Q: What is a "B1" sensor error?
A: B1 refers to sensor number B1, or in simpler terms one of the temperature
sensors for the “B” heater (also known as the fixer heater). This can error can
occur for a couple of reasons. 1) The heater control board has detected a
temperature reading it did not expect, this could be caused by a rapid increase or
decrease in a heaters output. Cycling the power on the printer will usually reset
this condition. 2) If this error continues after cycling power or occurs on a regular
basis it is usually the result of a faulty temperature sensor and/or control board.
If this occurs during the warranty period please contact your local dealer to setup
a maintenance call.
Other related errors: Each heater set whether it be the ‘A’, ‘B’, ‘C’ or ‘D’ have
temperature sensors associated with them. If this error occurs for one of the
other heaters i.e. “’C’ sensor error” the same rules would apply. Please note that
the ‘B’ and ‘D’ heaters are broken into two banks B1/B2 and D1/D2.
