P-4
Headers or footers are not printed out even though they are viewed on PC
screen.
User Check
Most laser printers have a restricted area that cannot be printed on. Usually the first two lines and last
two lines of text cannot print (leaving 62 printable lines). Adjust the top and bottom margins in your
document to allow for this.
P-5
The printer prints the first couple of pages correctly, then some pages have text
missing.
User Check
A problem related to serial interface setting. The PC is not recognizing the printer’s input buffer full
signal. Causes could be incorrect serial cable (incorrectly wired or too long) or incorrect setting of the
computer serial interface.
P-6
The printer sometimes prints a couple of characters and then ejects the page.
User Check
This problem sometimes occurs when the PC power is turned off while the printer power is on. Turn
off the printer power first before turning off the PC.
