Section 4: Problem Solving

Problem: Nothing happens when I turn on the printer.

Solution: The printer may not be plugged in. Check the power cord connection to the outlet and to your printer. If you’re using a power strip, make sure it’s turned on. Check to be sure that the fuse hasn’t blown or that the circuit breaker hasn’t tripped.

Problem: The printer doesn’t print when the computer sends data.

Solutions: (1) The printer may be deselected. If the SEL light is out, press the SEL button to select the printer.

(2)The printer cable may not be securely connected. Check the cable to be sure that it is properly connected to both the PC and the printer.

(3)If you have installed the serial I/F board, it may not be firmly seated. Check to be sure that the board is firmly seated in the printer.

Problem: I’m getting strange symbols, incorrect fonts, etc., when I try to print a document.

Solution: The printer driver you have engaged does not agree with the emulation selected for your printer.

To check the emulation selected, first make sure paper is loaded, then press the SEL and SHIFT buttons simulta- neously to enter the MENU on your printer. Next, press the GROUP button: this will print the emulation selected.

If the emulation is not the one you want to use, press the SET button to change it to the one you want before exiting the MENU (to exit, press SEL and SHIFT but- tons).

If the emulation is correct, check your software docu- mentation on how to select a printer driver, then check to be sure that you have selected one of the drivers listed for that emulation in Section 1. The closer the driver is to the top of the list, the more compatible it will be with your printer. If your software doesn’t have any of the indicated drivers available, check with the software manufacturer to see if they have added any additional drivers since you purchased your software.

If you have embedded any printer commands in your software, check to be sure that you entered them correctly.
