A client recently contacted us to have a 30K paper sensor overnighted to him.
Below was our response.
We currently do not have any in stock and would need to ask Secap to drop ship it, and lately they have little to nothing in stock and would most likely ship it from another facility, when available.
On another note, the only time I've ever needed to replace it, is when it was damaged by chemicals or the plastic housing was broken.
Normally we can clean the sensor with a small paint brush and air.
Please make sure the compressed air you use is "Safe to use on all Sensors and other electronic energized equipment like "
Clean Jet 100"
Be careful the sensor is on a delicate plastic housing and can easily break!
If that doesn't work then adjust the sensitivity of the sensor.
We recommend having a trained service technician do the following. If you are In PA, NJ or DE call All For Mailers Inc. at 866-430-2874 otherwise you can give Secap / PB a call at 800-523-0320
You can adjust it by going to the Service Menu by taking the printer Off Line them holding down [Menu] and the [-]
