Faulty printer
Printer not correctly connected.
No paper.
FAULT: Read/write site data (SSW), CU xx
SSW = data that is changed during operation, i.e. sensor values, access
codes, etc.
If the C.U. was made powerless (i.e. no mains and no the
battery) without first doing a Safe shut down of control unit
via menu H8/S8 (see page 149), this fault might be generated
when the C.U. is powered again. After fault acknowledge the
SSW will get default values and the fault will be corrected
(serviced).
Some external influence has caused a fault in the SSW. This is
very serious. Call for service personnel/engineer.
