Networks and switchboxes
The printer’s status read-back feature requires a direct connection
between the printer and the computer. Most devices connected
between the printer and the host computer prevent the printer from
sending data back to the computer.
If you use a mechanical switchbox, follow these guidelines:
● Do not switch while the printer is printing or receiving data (when
the Ready light is blinking).
● Do not switch to a host computer that is OFF and then turn that
computer ON. The Ready light on the printer will blink as if the
computer is sending data. If the Error light is blinking, reset the
printer. To do so, press and hold the control panel button for five
seconds, and then send the job again.
● Use a surge protector.
Out of memory
If the Error light is blinking, the page may be too complex for the
printer’s memory capacity. To clear this error, briefly press and
release the control panel button. Printing will resume; however, some
data loss may occur. To avoid this error in the future:
● Reset the printer. To do so, press and hold the control panel
button for five seconds.
● Set resolution to 300 dpi with your software.
● See Help for more suggestions regarding printer memory usage.
