not be selected.If the communication link between your 
computer and the printer is working but 
the printer ejects a blank page when 
printing from your application or through 
Windows, make sure that the 
appropriate driver is installed and that 
you have selected the printer correctly.
When parallel interface is used

■If the print out is ragged
If the print out is curled as illustrated, this can occur because of the natural curl of the paper, 
remove the media tray from the printer and turn the stack of paper over, then install the media 
tray.
■A tip when printing on transparency
When you notice some straight lines on the projected image on the screen (OHP), it is 
recommended to open the rear cover, so the media is printed straight out.
■If you cannot install the printer driver in Microsoft® Windows NT® 
operating system Version 4.0
The printer driver cannot be installed with Add Printer Wizard in Windows NT 4.0. Install the 
printer driver with Setup.exe [see “Installing the Printer Software (For Windows)” in the Setup 
Guide].
