefully.

Re: Hp Color Laserjet 5550
Poor contact exists in the
primary charging bias or
developing bias contacts
between the print cartridge
and the product.
Clean each contact of the color that
produces the missing color. If the
problem remains after cleaning,
check the contacts for damage.
Replace any deformed or damaged
parts.
The print cartridge (primary
charging roller, developing
roller, or photosensitive drum)
is defective.
Replace the print cartridge of the
color that matches the defect.
The imaging high-voltage
power-supply is defective (no
primary charging bias or
developing bias output).
Replace the imaging high-voltage
power-supply.
The laser/scanner unit is
defective.
Replace the laser/scanner assembly.Leave a comment:
