Solution
1. Replace the printer cable. If the problems not solved even
after the cable replaced, check the amount of the remaining
tone.
2. Check if the connection between PC and printer port is
proper. If you use windows, check if the printer driver in the
controller is set up. If the printer driver is properly set up,
check in which program the printing is not working. The best
way to find out is to open the memo pad to check the func-
tion of printing. If it is not working in a certain program, adjust
the setup the program requires. Sometimes, the printout is
normal within the Windows basic programs, but it's not work-
ing in a particular program. In such case, install the new
driver again. If not working in the Windows basic program,
Check the setup of the port of CMOS is on ECP. And check
the address of IRQ 7 and 378
3. If the scanner needs to be connected to the printer, first the
remove the scanner from the PC to see if the printer is prop-
erly working alone.
Solution
1. Not working with the message 'insufficient printer memory'
means hard disk space problem rather than the RAM prob-
lem. In this case, provide more space for the hard disk.
Secure more space using the disk utilities program.
2. The connection of the cable and printer port is not proper.
Check if the connection is properly done and if the parallel
port in CMOS is rightly set up.
3. As a printer port, Select ECP or SPP among SPP(Normal),
ECP, and EPP modes(increase printing speed) SPP normal
mode support 8-bit data transfer, while ECP Mode transfer
the 12-bit data.
4. If the regular font is not printing, the cable or the printer
driver may be defective.
Turn the PC and printer off, and reboot the system to print
again. If not solved, double-click the printer in my computer
If the regular fonts are not printed this time again. the cable
must be defective so replace the cable with new one.
