HP LASERJET 2200 ERROR LIGHT FLASHING

[Marty]

Hi All,

Having a nightware with a laserjet 2200dn.
The error light is flashing all the time.
The computer tells me that the printer has no paper in it but there is?

I have performed cold resets on EIO, NVRAM,

I have exchanged formatter board, engine controller board, registration
assembley for paper sensor in tray 2, i have checked rechecked all
connections to every component to this printer.

The only option left is the main power board, this has a wire running
from it to the paper sensor for tray 2, is it possible that there is no
current reaching the sensor from the board even if all other part are
OK?

Any advice would be appreicated.

Kind Regards

Martin Cummins

Martin:

One fo three things could cause that problem:

1). Fuser Exit Sensor is knocked out of place or the Optical Sensor at the
Fuser Exit Sensor is bad.
2). Toner Cartridge is not being detected.
3). The Top Cover latch is not activating the switch.

When you turn the printer on, do you hear the Motor running? Noise or no
noise??? If you don't hear the motor running, most likely cause #1. Remove
the Fuser assembly and check the Sensor flag arm and the sensor itself.
Use compress air to clean teh Optical sensor.
