Common Errors
20 ERROR
This error occurs when the printer runs out of memory during a
font download, macro creation, raster graphic download, or page
composition. To alleviate this error, the quantity of data sent to the
printer must be reduced. This can be accomplished by eliminating
unnecessary fonts or macros, reducing the raster graphics white
space sent to the printer, or selecting a lower resolution for the raster
graphics. An alternative solution is to install additional memory.
Additional memory is available from your Hewlett-Packard Sales
Representative or authorized dealer.
21 ERROR
This error results when a page is too complex to print. The error can
be corrected by reducing the complexity of the page, or by enabling
Page Protection mode from the control panel. (Refer to the “Print
Overrun” section described earlier in this chapter for additional
information.)
22 ERROR
This error indicates an I/O protocol problem between the printer and
the host system. Make sure the printer and the host system protocol
(hardware handshake or Xon/Xoff handshake) correspond and that
your cable is correct for your host/printer configuration.
40 ERROR
An error occurred while transferring data from the computer to the
printer. This error occurs if the computer is turned ON and OFF
while the printer is on-line, or if the printer’s baud rate, parity, or data
character size are not the same as the computer’s. To clear the error
message press [[CONTINUE/RESET]] (refer to the printer User’s
Manual). Make sure the printer is set to the same baud rate as the
computer, and that your host I/O has been configured for your printer.
If the error continues, call your HP Service Representative.
For additional printer errors, refer to the printer User’s Manual.
