failure.
010051 Next to uppermost SIMM
indicates a failure.
010052 Both upper and lower SIMMs
indicate a failure.
010080 RS-232-C data overflow.

Corrective Actions
Check encoder strip, carriage assem-
bly, trailing cable, main PCA.
Replace uppermost SIMM.
Replace next to uppermost SIMM.
Replace both upper and lower SIMMs.
Data byte was not read before another
was entered into the UART. Replace
main PCA. If problem remains report
the firmware problem to the HP
Response Center or the nearest HP

All 300XX errors indicate a failure of
hardware or electronics of the X- or
Y -Axis. Refer to SERVO CONTROL
SYSTEM FAILURES in this chapter.
Refer to code 030000.
Check mechanical parts in pen cap-
