| Printers Affected |

4Plus, 4Mplus |
| Description |
|
SER=Serial interface, PAR=Parallel interface MIO=I/O card. For serial or parallel configuration, the computer and printer are not communicating because of improper signal protocols.
Parallel Configuration:
May mean a loose, cable connection,or a bad or poor quality cable.
Set High Speed to No and Advanced Functions to"OFF" in the Parallel Menu on the front panel of the printer.
Serial Configuration:
1. Wrong pacing option may have been selected. The HP LaserJet printer uses XON/XOFF and DTR/DSR signal protocols rather than ETX/ACK protocol.
2. If an error 22 is encountered with the HP LaserJet 4 Plus Printer in a UNIX (R) environment Robust XON/XOFF may need to be turned off.
MIO Configuration:
1. This is an I/O buffer overrun error. If you are using an I/O card other than the serial/Bi-Tronics Parallel I/O supplied with the printer, see the manual for that device or contact your dealer. If on a network, contact the network administrator. |
