5050/5100 User's Manual
If the serial host does not stop sending data when the printer reports
busy, the input buffer will eventually fill to capacity. Any additional
data sent by the host will be discarded and an error condition will
exist. This error may be reported to the operator via GenPtrOpts
(Group 1) strap 16. See "GenPtrOpts" in Chapter 3 and General
Printer Options Group 1 table on page 184 in Appendix G for
additional information.
Parity, Framing, and UART overrun characters will be replaced in the
data stream with the "*" character.

When Strap 16 is enabled, the action performed is the same as Strap
16 disabled but a message is displayed and printed, and the printer
is placed in an off line condition. Press the CLEAR key to continue.
The 33 print heads in this printer are identical. If a replacement print
head is temporarily unavailable, rearrange the heads so that the
defective one is located in an area that is least likely to be used.
Relocating the defective head to the far right end of the shuttle would
still allow a full 12.8-inch line (128 characters at 10 cpi).
Print heads for the 500-lpm printers have one actuator. See Figure 7-
2. Print heads for the 1000-lpm printer have two actuators.
