Canon LBP-2000 User Manual page 175

Printing garbled text.
Cause1 : If unexpected letters and symbols are printed on the page, the operating mode
setting may be incorrect.
Remedy : Make sure that the PERSONALITY item in the ETHERNET MENU, PARALLEL
MENU or USB MENU is set to AUTO or the correct personality (PCL or PS) is
selected, if the printer is dedicated to one personality.
Reference : "PARALLEL MENU" (See p.7-28)
"USB MENU" (See p.7-30)
"ETHERNET MENU" (See p.7-32)
Cause2 : The printer selection you made when you set up or installed your software
application was incorrect.
Remedy : Make sure the correct printer is selected.
Reference : See the manual provided with your software.
Cause3 : If different portions of the text are garbled every time you print, the interface
cable may be too long, and spurious noise is corrupting the data.
Remedy : The maximum length for the parallel cable is 3 meters. If your cable is longer
than this, replace it with a shorter cable.
Cause4 : The printer is plugged into an outlet shared with another electrical device
capable of generating noise, such as a photocopier, shredder or air conditioner.
Remedy : Plug the printer into a different outlet or consult a qualified technician to install a
noise filter.
Printing overlap.
Cause : If another print job starts before the current job is finished, the flow of data from
the host computer has been interrupted for some reason, and a job timeout has
occurred. If data is not received for a specified length of time, the printer initiates
a job timeout and terminates the job. After the job timeout, the printer
automatically switches to the other interface when there is data waiting.
Remedy : You may have to increase the I/O TIMEOUT setting or disable it in the
PARALLEL MENU or USB MENU.
