5.4 IMAGE PROBLEMS

If you have a problem with the printed image, first check and correct the
following items:
'
1. Is the printer cable correctly connected?
2. Is the proper printer cable used?
3. Does the image problem occur only in printer mode? (Is the image in
copy mode OK?)
4. Does the emulation mode of the printer match the selected driver?
5. Is the same font used between the printer and the software?
6. Is toner saving mode on? (If so, turn it off and recheck.)
If the problem still occurs after correcting the above items, proceed as follows:
1. Does the problem occur only when printing a downloaded font?
→If yes, reinstall the font.
2. Is "Memory Overflow" or "Print Overrun" displayed during printing? (The
printed image will be partially blank in this case.)
→If yes, more memory needs to be installed.
3. Does the problem occur when you print the PCL font list?
→If yes, replace the controller.
4. Does the problem occur when you print the PostScript font list?
→If yes, replace the printer enhancement unit.
