Troubleshooting. Test Print
Grid (TYPE=1)
Check item |
Check method |
Assumed cause |
Right angle accuracy/ Straight line accuracy |
Check whether lines in the horizontal/vertical scanning directions are paralleled to the paper and these lines are at right angles to one another. |
Feed system failure or Laser Scanner Unitfailure is considered. |
Side registration |
Check the left margin. |
Floor at the installation site is extremely distorted, or the feed system failure is considered. |
Magnification ratio |
Check whether the grid is printed at 9.99mm intervals. (Check the image on the second side at duplex printing.) |
Rollers' feed system failure or laser exposure system failure (drum, Laser Scanner) is considered. |
17 gradations (TYPE=2/3)
Check item |
Check method |
Assumed cause |
Gradation |
Check whether gradation in density is made appropriately. |
Drum failure, laser exposure system failureor developing system failure is considered. |
Black line |
Check whether black lines appear on the image. |
Laser light path failure, developing system failure, cleaning (drum) failure or transfer roller failure is considered. |
White line |
Check whether white lines appear on the image. |
Developing system failure is considered. |
Solid white (TYPE=4)
Check item |
Check method |
Assumed cause |
Fogging |
Check whether foggy image appears in the blank area. |
Drum failure, laser exposure system failureor developing system failure is considered. |
Halftone (TYPE=5/6/11/12/13/14)
NOTE:
When outputting a halftone test print, be sure to use PG TYPE:6 except in the following cases.
- When checking the image of side registration adjustment, use PG TYPE:11.
