3.3.8 Horizontal Stripe (FF activation) Test Print (PGTYPE=10)
Use the horizontal stripe test print to check the dark area density of each color, balance
between colors, and white lines (development).
a.Dark Area Density of Each Color and Balance between Colors
The density must not be appreciably light.
If a mono color copy is light, suspect a fault in the developer or the transfer blade.
If the density is light for all colors, suspect a fault in the up/down movement of the transfer belt.
b. White Lines (development)
For instance, if white lines are noted in the cyan area of the copied image, suspect a fault
in the developing assembly for cyan.
c. Uneven Density between Left and Right
If uneven density occurs between left and right for all colors, suspect dirt on the butting
block, and a fault in the height of the primary charging wire.
d.Image Position (left/right)
If the position of the cassette holder or the setting of ‘REG-X, Y’ is wrong, the registra-
tion between the copy paper and the image (left/right) will have a discrepancy, eliminating
the non-image width, possibly causing stray toner and soiling the inside of the machine.
