Dirty background throughout the page:
This may occur when the user turns on the main switch without removing the tape seals or when the
cartridge has been shaken after the seals are removed.
The position of the toner agitator is adjusted at the factory. When the main switch is turned on, the main
motor turns the agitator. After the user removes the seals and resets the cartridge in the machine, the
agitator is no longer in it's proper position, which causes dirty background on the printouts.
If the cartridge is shaken after the tape seals are removed, dirty background may occur, as the developer is
not evenly distributed in the development unit.
SOLUTION:
This symptom may occur during installation. If it should occur, please advise the customer to print out 30 to
40 pages. In most cases, the symptom will gradually disappear.
In addition, as a preventative measure, please advise customers to be sure and follow these instructions.
•
Remove the seals before turning on the main switch.
•
Place the cartridge on a level surface when removing the seals.
•
Once the seals have been removed, do not shake the cartridge.
Note: This only applies to cartridge installation and replacement.
From March 2001 production, the following changes were implemented to alert customers to these points.
•
Strips of yellow tape have been added that will stick out of the machine, reminding the user to remove
the tape seals inside before turning on the main switch.
•
A label and caution sheet has been added cautioning the user not to tilt the cartridge when removing the
seals.
